Ordinary metal garage can perform many the most useful functions. During the winter, a caring car enthusiast leaves his car there, someone else stores provisions here, and someone equips the space for a special workshop. All this can be done provided that the garage must be insulated.

Optimal temperature for such a room – at least -5°C. At lower values, condensation will begin to form on the surface of the car, which leads to rust. It will be impossible to work in a box because of the cold, and storing vegetables will become impractical; they will simply begin to rot at the first thaw. In order to retain heat inside the room, it is necessary to select and install the insulation correctly.

Insulation materials

Using traditional metal garage building materials can significantly increase the temperature in the room.

For these purposes use:

• Foam plastic. This material is considered the most common type of insulation. It is convenient to work with polystyrene foam; it is cheap;
• Penoizol. This is a liquid form of the same foam. Penoizol has fire resistance and excellent water resistance. The durability of such insulation is 40 years;

• Basalt wool. This soft and inexpensive insulation is also called mineral wool. Garages are often insulated with mineral wool. And this material is one of the leaders in terms of popularity of use.
• Polyurethane foam. The durability of this building material is 50 years;

The above types practically do not differ in quality; reasonable prices determine the demand for all these products.

Having decided on the type of insulation for arranging thermal insulation from the inside of the box, you can begin the preparatory stage.

Necessary tools and building materials

It is better to insulate a garage in summer or spring. Sometimes the situation forces work to be carried out in cold weather, at low temperatures. In this case, it is necessary to insulate the garage reliably quickly.

You need to prepare the tools in advance to use the allotted time productively:

• electric drill;
• building level;
• steel profile;
• welding machine;
• screwdriver;

• self-tapping screws;
• furniture stapler with staples;
• roulette;
• wooden blocks for installing sheathing crossbars;
• scissors for working with metal;
• protective gloves, special mask.

Preparation

When dealing with the internal cladding of metal structures, first of all you should take care of anti-corrosion. If there is rust on the surface of the walls, it should be removed with a special metal brush. If necessary, patch repairs of individual areas are carried out. After which the surface is treated with an anti-corrosion solution.

To ensure optimal conditions indoors, you also need to create ventilation system. It will be needed for circulation: the system will remove exhaust air, replacing it with fresh air. Otherwise, accumulated heavy vapors and gases can cause condensation. Condensation has a negative impact on the condition load-bearing structure garage, car and stored products.

After applying the anti-corrosion solution, it usually takes several days for it to dry completely. Then they begin to insulate the box from the inside. This kind of work can be done with your own hands. According to the rules, first the walls are insulated, then the roof, gates, and only then, if necessary, the protection of the floor is strengthened.

Wall insulation

Let's consider the insulation procedure using the example of a material such as basalt wool.

This type of material has decent characteristics:

• durability;
• preservation of qualities even at high humidity;
• low thermal conductivity;
• resistance to mold;
• ease of working with insulation;
• environmental friendliness;
• fire resistance.

The sequence of covering garage walls with mineral insulation:

• First you need to determine the location of the sheathing. The amount of material used will depend on the square footage of the sheathed surface. Steel profile Great for frame construction. The use of wood in this case can lead to rapid destruction under the influence of moisture. In addition, the wooden structure can become deformed when wet.
• Start building vertical guides. The gap between the structures should be about 1-2 cm, that is, less than the width of the insulation itself. This way the material will expand completely and take up the entire space. To strengthen the system, horizontal transverse beams are placed every meter; wooden beams can be used here.

• The already installed sheathing begins to be surrounded by a membrane; another type of waterproofing material can be used. The joints that appear should be glued with tape, the film is attached to the staples, you can use a stapler for this.
• The insulation needs to be laid inside the resulting sheathing. Start laying from the bottom. In this case, no crevices should remain.
• A vapor barrier material is applied to the insulation, you can use plastic film or roofing felt.
• Finally, the sheathing is sheathed. The sheathing is made of non-combustible material, for example, plasterboard or steel siding is used.

It should be taken into account that when covering a box, the space in the room narrows. Accordingly, it is better to choose not very voluminous insulation.

When covering a garage with foam plastic, you should take into account the peculiarities of the material. Such insulation will not expand like cotton wool, so it is better to make the gap between the guides a little smaller, for example 1-2 cm. It is better to create the sheathing in separate blocks, the dimensions of each of them should exactly repeat the dimensions of the foam sheets. If there are defects on the walls, then it is better to level the surface before insulation. It is recommended to use the profile L-shaped. Insulation sheets are attached with glue

Roof insulation

Typically, the roof or ceiling of a garage is presented in the form of a lean-to structure. This roof design is considered budget and simple option. The basis for it is rafters resting on the Mauerlat.

At the stage of its construction

Now let's continue working. The mauerlat bars are laid on top of the box walls, secured with anchor bolts. It is better to carry out thermal insulation of the ceiling of an iron garage at the stage of its construction. In this case, you will need to go to work less strength and time.

The rafter system is assembled from wooden beams. The cross-section of each beam is 15x15 cm. The rafters are installed at an evenly equal distance, the gap reaches 60 cm. The main guideline in this case is the width of the insulation boards, according to the standard this size reaches 61 cm. The maximum thermal insulation elements can be laid between the rafters if there is a reserve .

The next stage will be the installation of a vapor barrier layer. To do this, you can purchase special membranes that are perfect for these purposes. They are attached to the rafters with staples and buttons. Existing joints are taped. From the inside of the building, the vapor barrier is sheathed with the selected material. Here you can use fiberboard or lining. This is an individual solution for each garage owner.

