How to insulate an iron garage from the inside. We insulate a metal garage. Insulating a garage should start from the floor

A metal garage performs many useful functions. Caring car owners park their car inside it for the winter, other people simply store their summer harvest, and still others equip the box for a workshop. All these goals will be successfully realized if the garage is well insulated from the inside.

The minimum temperature for such a room is considered to be −5 degrees; Otherwise, the vegetables will rot, it will be cold to work there, and condensation will form on the car, causing rust. Therefore, it is advisable to insulate an iron garage from the inside in order to effectively retain heat.

Suitable materials for insulation

Significantly increase the internal temperature metal garage traditional materials and new items, the quality of which has been tested only by a few, can be used. Examples good insulation materials are:

  • polystyrene foam (the most common material, characterized by low cost and ease of use);
  • penoizol (liquid form of the above, with a durability of over 40 years, good water resistance, fire resistance);
  • astratek (another liquid insulation; material applied in a layer 1 mm thick is comparable in quality to a five-centimeter layer of mineral wool);
  • polyurethane foam (durable material with a minimum service life of 50 years);
  • mineral or basalt wool (soft, inexpensive insulation, second in demand after polystyrene foam).

The listed materials are almost the same in quality, and the demand for one or another is usually determined by price. Therefore, polystyrene foam and mineral wool are considered the most popular.

Having decided on the choice of material for insulating the garage from the inside, you can begin preparatory work.

Required Tools

It is advisable to insulate the garage in the warm season, but sometimes the situation forces you to carry out work when sub-zero temperature. Here there is a need to insulate the box quickly and reliably. To use time efficiently, the following equipment is prepared in advance:

  • electric drill;
  • mask and gloves (protective);
  • welding machine;
  • building level;
  • screwdriver;
  • self-tapping screws;
  • metal scissors;
  • tape measure from 5 m;
  • staples and furniture stapler;
  • wooden blocks for the horizontal crossbars of the sheathing;
  • steel profile.

If all of the above is present, it’s time to start insulating the garage from the inside.

Preparatory stage

When lining metal structures, it is paramount to take care of anti-corrosion treatment. To do this, use a metal brush to clean off rust if it is present on the surfaces, and, if necessary, carry out patch repairs (specific small area), then paint the surface with a special anti-corrosion solution.

Sometimes the right question arises - how to insulate a metal garage for a long time if the surface is treated? The second important factor in ensuring comfortable conditions inside the garage is the creation of ventilation. It should remove air from the garage, replacing it with fresh air. Otherwise, the accumulation of gases will cause condensation, which will negatively affect the load-bearing structure garage, car or stored food.

After waiting for 1-2 days for the applied anti-corrosion solution to completely dry, the insulation of the metal box from the inside begins. It is advisable to carry out the work in the following sequence - insulate the walls, then the ceiling, the gate with a wicket, and, if necessary, the floor.

Insulation of garage walls and ceilings

The process is discussed using an example basalt wool. This material has the following characteristics:

  • low thermal conductivity;
  • durability (from 50 years);
  • affordability;
  • preservation of qualities when humidity increases inside the garage;
  • comfort in working with the material;
  • mildew resistance;
  • environmental cleanliness;
  • non-flammability.

Subsequence internal lining walls mineral insulation next:

  1. The location of the sheathing is determined, and the amount of material required is calculated depending on the area of ​​the sheathed surface. For frame would be better suited steel profile, since wood collapses faster when interacting with moisture. Also latest material“leads” when slightly wet.
  2. Vertical guides are installed. The distance between them should be 1-2 cm less than the width of the insulation so that it expands and efficiently takes up space. To strengthen the structure, crossbars are placed horizontally every meter, which here can be wooden.
  3. The installed sheathing is surrounded by a membrane or other waterproofing material. The joints are taped, and the film is attached to the staples (a furniture stapler will do).
  4. The insulation is placed inside the sheathing from bottom to top. There should be no gaps.
  5. Layer vapor barrier material applied on top of the insulation (roofing material or polyethylene film are suitable).
  6. The final stage is covering the sheathing. Performed non-flammable material; An example is steel siding or drywall.