The sheathing is attached very carefully; it is necessary to ensure the tightness of the vapor barrier. Damage or defects that appear during operation should be repaired immediately. To do this, you can use sealant or tape.

The insulation is installed between the rafters. It is better to choose mineral wool for such work. Usually, the use of insulation with a thickness of 15 cm is considered sufficient. The thermal insulation layer can be increased if necessary.

Then they carry out standard technology for arranging the roof. First, the sheathing is made. The installation procedure depends on the characteristics of the roofing used. Afterwards, waterproofing is laid on the sheathing and the work is completed by laying the finishing material.

Thermal insulation after construction of a garage

The work on arranging thermal insulation of the ceiling, carried out after the construction of the garage, is slightly different from the process of insulating the roof during the construction of the box. In this case, thermal insulation is laid between the rafters, a vapor barrier film is laid on top, and finally the structure is sheathed with any suitable material.

Certain inconveniences may arise during the process of attaching thermal insulation boards. To eliminate the inconvenience, it is enough to simply fasten the insulation to avoid the material falling before the finishing sheathing begins. It is necessary to attach strips of waterproofing and vapor barrier material to the slings so that they prevent the insulation from falling.

It is considered inconvenient to work with the use of hard materials, therefore, sheathing the garage ceiling better than polystyrene foam. In this case, there should be no holes on the roof surface outside or inside. If there are still holes in the ceiling, they must be repaired by welding. At the time of insulation, foam plastic is placed between a vapor barrier and a waterproofing material.

Entrance trim

When cold air enters through the cracks located in the entrance gates of the garage, the benefits of insulation interior walls No. Laying rigid insulation, such as expanded polystyrene, will help solve this problem. First, the gates are insulated, and then the front door.

Sequence of actions:

• The metal surface of the gate is treated with protective mastic. A material such as polystyrene foam is not afraid of the negative effects of moisture. But when opening the doors, snow or raindrops can sometimes penetrate into the crevice, ending up between the insulation and metal sheet. This cannot be allowed.

Technical condition The performance of a vehicle depends not only on its operating characteristics, but also on its storage conditions. An uninsulated garage perfectly protects the car from rain and snow, which reduces the likelihood of rust. However, temperature changes do not benefit the metal, and the equipment fails. The problem can be solved in two ways: insulate the garage or install a heating system. Which is better? How to insulate a garage from the inside cheaply and reliably? Let's consider the options.

To heat or to insulate – that is the question

The ideal temperature for storing a car is +5 degrees. It is uncomfortable for humans, but it is in such conditions that mechanisms are less susceptible to the destructive effects of corrosion. The car should also be protected from sudden changes: the temperature difference between inside and outside the room should be minimal. Therefore, connecting the garage to the heating system and achieving “human” +20 degrees is undesirable.

Insulated garage for two cars

Why is this mode optimal for the car? If the room is too hot or cold, condensation begins to accumulate in the mechanisms. This promotes corrosion. Due to increased humidity, fungi and mold multiply intensively, which negatively affects the condition of the interior. Sudden temperature changes also lead to the formation of condensation when a car drives from a frost into an excessively warm room.

Basic requirements for garage insulation

For the construction of garages, brick, cinder block or metal are most often chosen. The thickness of brick and cinder block walls is usually 120-250 mm. They do not protect well from the cold, so they need high-quality thermal insulation. It is necessary to achieve the so-called “thermos effect” so that the room cools and warms up as slowly as possible.

When insulating a garage from the inside, you don’t need to try to seal everything ventilation holes. This will have little effect on the quality of thermal insulation, but can lead to other problems. If you don't have access fresh air, moisture does not evaporate and rust appears on the metal. In addition, harmful gases accumulate in the room. If there is no exhaust or ventilation, this can become a risk factor for people.

How to insulate - from the inside or outside

Many car owners advocate exclusively for external insulation, explaining this by saving space indoors. There are also more weighty arguments, for example, concern for people's health.

Pay attention! Some effective insulation materials emit harmful substances into the atmosphere. It is not advisable to use them indoors, but for external thermal insulation they fit perfectly.

When choosing what to cover the outside of your garage with, you can pay less attention to the environmental friendliness of materials and buy based on performance characteristics and price.

It makes sense to insulate the garage from the inside. In this case, the materials are less exposed to negative factors environment. When wet, thermal insulators change their properties. If they are located indoors, they last much longer.

Advice. If your budget allows, it is best to insulate the garage inside and out.

Materials market review: choosing the best

Most thermal insulation materials are made from industrial waste. They contain glass, cellulose, aggressive chemicals, etc. The cheaper the insulator, the more disadvantages it has. We offer an overview of popular materials with an emphasis not only on their advantages, but also on their disadvantages and limitations in use.

Installation of mineral wool on the ceiling

Option #1: mineral wool

This is a traditional heat insulator that has been used for decades. There are several varieties of mineral wool, among which basalt has proven itself to be the best. It is an excellent heat and sound insulator and does not interfere with micro-circulation of air in the room.

Mineral wool is produced in the form of hard, soft or semi-rigid mats of various thicknesses. Solid slabs are most convenient to install and have higher technical and operational characteristics. In addition, hard mats do not slide off the walls or get knocked down, as sometimes happens with soft ones.

The installation technology is relatively simple. The work does not require special equipment, so many owners choose mineral wool to insulate the garage from the inside with their own hands.

Pay attention! Mineral wool does not tolerate moisture well. When wet, it retains heat much worse. When calculating the costs of materials, you should add the cost of high-quality vapor and waterproofing insulators.