It is important to take into account that when covering the garage from the inside, the space narrows. The insulation should not be too bulky.

When covering with foam plastic, you need to take into account some features of the material. It does not expand like cotton wool, so there is no need to make the distance between the frame guides 1-2 cm smaller. It is better to create the sheathing in blocks, the dimensions of which exactly match the dimensions of the foam. If there are any defects, the walls should be leveled first. It is also advisable to use an L-shaped profile and attach the insulation sheets with glue.

Working with liquid materials will be inconvenient, so it is better to line the top of the garage with foam plastic. The fixation method is similar to that previously discussed, but there is one caveat - you should take care that there are no holes in the roof of the box. If there are any, welding will come to the rescue. As with walls, when insulating the ceiling, a layer of foam plastic is located between the hydro- and vapor barrier layer.

Entrance trim

Wall insulation will not be beneficial if cold air enters through the cracks entrance gate or gates. The situation is easily solved by using rigid insulation such as polystyrene foam. First, the gates are insulated, then the small entrance door to them. The sequence is:

  1. Treated with protective mastic metal surface. Expanded polystyrene is not afraid of moisture, however, when opening the gate, raindrops or snow can get into the cracks between the material and the iron sheet. This should not be allowed.
  2. Attach lathing profiles along the perimeter of the gate.
  3. Fix the polystyrene plates to the mounting adhesive; it is advisable to apply penofol (a foil-based material) on top of them.
  4. Execute wooden sheathing for installation of cladding. Provide a distance of about 30 mm between the future lining/plasterboard/other cladding material and polystyrene foam, so that there is an air gap.
  5. Fix the cladding to the sheathing.
  6. Perform similar actions with the gate.

Floor insulation

Sometimes there is a need to insulate the bottom of the garage. For example, if there are large gaps or the importance of the caisson (cellar). Suitable material will become foam plastic, on top of which a material is applied that prevents its destruction from human movement. Follow these steps:

  1. Level the surface, remove cracks and holes with putty.
  2. Prime the floor twice if it is concrete.
  3. Make lathing from steel profiles.
  4. Apply a layer of waterproofing.
  5. Apply glue, put foam on top of it, press it to the floor.
  6. Screed the floor with a special solution. Extracted granules are added to increase strength.

Carrying out the operations described above will allow you to maintain optimal microclimate inside the garage. Even a beginner can master the process, and the result will be the safety of the car, food or other items of value stored inside the box.

A metal garage is the easiest option to hide your car from bad weather and intruders. Naturally, you need to make it warm to make your stay in the “stall” of your favorite vehicle comfortable. How to insulate an ordinary metal unheated garage? It is now customary to carry out insulation classic materials. Although the construction market is ready to offer a lot of new products that have excellent characteristics in terms of thermal insulation. Therefore, the problem of insulating a metal garage is easy to solve. But let’s look in more detail at how to do it correctly and how to perform insulation.

Advanced car enthusiasts who decide to do it with their own hands prefer to use the following insulator options as materials:

  1. Polyurethane foam. To apply polyurethane foam to the surface, special equipment is required. However, only such material allows for truly high-quality insulation, and for many decades. This The best way achieve your goal.
  2. Penoizol. This is what is called liquid foam. It is also durable, it is not afraid of moisture and high temperatures.
  3. Astratek. Another liquid heat insulator applied with a brush. A millimeter layer of astratek retains as much heat as thick mineral wool. Disadvantage: high consumption (about half a liter per square meter of metal).

Each of the listed materials for garage insulation It is quite effective, but usually the car owner is forced to abandon it due to its high cost. Therefore, much more often a metal garage is insulated using the most available material, namely, polystyrene foam.