Scheme of an insulating cake with mineral wool

Option #2: glass wool

Glass wool is one of the cheapest heat insulators. This is where its advantages over other materials end. When installing glass wool, it is necessary to use protective equipment. When particles of the material get on the skin or in the eyes, they injure, cause microtrauma, itching, and redness.

The insulation needs high-quality waterproofing. If moisture gets on it during installation or operation, the glass wool crumples and loses its heat-insulating properties. Another minus is the smell. In a room insulated from the inside with glass wool, the smell remains unpleasant for a long time.

Advice. Glass wool must be carefully insulated with films or foil.

Glass wool for insulating garage walls

Option #3: foam

When deciding how to inexpensively insulate a garage from the inside, many choose polystyrene foam. This is a cheap, reliable and durable material that can last for several decades. It does not rot, is not afraid of insects and fungus. It can be cut with ordinary tools. No assistants are needed for installation. Lightweight material, convenient to use.

Like all other thermal insulators, polystyrene foam is not perfect. It does not allow air to pass through, so high-quality ventilation must be organized in the insulated room, and the joints between sheets of material must be well sealed to prevent condensation from accumulating.

Foam plastic is resistant to many chemical compounds, but at the same time it is afraid of direct sunlight. Mice happily chew on it. If you don't take care of additional measures protection, rodents can destroy insulation within a couple of years after installation.

Option #4: polyurethane foam

Polyurethane foam is relatively new material, but has already become popular. It is valued for its resistance to external influences. The insulator is not afraid of moisture. After drying it forms a dense hydrophobic coating.

After application, polyurethane foam expands, fills all cracks and voids, firmly adheres to materials, so condensation does not accumulate under it. The material does not support combustion and can last more than half a century.

Despite all its advantages, insulation is not without its drawbacks, the main one being difficulties with installation. Application of polyurethane foam requires special equipment. It is advisable that the work be carried out by professionals. All this leads to an increase in the cost of thermal insulation, but the finished coating justifies the investment.

Application of polyurethane foam on metal walls

Option #5: Reflective Insulation

The advantage of foil backed insulation is that thermal energy reflected back into the room. Polyurethane foam is usually used as insulation. The total thickness of multi-layer reflective thermal insulation can reach 50 mm.

Foil materials prevent heat loss that occurs due to infrared radiation, but cope less well with those that occur through convection and heat induction. This is a minus. And the advantages include the small thickness of the insulating layer, the durability of the materials and resistance to all types of influences.

Option #6: warm plaster

How else can you insulate a garage from the inside? If the walls are made of blocks or bricks, insulating plaster is suitable. It contains special additives that retain heat well: polystyrene foam, sawdust or vermiculite.

The material has good thermal insulation characteristics, but for it to be truly effective, you have to apply a thick layer of solution. This creates additional stress on building structures.

Advice. Warm plaster It is better to use in combination with other types of insulating materials.

Option #7: Heat-insulating paint

When thinking about ways to insulate an iron garage, pay attention to heat-insulating paint. This material is a liquid solution of polymers with synthetic additives.

The finished coating has good thermal insulation properties. If we compare it with mineral wool, the indicators differ by 50 times (1 mm of warm paint retains heat in the same way as 50 mm of mineral wool).

After hardening, the layer of solution turns into a dense, vapor-permeable coating that does not interfere with micro-circulation of air and at the same time protects structures from exposure to water. The material is suitable for wooden and metal surfaces. Additional plus - simple technology application.

How to insulate a garage from the outside - step-by-step instructions

For external thermal insulation, you should choose waterproof materials, best in the form of hard mats. The cheapest option is polystyrene foam. It must be closed from the outside, so you will also have to purchase finishing materials. The thickness of the insulation must be at least 5 cm. You will also need tools for cutting slabs, a notched trowel for applying glue, and fasteners.

Work order:

• Surface preparation. The walls are thoroughly cleaned of old coatings, leveled, and dust free. Cracks, crevices, gaps are sealed. It is better to treat surfaces with a primer. This is not necessary, but it is highly recommended that adhesive composition grabbed well.

• Gluing sheets. The sheets are smeared with glue using a notched trowel and pressed tightly to the surface, controlling the pressure so as not to damage the fragile material. The first row is placed on a pre-prepared plank secured to dowels. The rest are in checkerboard order.

• Additional fasteners. When the adhesive has dried, each sheet of foam should be additionally secured with plastic dowels.

• Plastering. After installing the insulation, its surface is covered with a layer of 3-5 mm of glue and a glass fiber mesh is laid, glue is applied again and plastered.

• The finishing touch is painting. When the plaster is completely dry, it is painted facade paint. The number of layers depends on the characteristics of the coating, so you should carefully read the manufacturer's recommendations.

External wall insulation with foam plastic

How to perform internal thermal insulation yourself

To properly insulate a garage, you need to finish not only the walls, but also the floor, ceiling, and gates. The choice of materials is extensive; every car owner can find exactly those that are suitable for his premises. Most often they choose foam plastic, mineral wool, and buy expanded clay for the floor. It makes sense to combine heat insulators, because... building structures are made from various materials.

Let's consider the main stages of work on thermal insulation of a garage.

Do-it-yourself thermal insulation from the inside

Stage 1: floor insulation

Usually the floor in the garage is poured with concrete, so it is better to insulate it during the construction stage. If the premises were purchased ready-made, then insulation will have to be abandoned, because... the floor level will rise significantly, which may create inconvenience. An alternative is to remove excess soil and deepen the floor.

Expanded clay for concrete floor

Work order:

• The earthen floor covering is leveled and thoroughly compacted.