Insulation of metal garage walls

Let's look at how to insulate a metal garage from the inside, and do it entirely with your own hands. All work must be performed adhering to a certain scheme. First you need to make a frame, inside of which the insulator slabs will then be laid.

To begin with, you should make sure you have a certain tool. It is impossible to do such a thing as insulating your own garage without a drill, screwdriver, hacksaw, grinder. When everything is collected that is necessary, you can begin the insulation process.

First you need to mount a frame from guides and a profile, using the material that is taken for manufacturing plasterboard partitions. The guides are fastened with dowels, and the profile is secured to them with special hangers.

After garage insulation, it is not necessary to use plasterboard to cover the thermal insulation; asbestos fiber is also suitable for this purpose. The material perfectly resists fire, but is fragile. Because of this, the distance between the posts is required to be slightly smaller.

After completing the installation of the frame, insulation should be placed between the racks. We recommend using a classic heat insulator - glass wool or mineral wool slabs. This material retains heat perfectly and is non-flammable. But a cheaper option, polystyrene foam, is a flammable substance that releases toxic components when ignited. If the step between the racks is made according to the width of the mineral slabs, their installation will be simple and will not require additional adjustment. The final stage of insulation is securing the vapor barrier material with tape and installing the cladding.

Foam plastic is recognized as the cheapest material for insulating the walls of a metal garage from the inside. Before using glue to attach this material, it is necessary to thoroughly clean the internal surfaces of the building from rust and the slightest dirt, then be sure to degrease the metal. This way the fastening will be of better quality. When the foam sheets have already been glued, it is advisable to blow out the cracks between them using a can of polyurethane foam. Next, you can cover the insulation layer with any finishing material.

Insulation of metal garage doors

Having decided to make a high-quality insulation of a metal garage, you should make sure that the gates do not allow cold into the room. Experienced car enthusiasts recommend doing it in the gate leaf front door, then you won’t have to open them completely when entering. In addition, a special curtain should be installed from the inside in front of the gate to prevent heat leakage from the room.

An excellent material for organizing the task at hand is transparent plastic or plastic film (certainly thick). Having cut the selected version of the protective curtain into long strips, they are stapled to a wooden strip fixed above the gate from the inside. Each fixed strip must be one and a half centimeters apart from its neighbor, then when the car leaves, they will deviate and then return back, preventing heat from escaping outside.

However, just a curtain is not enough; the door leaf itself also needs to be insulated protective material. Typically, foam is used for this purpose, which can be fixed to metal using glue.

You can cover the outside of the foam with anything:

  • clapboard;
  • plywood;
  • plastic.

To prevent cold penetration through the gaps around the perimeter of the gate, a rubber seal is used. To prevent condensation from appearing subsequently, it is advisable to treat the metal in the place where the rubber is glued with any anti-corrosion compound.

Ceiling insulation in a metal garage

When solving the problem of how to insulate an iron garage, you should definitely take care of the thermal insulation of the ceiling. It needs to be insulated not only from the inside, but also from the outside. Only then will it be possible to achieve the desired effect. If the outside is traditionally insulated with paint, then there are several ways to work from the inside:

  • multi-layer painting of the ceiling with a heat-insulating agent;
  • spraying liquid heat insulator;
  • the use of mineral wool or polystyrene foam boards.

By selecting last option, as the cheapest, slabs should be fastened bitumen mastic. When using expanded polystyrene, you will additionally have to treat the seams with some kind of sealant. Applying mineral wool, remember that it absorbs moisture, so you need to protect its layer with waterproofing.

At rafter system The design of the roof, its insulation depends entirely on the design. When there is sufficient space between the rafters, insulation boards should be installed between them, and the waterproofing should be fixed on top. It is advisable to carry out such work at the construction stage - it will be easier and better to insulate the room.

If the pitch between the rafters is small, insulation should be laid underneath them. When there is an attic, it is most practical to fill it with expanded clay and then lay waterproofing material on top. The final stage of such insulation is pouring cement screed. However, high-quality thermal insulation interior space this will not be achieved - it is necessary to fulfill and interior work. Here everything depends only on the material that will be used:

  1. Foil polyethylene should be secured with slats directly to the ceiling. This material perfectly repels moisture. To get the maximum effect, you need to nail plywood or fiberboard over the slats.
  2. Mineral wool. First, you need to glue the waterproofing to the ceiling, then install the sheathing. Place mineral wool slabs in its gaps and protect them vapor barrier film and cover it with cladding.
  3. Expanded polystyrene. Glue the slabs to the ceiling using tile adhesive. To improve thermal insulation, it is recommended to first glue a waterproofing sheet to the ceiling.

Floor insulation

Basically, we have dealt with the question of how to insulate a metal garage. It remains to consider additional features protection from the cold. Helps improve thermal insulation. Since its surface is usually made of metal or concrete, we will consider options for insulating these materials.

The most affordable option now is to insulate the floor with foam plastic:

  • First you need to carefully level the surface, then clean it, eliminating all depressions or cracks with putty.
  • When covering a concrete surface, it should first be primed twice.
  • If there is a hole or cellar in the garage, waterproofing is required.
  • Apply glue directly to the floor, as well as to the foam plastic, with a notched trowel, lay the slab and press it carefully.
  • It is allowed to use special dowels, but then you will have to drill the floor.
  • The floor insulation is completed with a screed. Additional strength will be provided by the addition of extruded granules to the solution.

Insulation of a garage cellar

If there is a cellar or inspection hole, they also need to be carefully insulated.

Cellar ceiling

Before insulating the cellar ceiling, install a layer of waterproofing on it. Then you can glue the foam to the ceiling. Perfect option insulation - liquid filler, although its use is much more expensive.

Cellar walls

The material for wall insulation must be mold-resistant and moisture-proof. The best option– expanded polystyrene. Its slabs should be attached to the sheathing or directly to the walls. When performing insulation work, do not forget about the wiring. It must be laid in a metal sleeve or a box must be secured.

Cellar floor

Since the floor in a garage cellar is usually unpaved, it is better to fill it with bitumen. First you should pour crushed stone, then sand, compact everything and pour bitumen on top. If the floor is reinforced concrete, it is better to cover it with roofing felt on top of sawdust, and then fill it with a cement screed on top.

Conclusion

In conclusion, a few tips:

  • If the garage is separate from other buildings, external thermal insulation is also necessary.
  • Insulating flat roof, it is necessary to organize a slope that allows water not to accumulate.

A metal garage is a reliable shelter for a car not only from the encroachment of unscrupulous persons, but also from weather factors unfavorable for this vehicle, such as snow or rain. But a poorly equipped garage made of metal profiles by itself is not able to fully protect the car from the effects of harsh climatic conditions.

The temperature in the garage should be comfortable for the safety of the car, that is, it should be stable, without changes and higher than outside. Such conditions can be achieved in a metal garage by insulating the gates, ceilings and walls.

The two main enemies of a car when it is idle are frost and moisture. Frost can cause corrosion of the car body, cracking of various fuel and oil lines, etc. And moisture is the main cause of rust, mold and similar formations.

Good to know: optimal temperature in the garage it should be in the range from -5 in winter to +25 in summer.

In the summer it is not difficult to influence this indicator - install an air conditioner or a couple of fans and the problem is solved. It's a different matter in winter. Of course, you can install a heating system in the garage. However, this is not always convenient and profitable.

Firstly, this extra costs for electricity or other resources spent on heating. Secondly, the garage is not always located in close proximity to the car owner’s home, and leaving a garage with the heating system on without proper supervision is not always prudent and safe.

The way out of this situation is to insulate a metal garage with your own hands. By insulating the garage, you can, in fact, solve not one, but two problems at once:

  • keep the garage warm in winter;
  • cool in summer.

This is very important, since the summer heat also does not have a very favorable effect on the car.

Before carrying out insulation work, all surfaces must be cleaned of dirt, dust, rust, etc.