• A 10-30 cm layer of sand is poured on top of the ground and compacted.

• Pour a screed over the sand cushion and wait until the solution dries.

• Expanded clay or sand are used as insulation. The materials are mixed with cement and diluted with water. Fill the floor with the prepared solution and dry it.

• When the insulating layer has dried, the finishing concrete screed is poured.

• Once the work is completed, the floor cannot be used for the next month. This time is needed for the materials to completely harden.

Stage 2: ceiling insulation

How to insulate the ceiling in a garage from the inside and why is it necessary? Warm air rises up - everyone knows this from a school physics course, so the ceiling must be insulated. Foam plastic is suitable as insulation. Taking into account the peculiarities of installing materials on the ceiling, it is difficult to find an alternative to this lightweight and convenient insulator. Sometimes mineral wool is used.

Scheme of ceiling insulation with mineral wool

Features of installing foam plastic on the ceiling:

• The choice of technology depends on the material from which the ceiling is made. If the ceiling is wooden, then the foam can be attached directly to the surface with ordinary dowels or nails.

• If the ceiling is a concrete slab, you will have to mount a frame and lay a heat insulator on it. In this case, sheets of material are secured with tape and then pressed against the outer skin.

• The cracks and gaps are filled with foam.

• The surface of an insulated ceiling can be treated with antiseptics, plastered, or painted.

Stage 3: insulate the walls

Before you insulate a metal garage from the inside, you need to straighten the walls if they are bent. Polystyrene foam, polyurethane foam and heat-insulating paints are best suited as thermal insulators. For rooms built from blocks and bricks, mineral and glass wool are often used.

Preparing surfaces for installation of insulation

How to install cotton insulators:

• The walls are cleaned of old coatings and a frame is made.

• Cotton insulation is placed on the frame, secured with special hooks.

• The insulation is protected with breathable vapor barrier films.

• The exterior finish can be anything. It is installed after laying the vapor barrier.

Adjusting mineral wool sheets to size

Insulation of a metal garage with polystyrene foam:

• Surfaces are prepared and degreased.

• The foam is mounted with glue, pressing tightly against the walls.

• The sheets are laid end to end, the gaps are blown in polyurethane foam.

• When the foam hardens, cut off the excess. The surfaces are puttied and painted.

Pay attention! When using polystyrene foam, remember that in the event of a fire it releases toxic substances into the atmosphere. It is necessary to strictly follow safety regulations, and it is also advisable to keep a fire extinguisher in the garage.

Applying foam to insulation sheet

Stage 4: defend the gate

How to insulate a garage door from the inside? The sashes can be finished with foam plastic in the same way as metal walls. If this is not enough, you can make a curtain. Thick fabric or thick plastic film is suitable for its manufacture.

Thermal insulation of walls and gates

General scheme for insulating garage doors from the inside:

• To begin with, a sheathing is made, into the cells of which sheets of insulation are then inserted and secured with glue and dowels.

• Joints, seams, and gaps are carefully sealed to prevent the formation of cold bridges.

• The foam is puttied, painted or covered with sheets of outer skin.

• When the thermal insulation work is completed, a curtain made of polyethylene strips 20-30 cm wide is hung in front of the gate. The length should be such that there is a distance of 1-2 cm between the floor and the curtain.

Insulating the ceiling in a garage with mineral wool:

Each car enthusiast decides for himself how and with what to insulate the garage. The main thing is that he himself is confident in the reliability of the chosen methods. If in doubt, you can always consult with other car owners and find out how they solved the problem. Even better, seek advice from professional builders. They will help you combine materials correctly so that the thermal insulation is effective, durable and relatively inexpensive.

A garage is more than just a place for a car. You can carry out repairs in it, sit in company and store unnecessary things. Only for all these purposes heat is needed.

But what to do on cold days, especially with a metal frame? You can, of course, install a potbelly stove or electric heater. But this is unlikely to help in the presence of drafts. A proper insulation metal garage contributes to a comfortable microclimate. That's why we'll talk about this.

Why should you insulate your garage?

First of all, remember that when heat and cold come into contact, condensation forms. This means that if the garage is not insulated, but heated, the car body may be susceptible to rust.

Cold has a bad effect on engine performance. In case of deep minus, the car will have to warm up for a long time. After all, the oil low temperatures becomes viscous.

The optimal indicator is considered to be from +5 to +25°C. Insulation will provide protection from both cold and significant increases in temperature.

When using various heating devices protected walls will keep the heat inside. Iron has a high heat transfer rate. It turns out that by heating the metal, we also heat the street. This leads to excessive energy consumption.

Preparatory work

High-quality insulation requires several stages in preparing the garage box:

Insulation of garage walls

You can protect walls from cold penetration:

• from the inside;
• outside;
• on both sides.

The last option is the most effective, but also the most expensive. More often used internal insulation. But it is convenient only at the beginning of construction. It requires free space around the walls. Also inconvenient is the reduction in the operating area. Thin insulation and heat-preserving paints will help cope with the latter.

Insulation with foil insulation

Basically, with one or both reflective surfaces, they produce roll materials. They are created based on:

• foamed polyethylene;
• mineral wool;
• polystyrene.

The thickness of such insulation is small. Foil retains up to 90% of the heat inside the garage. This makes it possible to reduce the thickness of the base. As a result, the insulation procedure has virtually no effect on the area of ​​the room.
Another advantage is the vapor and water resistance of the material. Foil prevents vapors from the room from reaching the metal. This protects the walls from corrosion. Thanks to this characteristic, money is saved on vapor barriers.