It is possible (and even recommended) to treat the metal of the gate, walls and ceiling with anti-corrosion agents, seal all existing cracks and cracks with sealants, and also, if possible, get rid of any irregularities, bulges, etc.

What to insulate

The answer would seem obvious: everything needs to be insulated - the floor, ceiling and walls. However, if everything is very clear with the walls and ceiling, then with the garage floor, not everything is so obvious.

Since a garage is a place to park a car, the floor in this room has its own specifics. Firstly, it is constantly subject to increased mechanical stress. This includes the weight of the car, and the installation of any equipment (various winches, workbenches, boxes for spare parts and tools), and so on. Therefore, insulation must be performed with materials with increased strength. Secondly, quite often quite aggressive substances such as gasoline, various oils, diesel fuel, solvents and others get on the surface of the garage floor. This must also be taken into account when choosing insulation materials, adhesives, sealants, etc.

Note: If your garage has an inspection hole, then the process of insulating the floor becomes quite complicated. In this case, it will not be possible to use a continuous layer of insulation, and you will have to choose: either abandon floor insulation at all, or at the same time insulate and inspection hole. Otherwise, insulation work will not give any tangible effect.

How to insulate

Before you insulate a garage, you need to answer the questions: how to insulate an iron garage from the inside? What's the best way to do this? What material should I use? This will help you find the answer to the question: how to properly insulate your garage?

Let's look at a few of the most suitable materials for these purposes.

Mineral wool. Possessing high thermal insulation properties, this material is very good for insulating a garage. However, mineral wool is very vapor permeable. Therefore, when using mineral wool as insulation, you definitely need to take care of high-quality vapor and waterproofing.

Penoplex. It is highly undesirable to insulate a metal garage from the inside with penoplex. The reason for this is that in the garage work is often carried out with materials, devices and tools that are easily flammable. Penoplex burns well, and is also capable of emitting acrid smoke.

Glass wool. This material costs less than mineral wool and is more fire-resistant than penoplex. However, these indicators are not so good as to make glass wool the optimal insulation for a garage. Glass wool insulation also requires additional hydro- and vapor barrier.

Astratek. Modern liquid insulation, which is applied with a conventional spray gun, like paint. This material is a reliable protection for metal garage walls. The insulation of an iron garage with Astratek is no worse in terms of performance than the thermal insulation of a similar room with a 5-centimeter layer of mineral wool.

Penoizol. This is the same polystyrene foam, only in liquid form. It is durable, waterproof and, unlike conventional polystyrene and penoplex, penoizol is fire resistant. And the cost of this material is lower than that of the same foam.

Polyurethane foam. One of the most reliable and most durable insulation materials. Its service life can last up to 70 years. The only downside to this material is that it is quite high cost, yes, the installation of polyurethane foam requires special equipment.

Each of the above materials has both its pros and cons. Some are cheaper, some are more expensive. Some things are easier to work with, some things are more difficult. There are plenty of options on how to insulate a metal garage from the inside, and much depends on the financial capabilities of the owner, his enthusiasm, taste, and so on.

In this article, we tried to provide basic information on how to insulate a metal garage with your own hands. This will help you get a clear picture of what you will have to face when insulating your garage space. We will provide more detailed information about insulating a garage from a professional metal sheet in other articles from this category.

Owners of apartments and private houses often have a question: how to insulate an iron entrance door? The fact is that even though a metal door is reliable protection from uninvited guests, the material from which it is made is an excellent heat conductor. This, in turn, leads to the structure freezing during the cold season and ice forming on its inside. Let's figure out whether it is possible to insulate an iron door with your own hands, and what is needed for this.

Process high-quality insulation cannot be started without properly selected insulation. Fortunately, on modern market You can easily find what you need. It’s worth saying right away that you can use both hard and soft insulation; the choice depends entirely on you.

According to consumer reviews, one of the popular insulation materials is mineral wool. There are several reasons for this: it is inexpensive, easy to use due to its soft structure, absorbs noise well and has memory, that is, it is able to recover in size after compression. Vata copes well with temperature changes, protecting the house from the cold. The disadvantages include the fact that the material is soft and can settle over time. However, this drawback can be easily mitigated by creating stiffening ribs in the door structure, which do not allow the mineral wool to “slip” over a long period.

One of the most popular insulation materials is mineral wool.

A big problem for mineral wool is exposure to moisture, or rather condensation, which forms when the dew point moves inward door leaf. Stone wool will help to properly insulate an iron door from the inside. It is not susceptible to moisture, so it can be used even for thermal insulation of the entrance doors of private houses. Otherwise, mineral wool is suitable only for apartment doors with a heated vestibule (corridor).

Foam plastic - another one popular way save heat in the room. The material is very light in weight, which eliminates the weight of the door structure. It is durable and wear-resistant. Polystyrene does not require additional waterproofing because it is not hygroscopic. In addition, it does an excellent job of suppressing noise from outside and holds heat well. Choosing among various options, you should give preference to expanded polystyrene, for example, Penoplex. It is much denser than ordinary polystyrene foam, therefore, with a smaller thickness (and this can be very important!) it has the same properties as polystyrene foam bigger size. In addition, it is not recommended to use simple polystyrene foam, since it can release harmful substances when heated.

Corrugated cardboard is the insulation material for almost all doors supplied from China. What can you say about this insulation? The material has weak thermal insulation properties, but very cheap, which makes doors with such insulation accessible to the majority of the population.

Quite expensive, but very effective material used in insulating a metal door is polyurethane foam. It is applied using special tool. Thanks to its “liquid” structure at the application stage, it makes it possible to fill all cavities without exception, forming a solid canvas. The disadvantage of this material is its price, so it has not yet found sufficient distribution among our compatriots.

Also, isolon is not a very cheap thermal insulation material. But big advantage is his minimum thickness. The material is sold in rolls, so you can easily purchase exactly the length you need. Thanks to the adhesive side, it is simply attached to the canvas, and this can be done without even disassembling the entire door structure, although in this case you will have to make overlays on top to hide the insulation. To do this, you can use a sheet of plywood or other material.

It is also worth noting that materials such as, for example, foam rubber can be used to insulate entrance doors. chipboards and others. But, let’s face it, their quality of thermal insulation is almost minimal, in addition, they are highly susceptible to moisture, which also increases their weight iron doors. This negatively affects their service life.

At first glance, it may seem that the process itself is overly labor-intensive and requires special knowledge. In fact, even an inexperienced master can handle the job. Having decided on the insulation material, it is necessary to remove the locks, handles and peephole from the door leaf. After this, you need to dismantle the door leaf and place it on a flat horizontal surface. Of course, you can work without removing the door, but this is extremely inconvenient and not always rational.

Even an inexperienced craftsman can cope with the insulation of a split door

First you need to remove the casing from inside doors. Depending on the model, this may be an armored sheet, or it may be a simple cover made of plywood or other material. Most often, the trim is attached to the door using screws or rivets. If the door has old insulation inside, it must be removed by thoroughly cleaning the entire structure. If there are stiffeners in the internal space, then you need to drill holes in them at intervals of 40–45 cm and fill the cavities through them with polyurethane foam for thermal insulation. The diameter of the holes must correspond to the diameter of the cylinder tube.

At the next stage, if mineral wool or other soft insulation is chosen as thermal insulation, a water barrier is installed over the entire surface using polyethylene. This is not necessary for expanded polystyrene, since it already has good waterproofing qualities. Then the distance between the stiffeners is measured and the thermal insulation is cut with a small allowance. This is done in order to minimize the possibility of voids forming between the door structure and the thermal insulation material.