This type of insulation is attached to metal using wooden slats. The sheathing elements must be placed vertically. When positioned horizontally, the wood will be saturated with moisture flowing down the foil.

Before the foil layer is required air gap. It promotes air movement and natural moisture removal.

Insulation by painting

The advantage of this type of work is:

• simplicity. You can apply paint using a regular brush or roller;
• durability. The coating is resistant to mechanical stress, oil, gasoline and other compounds often found in the garage;
• moisture resistance. When drying, the paint forms a strong, elastic film that repels liquid;
• environmental friendliness All paints are made from safe materials;
• fire resistance. Charring of the layer occurs at a temperature of +260°C;
• efficiency. 1 mm of layer is equal to 50 mm of mineral wool.

The disadvantages of this technology include high cost material.

Insulation with mineral wool

This type of insulation has good characteristics. He:

• promotes fire extinguishing in case of fire;
• non-toxic;
• easy to process;
• has low weight.

You can purchase the material in rolls or slabs. Fastening occurs according to wooden frame. Another advantage of cotton wool is its compressibility. You can take a less rigid approach to measuring the distances between slats.

Before installing insulation, a moisture-proofing film should be secured over the metal. After installation, a vapor barrier is laid on the insulation. It is attached to wooden slats with a stapler.

Mineral wool fibers have high water absorption. When exposed to moisture, the material loses its insulating properties.

Foam insulation

The advantages of polystyrene foam:

• accessibility;
• variety of densities and sizes;
• low weight;
• low absorption of liquids;
• easy processing.

The foam is attached to the frame or with glue. The second method is less expensive, but more risky. You need to choose the right, highly adhesive adhesive composition.

In conditions middle zone Russia needs to use a 100 mm layer. But it is better to carry out a thermal engineering calculation before starting work. He will show required thickness material for conservation optimal conditions indoors.

Insulation using backfill

This technology is very simple and effective. It is only suitable for garages with a large area. After all, to install the frame you will need at least 30 cm of free space.

Insulation involves installing additional fencing inside the room along the perimeter of the walls. The space between the two structures is filled with insulating material:

• sawdust;
• expanded clay;
• foam granules;
• slag, etc.

It turns out something like well masonry.

The disadvantage of this type of wall insulation is the possibility of contents spilling out. In addition, mice can get in between the walls, but for a garage this is not a big problem.

The advantages are:

• ease of installation;
• efficiency;
• environmental friendliness.

External insulation depends on:

• absence of trees around the perimeter of the garage;
• sunny and warm weather;
• proximity to other garages.

It is made using the same materials as the internal one. The difference lies in the final finish. It should be stronger and waterproofing layer more dense.

Ventilation device

Excess toxic gases released by:

• running car;
• fuel;
• paint and varnish materials;
• oils, etc.

require mandatory ventilation. It is necessary that at least 190 m3/hour of fresh air enter the garage. But this detail of the room increases heat loss by 30%. Because ventilation pipes must be insulated.

Insulation of ventilation can be due to both materials and technology. For example, the “pipe in pipe” system allows you to warm the air coming from the street to room temperature.

The material for pipe insulation is:

• polyurethane foam;
• expanded polystyrene;
• isolon;
• felt;
• mineral wool.

Attaching materials to the box occurs:

• due to the locking system in the material itself;
• using plastic clamps;
• fixing with glue;
• wrapping it with tape.

Heat loss can be reduced by installing supply and exhaust system with air heating. It is also capable of purifying air masses, saturating them with ions.

Insulation of garage ceiling

The ceiling can be flat or sloped. The cost of insulating an uneven ceiling will be more expensive. Therefore, it is better to align everything to one level.

The materials for insulation are:

• dense insulation;
• bulk materials;
• soft mats.

When choosing any insulation, the installation technology is the same:

• We screw wooden slats onto the rough ceiling. The thickness depends on the chosen insulation;
• lay a layer of film, securing it to the slats with a stapler;
• hemmes the space between the slats with plywood or OSB boards. Thus, cells are formed on the ceiling. We sew up the space in parts;
• fill the cells with insulation, placing it on top of the lining

It is advisable to lay wires in protected boxes. This will eliminate the possibility of the insulation catching fire due to sparking.

Foam boards can be attached directly to the flow using glue or polyurethane foam. This will simplify installation, reducing insulation time.

Floor insulation

The floor is one of the most problematic areas of the garage. It is subjected to considerable loads and mechanical stress. Therefore, the insulation must be dense and able to withstand the entire vehicle.

Special slab materials are used to insulate garages. For example, they use polystyrene foam labeled PSB S-35. It is designed for high static and dynamic loads.

Insulation with less durable products is possible during construction load-bearing frame. It is created from metal profile. Metal beams are welded to the iron base. For these purposes it is better to use I-beams. The height of the element depends on the “pie” of the floor.

The following layers are made as standard:

• waterproofing sheet;
• concrete base 100 mm thick;
• insulation;
• waterproofing;
• leveling reinforced screed.

Reinforcement is carried out in two directions with Ø 8 mm reinforcement.

Floor insulation with expanded clay is done as follows:

• a waterproofing film is placed on the metal;
• Expanded clay backfill is laid on it;
• A film is laid on the expanded clay. This eliminates the possibility of cement seeping into the backfill;
• lies on top of the film metal mesh, serving as reinforcement;
• the base is filled with cement.

The covering can be left concrete or tiles can be placed on top of the screed. Reinforced concrete is also used for garage floors. It will protect the base and the insulation hidden underneath it.