You can work without removing the door, but this is extremely inconvenient and not always rational

The next step is to lay insulation in the cavity. For better installation It is recommended to fasten with “liquid nails” or polyurethane foam. All contact areas must be additionally filled with polyurethane foam, and, if necessary, a layer of waterproofing must be laid on top. When all these procedures are completed, you can begin attaching the lining. If old material has become unusable, then it needs to be replaced with a new one, but which one is up to you to decide. After this you can install peephole, insert the lock and hang the door on its hinges.

If you have a question about how to insulate an iron Chinese entrance door or any other door that is not removable, then in this case the technique will be slightly different from the above. To begin with, remove the canvas and remove the locks, handles and peephole from it. After this, the door is placed horizontally and installation of the frame and stiffeners from the inside and outside canvases. To do this you need to take wooden block cross section 20*20 mm. Moreover, the thickness can be greater - it all depends on the thickness of the insulation itself. If possible, cook metal carcass, then you can use this method.

To install the frame and stiffeners you need to take a wooden block with a cross section of 20*20 mm

The frame is attached to the surface with self-tapping screws, and all joints with the canvas are coated with polyurethane foam to prevent the ingress of air and moisture. When installing metal structure you can use welding machine. All steps for installing insulation will be similar to those described above. The structure is covered from above fiberboard sheet, hardboard or other material that is securely attached to the door leaf. On final stage it is necessary to make holes for the peephole and door lock and install the door in place. If desired, the surface of the door leaf can be additionally trimmed with leather, leatherette, forged or plastic overlays, etc.

Advice! When attaching the frame or sheathing, use clamps. They will help securely fix the structure, preventing it from moving.

Insulation of metal doors is not only the thermal insulation of the door leaf itself. To effectively retain heat, you need to pay attention to some important points.

For a better fit of the door leaf to the steel frame, it is necessary to use rubber seals

For a better fit of the door leaf to the steel frame, it is necessary to use rubber seals, which will help improve the quality of thermal insulation of the doors. They are sold by the required footage, so before installation you need to measure the perimeter of the door. The seal has an adhesive edge that attaches it to the canvas. To do this, the iron surface is degreased and only after that a rubber tape is glued. It is noteworthy that with a wide door frame You can attach the seal in several layers.

Please note that the tape itself comes in different thicknesses and types. Depending on the size of the gap, you can choose required option. For large gaps, it is recommended to use a sealant in the form of the Latin letters O and D. For gaps ranging in size from 3 to 5 mm, tapes resembling the letters V or P in cross-section are suitable. And you can get rid of very small gaps using a C- or K-shaped seal.

Thermal insulation of the door frame has a great effect in insulation. Since its dismantling, insulation and subsequent installation is too complicated a process, you can use the above method, which is used to insulate stiffeners. To do this, you only need a metal drill and foam.

It is important to take into account that when a one-piece door is insulated, its thickness increases, so the possibility of making an extended key should be provided so that the door can be opened without problems. The same applies to the snap-on square on the handle.

In particularly harsh climatic conditions it is advisable to install in doorway heating cable, which is used to install heated floors. To do this, plaster is knocked off the slopes, tile adhesive is placed into the formed cavities, and the cable is mounted inside. In addition, the heating cable is also laid on the floor in front of the door. This system eliminates the formation of cold bridges, which, in turn, reduces the likelihood of condensation forming on the surface of the door leaf, and, therefore, icing.

Now you have an idea how to insulate metal door and you can do all the work yourself. High-quality thermal insulation will not only help keep your home warm, but will also save the door from premature failure, rust and ice formation. Do-it-yourself work will help you save money and fill your home with warmth and quiet.

  • Garage walls, as a rule, have a small thickness, so they cannot perform protective functions when low temperatures and cold wind.
  • In addition, it makes no sense to heat a metal garage, because no matter how much you heat it, the room will still not warm up, but there is a possibility of condensation.

Therefore, insulating a garage is a non-negotiable issue.

When insulating a metal garage, the main thing is not to overdo it. After all, what is comfortable for a person is not always suitable for a vehicle. Therefore, the garage should not be too hot.