• find hinges and bolts;
• cling to the floor, preventing closing;
• get into the opening, preventing a tight connection.

Before insulation, it is necessary to inspect the frame of the gate and gate for distortion. If cracks are found during closing, they must be removed by welding the necessary metal.

Knowing how to insulate a metal garage, you can create a cozy, dry and, most importantly, warm place to store vehicles. The right choice materials and compliance with the sequence of actions will extend the service life for many years.

How to insulate an iron garage from the inside - this question worries owners of homemade products and models industrial production. The structures are cheaper than permanent boxes, but every winter the shells need to be constantly heated. Otherwise, starting the car will be problematic. A simple task will help correct the situation - applying a layer of thermal insulation to all steel surfaces.

Let's look at the main options for self-insulating a steel box.

Materials and methods for insulating a garage

How to insulate a metal garage with your own hands and what materials are best to use - here are several ways to solve the problem:

1. If the space between the boxes and the means allows, best option- this is insulation with outside with wall lining with foam concrete blocks or simple brick. This is a more expensive option; you will have to purchase expensive blocks, pour an additional foundation, spend time on laying and make new design roofs. But the advantages of such a solution completely cover the costs, if, of course, boxing is legal. The room will be comfortable in summer and winter, especially if you add a layer of thermal insulation between the walls. It turns out to be a thermos effect. This will no longer be a shabby metal garage, but a permanent building.
2. It is recommended to insulate a metal garage from the inside using inexpensive mineral wool slabs. Basalt fiber does not burn and has high levels of thermal insulation. But you will need to make a fine lattice of wooden blocks on all parts of the room to fix the slabs between it, then you will have to spend money on the purchase chipboards or other durable material for covering surfaces. In terms of heat savings, this material is inferior to analogues. The main disadvantage of min. cotton wool - flowability of the material and adverse effects on humans. Therefore, if you plan to use the box for work, application this insulation is strictly prohibited.
3. Modern polystyrene foam material will allow you to quickly and easily create a layer of quickly hardening foam on the walls and ceiling, which is not inferior in terms of thermal insulation to any material. There is no need to use cladding, the foam hardens, and an even layer is easy to paint. But for work you will need to purchase or rent expensive tools and equipment. The price of the foam will also require certain costs. Therefore, using such material in a garage is not cost-effective. Expanded polystyrene is used mainly for insulation of private households or garden houses. In these places, a layer of foam is applied from the outside and then covered with finishing boards or materials.
4. Probably the most democratic and popular method of covering walls and ceilings using foam sheets. For fastening, it is not necessary to create rows of sheathing; the insulation is easily glued to the metal using simple polyurethane foam or construction adhesive. In terms of characteristics, the material is preferable to mineral wool, and in terms of price it is preferable to all other finishing options.

Let's look in detail at how to insulate a metal garage from the inside with your own hands using an affordable option.

Step-by-step instructions for thermal insulation of a steel garage with foam plastic

The process is divided into several stages.

Preparing for work

Before starting the main work, several preparatory operations are performed:

• We clean all surfaces with a metal brush or wire disk mounted on an angle grinder or in a drill chuck. In any case, we recommend that you remove the machine from the box, remove or cover racks or shelves with thick material, and use personal protective equipment. Be sure to wear safety glasses and a respirator, and clothes must be buttoned up;
• We cover the rotten metal with patches and scald it. If this is not possible, you can apply bandages made of several layers of fabric and sealant to these places;
• To ensure that the walls of the insulated box are not exposed to corrosion, we degrease the treated walls, ceiling, gate leaves with solvent and paint over the outer and internal surfaces primer;
• We prepare the foam sheets for work. If the walls and roof are made with “cards” (separate parts with edges curved inwards), the edges of the sheet will need to be made oval at the junction with the edge of the “card”. The thickness of the slabs is at least 40-50 mm, 25 mm sheets can be installed, but the level of heat loss increases significantly.

Important! Before you insulate your metal garage, think about ways to save money. It will help you save significantly on the purchase of consumables by purchasing them in a large construction hypermarket or on special offer. Such a purchase will save up to 25% of funds.

Let's move on to the main stage of work and answer the main question of the article - how to insulate a metal garage with your own hands?

Insulation of surfaces with polystyrene foam boards

We insulate an iron garage according to the following scheme:

1. We figured out how to insulate, we begin to sheathe the walls with sheets of material. Construction adhesive different names will successfully glue and secure the panels, we do not recommend buying expensive compounds, advertising does not always allow you to choose a reliable composition, and it makes no sense to pay for a brand.
2. If you plan to cover foam plastic slabs with finishing materials, to fasten them we make a sheathing of wooden slats, the size of which depends on the thickness of the insulation. We fix the bars either into card shelves or with self-tapping screws through the walls of the box. Often there is no point in attaching them; foam plastic is a fairly dense material. We install the sheathing along the edges of the finishing sheets and 1.2 lintels in the middle - this will be inexpensive and practical.
3. We cover the metal surface with a layer of waterproofing; you can use a simple plastic film, it will protect the foam layer from condensation.
4. Turning the sheet over inside Apply a layer up and along the edges liquid nails or polyurethane foam. We start gluing the panels from the bottom. We glue the plate, depending on the composition, you may have to hold the sheet a little so that the foam fixes it.
5. In a similar way, we secure the entire bottom row and move on to the 2nd row. We bring the panels to the roof.
6. Gluing foam plastic to the roof surface is a little difficult, but the foam will quickly fix it, although you will have to spend a little time atlas.
7. Foam sheets are trimmed with a simple knife or a metal file, they need to be adjusted tightly to each other so that there are no large gaps left;
8. Having finished with the roof, we insulate the gate leaves and the gate in a similar way.
9. We fill all seams with polyurethane foam so as to prevent the occurrence of “cold bridges” and the formation of a layer of condensation. You can use various construction sealants - the main thing is to completely fill the cracks and seams. If the foam protrudes beyond the thermal insulation layer, after hardening it can be easily cut off with a knife.
10. As decorative finishing they use fiberboard sheets, MDF, plywood, but these materials must be treated with a special impregnation before installation. If you plan to install shelving or wall shelves, their fastening is taken care of in advance. At the installation sites, we install and weld steel plates or a corner flush with a wooden block.