The car, after entering a warm room from the cold, is instantly covered with condensation, which has a destructive effect on the body. So thoughtless heating of the garage will not bring any benefit - it will only do harm.

The insulation of the room should be carried out in such a way that vehicle was in the room at a positive temperature, and the temperature in the room should not have much difference with the temperature outside.

The ideal temperature for storing a car in a garage is 5˚C. At the same time, if the car owner is cold, you can use a heating device.

How to properly finish an iron room?

When planning to insulate a garage, you first need to decide on the type of insulation. Today, two methods of insulation are popular:

  1. internal;
  2. external

When insulating internally, not only the walls must be insulated, but also the floor, roof, and gates. There are several varieties for this thermal insulation materials. The choice of material directly depends on the method of fastening.

Most often for internal insulation garage are used:

  • mineral wool;
  • Styrofoam;
  • liquid insulation.

Monawata has high level thermal insulation, but it has one serious drawback - vapor permeability, which can disrupt the structure of the insulation and nullify all efforts.

If it has been decided to insulate the garage using mineral wool, then it is necessary to perform certain operations to install vapor and waterproofing equipment.

Insulation with mineral wool is carried out in the following sequence:

IMPORTANT! If the plans include roof insulation, then it is recommended to leave the finishing until the completion of the insulation equipment work.

Foam plastic is in no way inferior to mineral wool in terms of characteristics. But it is not recommended to use it in rooms where work with flammable materials and flammable equipment is planned, because when the foam ignites, caustic smoke is released.

For those who do not experience financial difficulties, it is recommended to use liquid materials, such as penoizol and polyurethane foam, which fill the space between the sheathing posts.

DIY floor

When choosing a material for floor insulation, it is recommended to proceed from the type of material. Usually, In garages, floors are made of metal or cement screed. Consequently, insulation must be selected taking into account the properties of these particular materials.

The floor is the main fire hazard in the garage, so it is strictly forbidden to use materials with low fire safety. Of the materials offered on the construction market, it is recommended to give preference to foam plastic. And done correctly finishing will allow you to hide the insulation from fire.

  1. Floor insulation begins with cleaning and leveling the base surface. If there are cracks on the floor and chips need to be repaired with mortar, the bulges are cut off and cleaned with construction mesh.
  2. The concrete screed must be treated twice with a deep penetration primer.
  3. At the next stage, a layer of floor waterproofing is created, especially if the garage is equipped with a cellar or inspection pit.
  4. Then apply to the surface of the screed using a notched trowel. adhesive composition, foam plastic slabs are laid on it and tightly attached to the base.

    REFERENCE! In some cases, foam plastic can be fixed with dowels, but for this you need to prepare the holes in advance.

  5. At the final stage, a new screed is poured, into which special granules are added to ensure the strength of the surface.

Gates

Garage doors typically take up one third of the garage's perimeter. That is why, without their high-quality insulation, the thermal insulation of the entire room will be minimal, therefore, when installing thermal insulation for the gates, it is necessary to hide all the cracks and prevent severe freezing.

Taking into account the fact that the gate has a wicket, its insulation must be carried out separately.

Walls from the inside

The walls of an ordinary metal “box” should be insulated from the inside. Foam plastic is most often used in sheets or rolls. This material has increased level thermal insulation. It is attached to the walls using special glue.

Insulation using polystyrene foam is an effective, yet fairly cheap method. Installation of polystyrene foam is carried out using the same technology as floor insulation: first, lathing is made, then thermal insulation is laid and covered with cladding.

Roof

The roof, like the walls, is most often insulated using polystyrene foam. If you use mineral wool as thermal insulation, it is fastened with a stapler and hidden under a “false ceiling”.

ATTENTION! The foam is fixed with glue. This is explained by the fact that with another installation method it will be necessary to make several holes in the roof, and this is unacceptable.

Conclusion

Properly equipped garage insulation will make it possible not only to protect the vehicle from rust and premature failure of its systems, but also to independently carry out technical inspection and minor repairs even in the cold season.