Do-it-yourself insulation of a metal garage from the inside is finished. Long execution time full cycle will not require any work due to the large size of the slabs and ease of fastening to the wall. More time will be needed for the preparatory stage. Not only the durability of the thermal insulation layer, but the entire structure as a whole depends on the quality and reliability of the preparation of metal surfaces, painting, and fastening of the sheathing.

If you plan to use mineral wool rolls as insulation, prepare a large number of bars. The sheathing is installed at a frequency depending on the width of the insulation boards. Everyone else preparatory work performed according to a similar scheme. We do not recommend using fiberboard sheets for cladding. As a last resort, you can install MDF panels, but it is better to use CBPB slabs, chipboard or thick plywood.

In conclusion, we note.

Any man can insulate a metal garage. The work does not require experience in performing complex welding or construction work. The main thing is to have knowledge step by step instructions carrying out preparatory and basic work, takes responsibility for work and one’s health. In this case, when minimum costs your steel box will always have a comfortable temperature in both winter and summer.

To keep your car safe, you must have a garage, preferably a warm one. For example, a metal garage in autumn - winter period damp, freezing. Owners of metal garages are faced with the issue of insulation.

How to insulate a metal garage for favorable car storage, especially in cold, rainy weather? Ideal conditions are considered when the temperature in the garage does not fall below +3 degrees. At this temperature, it is possible to start the engine without warming up.

Tools required in the process of insulating a metal garage with your own hands

• Thermal insulation.
• Wooden bars for sheathing.
• Fastening elements.
• Foam for covering cracks and joints.
• Construction tape.
• Waterproofing material.
• Screwdrivers, screwdriver.
• Vapor barrier material.
• Hammer.
• Metal corners.

You will need finishing material and fasteners for a specific material.

Insulation for metal garages

Insulation of a metal garage occurs after choosing the material. How to insulate an iron garage from the inside? This is a responsible process. How to insulate? What material should I choose to serve most effectively and be optimally suited for insulating a garage from the inside with my own hands? Additionally, you will need finishing material, as well as fasteners for this or that material.

The most popular thermal insulation is polystyrene foam, but there are many different options:

• liquid insulation;
• foam insulation;
• insulation boards of varying strength (foam plastic, penoplex);
• fibrous soft boards.

Slab insulation method

There are three ways to insulate a garage using slab insulation.

Insulating a metal garage from the inside using polystyrene foam

• This is the most popular method due to its inexpensive price and excellent thermal insulation properties.
• The material is moisture resistant and durable (up to 30 years of service).
• The disadvantage of the product is flammability, but there are types of PSB-S slabs that are resistant to fire and have the property of self-extinguishing.

Extruded polystyrene foam (penoplex)

This material is a type of foam. The option is superior to conventional foam in all characteristics:

• in terms of strength properties, penoplex can be used to insulate a garage floor and install the screed directly on the insulation;
• thermal insulation properties are 3 times higher;
• a three-millimeter sheet of penoplex (expanded polystyrene) replaces a 5-centimeter layer of polystyrene foam;
• penoplex is an ideal waterproofing agent, its use can even be done in water;
• the only drawback is the cost, it is almost 2 times higher than the cost of polystyrene foam. For many, the price of insulating an iron garage is a significant point.

Slab fiber insulation

Slab - fibrous material not the best for insulating a metal garage, no matter how dense the slab or mineral fiber mat is, it is susceptible to harmful effects humidity. At the slightest level of moisture in the insulation, its properties drop significantly and it does not adequately perform its function.

It is not recommended to insulate a metal garage with mineral wool; this is important to know. Condensation will form on insulation materials even with waterproofing.

Foam insulation

Foam insulation has the structure of polyurethane foam:

• Manufacturers of the material assure that the service life of the insulation is up to 50 years or longer. Very durable insulating material. The foam is durable and slightly inferior in thermal insulation properties to penoplex;
• This method has its disadvantages - the high cost of the material. To install thermal insulation, you need a specialist with expensive equipment for distributing foam;
• In principle, it is the same foam plastic, only in a cylinder. It has the advantage of seamless installation.

Polyurethane foam is not used as the main insulation due to its high cost; it is used to treat joints of tile insulation (foam plastic, polystyrene foam)

Liquid thermal insulation

Common liquid insulation materials are heat-insulating paints Asstratek and Corundum. It's expensive, but quick way insulation of a metal garage from the inside.

A 1mm layer replaces a 50mm mineral wool slab. Apply paint with a brush or roller. The coating is moisture resistant and durable. Service life up to 15 years. To provide a 1mm thick coating, 1 liter of paint per 1 m2 is required. Experts recommend application in two layers.

Options for insulating structures (garages, shells)

How to insulate a metal garage with your own hands? WITH liquid insulation Everything is very simple, take a brush, apply a coating to the surface with a roller.

Do-it-yourself insulation of a metal garage has several options, from the inside or outside of the structure. Insulation from the outside is not a suitable method in this case. Let's consider methods of internal thermal insulation:

• Before carrying out work, the foundation should be prepared. This stage is important and cannot be ignored in order to avoid rust and insulation detachment. Corrosion is the main enemy metal products. First of all, the metal is protected from rust;
• The unpainted base is treated with a metal cord brush. Or they put a special attachment on the grinder (drill). Thus, the work process will speed up. A sheet with old peeling paint is processed in the same way;
• If the surface has high-quality coating, it should not be removed. Under the insulation, the paint will remain unharmed for many, many years;
• If the garage is made of galvanized corrugated sheets, with a frame of professional pipes and angles, then this material already has reliable protection, which cannot be violated;
• After cleaning the base, degrease the surface (acetone, etc.);
• If you cover the metal with foam (penoizol), then the preparatory measures taken are sufficient. If polystyrene foam serves as insulation, it is necessary to paint the iron. You can coat it with Kuzbasslak, it is economical and reliable.

Installation of foam boards

If the garage walls are smooth, even, polystyrene foam will be an ideal insulation material. By purchasing penoplex, the cost will double, but you will save a maximum of 4 centimeters of space. It's up to you to decide what is most appropriate for you.

The strength of the insulation on the ceiling and walls of the structure is not significant. Moreover, if the material is covered with finishing. Indoor cladding is made using forcing, siding, fiberboard (rarely moisture-resistant plasterboard).

Finishing with foam plastic is an economical option; in areas with harsh winters, when the temperature is below 20-25 degrees, it is worth using foam plastic 10 centimeters thick; thinner material will not give the desired effect.

If polystyrene foam is used, a thickness of 7 centimeters is sufficient:

• Sheets of material are cut to the required dimensions to completely and tightly cover the walls and ceiling.
• Then the sheets are glued to the surface with any construction adhesive (liquid nails, etc.). If there is a loose fit of the sheets to each other, the seams are sealed with polyurethane foam.
• There is an option to use foam instead of glue (the foam is distributed over the sheet in strips, pressed against a wall or other surface). The foam will expand at first and the sheet will come off, so you should periodically press the sheet for 60 minutes.

There is another method, which requires double-sided foil-coated isolon (foamed soft polyethylene, coated with foil on both sides). Take thinner polystyrene foam, glue the isolon on top and get the effect of a thermos. In addition, silver isolon has a pleasant appearance.

But there is one inconvenience in the garage: you can’t do without shelves, all kinds of mounts for tools, and soft insulation will not hold these structures. What to do?

Polystyrene foam and isolon are ideal for insulating the roof of a metal garage. To insulate the walls of a metal garage from the inside with your own hands, you need wooden sheathing along the walls and gates of the structure.

Wooden bars are attached to a reinforcing frame, which is found in every metal structure. The frame can be made of a profiled pipe or a corner, it does not matter.

Holes are drilled every 25-30 cm. A wooden beam is screwed with self-tapping screws. For comfortable installation of the cladding, it is necessary that the height of the insulation be lower than the block.

Arrangement of gate lathing

• After fixing the sheathing, it is cut slab material By the right size(as accurately as possible to avoid large gaps).
• It is glued to the base and the seams are sealed with polyurethane foam.
• Next is made finishing, forcing or other material. OSB panels and plywood are also used for sheathing.

Izolon or a regular layer of foil glued on top of a sheet of foam multiplies the heat-reflecting effect several times. Many people heat the UFO garage with a radiator. The rays from the foil base are well reflected, even under the skin.

Do-it-yourself insulation of the garage floor from the inside

According to SNiP, if the foundation of a room is not insulated, then the loss of thermal energy is 20 percent. Likewise, in a garage, the floor plays a vital role in the microclimate of the room. The insulation blocks moisture coming from the concrete base.

• the soil is removed, approximately 15 centimeters;
• then the surface of the base is leveled and compacted;
• First, a sand layer is poured, which should be compacted;
• then foam boards, 5 centimeters thick, are laid. At flat surface the joints will be smooth and tight. Moreover, there are grooves in the slabs.
• the material does not need waterproofing, since it itself is an excellent waterproofing agent;
• 3-4 centimeters of sand is poured onto Penoplex;
• then the frame is connected in two layers of 10 mm reinforcement;
• filled with screed to a depth of 5-8 cm.

To fully insulate the floor, you need to install a blind area; many people skip this step. If the area around the structure allows, it is recommended to carry out this work to avoid freezing of the soil under the metal garage.

The width of the device corresponds to the level of soil freezing in a given area. As a rule, the blind area is made from 50 cm to 1 meter.

If it is not possible to insulate the floor using the method described above, then it is possible to use the method of an overlay floor. Mounted from wooden logs, insulation and screed. In this process it is important to process wooden joists moisture-proofing composition so that the wood does not absorb moisture from the concrete. Can be used roll waterproofing(technical polyethylene, roofing felt).

Instead of a screed, you can lay flooring(tongue and groove board, 1.6 cm plywood in two layers):

• high-density foam or polystyrene foam 50 mm thick is laid between the lags;
• the gaps become foamy;
• The floor covering is attached to the joists on top;
• The logs should be spaced 30-40 cm apart from each other. To minimize abrasion of the floor, you can lay linoleum on top.

Insulating a metal garage from the inside with your own hands is a simple process. You should carry out simple steps step by step and the result will please you. High-quality work is the key to a well-insulated O room for a car. A warm garage is very necessary, especially in the autumn-winter period.
