A metal garage does a lot of things 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 iron garage from the inside to effectively retain heat.
The temperature inside a metal garage can significantly increase traditional materials and new items, the quality of which is tested only by a few. Examples good insulation materials are:
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.
It is advisable to insulate the garage in the warm season, but sometimes the situation forces you to carry out work at sub-zero temperatures. Here there is a need to insulate the box quickly and reliably. To use time efficiently, the following equipment is prepared in advance:
If the above is present, it’s time to start insulating the garage from the inside.
For internal lining metal structures First of all, you need to take care of anti-corrosion treatment. To do this, use a metal brush to remove 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 metal garage for a long time if the surface is treated? Second important factor provision comfortable conditions inside the garage is to create 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 supporting structure of the 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.
The process is discussed using an example basalt wool. This material has the following characteristics:
Subsequence internal lining walls mineral insulation next:
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 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.
Wall insulation will not be beneficial if cold air will flow through the cracks of the entrance gate or wicket. The situation is easily solved by using rigid insulation such as polystyrene foam. First the gates are insulated, then a small Entrance door in them. The sequence is:
Sometimes there is a need to insulate the bottom of the garage. For example, if there is large cracks 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:
Carrying out the operations described above will allow you to maintain an 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.
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 being hit warm room from frost, it instantly becomes 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 the vehicle is in the room at a positive temperature, and the temperature in the room should not have a big 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.
When planning to insulate a garage, you first need to decide on the type of insulation. Today, two methods of insulation are popular:
When insulating internally, not only the walls must be insulated, but also the floor, roof, and gates. For this purpose, there are several types of thermal insulation materials. The choice of material directly depends on the method of fastening.
Most often for internal insulation garage are used:
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.
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 those offered on construction market It is recommended to give preference to foam materials. And done correctly finishing will allow you to hide the insulation from fire.
REFERENCE! In some cases, foam plastic can be fixed with dowels, but for this you need to prepare the holes in advance.
Garage doors typically take up one third of the garage's perimeter. That's why without them high-quality insulation The thermal insulation of the entire room will be minimal, therefore, when installing thermal insulation for the gate, 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.
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 an increased level of 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.
The roof, like the walls, is most often insulated using polystyrene foam. If used as thermal insulation mineral wool, it is secured 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.

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 implement technical inspection And minor repairs even in the cold season.
How to insulate an iron garage from the inside - this question worries owners of homemade products and models industrial production. The structures are more cost-effective 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.
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:
Let's look in detail at how to insulate a metal garage from the inside with your own hands using a democratic option.
The process is divided into several stages.
Before starting the main work, several preparatory operations are performed:
Important! Before you insulate your metal garage, think about ways to save money. Will help you save a lot on your purchase Supplies 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?
We insulate an iron garage according to the following scheme:
Do-it-yourself insulation of a metal garage from the inside is finished. Completing the full cycle of work will not require much time, thanks to large size slabs and ease of fastening to the wall. It will take more time to 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. Other 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 in your steel box there will always be comfortable temperature both in winter and in summer.
The metal garage freezes very much in winter. As a result, the car is difficult to start, and renovation work due to the low temperature in the room, it is completely impossible. Exist different ways insulation of a metal garage, but not all known materials suitable for this. When choosing insulation, it is important to consider what load the installation will place on the garage structure, as well as how many centimeters the internal area will decrease.
The process of insulating a garage depends on the chosen thermal insulation material. In some cases, installation involves additional costs for lathing and finishing; in some cases, insulation is simply applied to the walls. Since the garage is made of iron, it heats up in the sun and collects condensation well. Therefore, materials should be chosen that are most moisture resistant.
For example, mineral wool is not suitable in this case. It will begin to rot, and the insulation will have to be replaced pretty soon.
The following materials are ideal as insulation for an iron garage:
Styrofoam durable, resistant to moisture, it is cheap to insulate, but has high flammability. Penoplex is a variety of it. It is twice as expensive, but the slabs are thinner if the thickness of the walls is important, and also does not require additional waterproofing. Penoplex slabs can even be used to insulate the floor, making concrete screed right on it.
Penoizol Essentially the same penoplex, only in a cylinder. It is twice as expensive and requires special equipment. It is applied to walls in the form of foam, like polyurethane foam. Polyurethane foam (PPU) is more expensive, but there are no seams. Environmentally safe, non-flammable.
Disadvantages include the need for equipment to spray foam and vulnerability to sunlight.
Thermal insulation paints do not require additional wall finishing, since they are also a finishing coating. They are frost-resistant, not afraid of moisture, and can be applied quickly. A 1 mm layer of paint can replace 5 cm of mineral wool. To create the necessary thermal insulation, it is enough to apply two layers. This material is very expensive, but it does not take up useful internal space.
Not only the walls and ceiling, but also the floor should be insulated. It is through it that 20% of the heat escapes.
The insulation of iron garages itself is carried out exclusively from the inside.
Before insulation, the surface must be prepared. Remove peeling paint and clean off rust. It is recommended to paint the walls and ceiling to protect them from corrosion. The color and choice of paint is not important; it will still not be visible under the trim. Therefore, you can save money and buy something inexpensive. If the garage is made of galvanized profile, then nothing needs to be done.
If the region has frosty winters, then the thickness of the foam should be at least 10 cm, penoplex - 6-7 cm. A thinner layer will not provide the required thermal insulation. The material is glued to the walls and ceiling using construction adhesive, e.g. liquid nails. Can also be glued to polyurethane foam. It will expand within an hour, so the slabs should be periodically pressed against the walls. All cracks are sealed with polyurethane foam. To increase the thermal insulation properties, foil can be glued to the slabs.
If you get two layers of polystyrene foam, then one of them can be replaced with double-sided foil-coated isolon.
Next you need to make the sheathing. You can use an existing one as a frame. metal carcass garage. The lathing is made of wood in increments of 25–30 cm. You can use a galvanized profile, but then it will be more expensive. Under no circumstances should the insulation protrude beyond the sheathing. As finishing you can use lining, plywood, moisture resistant drywall, OSB panels or plastic siding. Gates and doors are insulated in the same way as walls.
The surface of the garage walls must also be prepared, Special attention to oil stains - there should not be any. The air temperature in the garage should be at least 10 degrees Celsius. Both the walls and the ceiling are insulated. Polyurethane foam is sprayed using special equipment under pressure, somewhat reminiscent of the painting process. The components are mixed and at the output they give the very reaction due to which foam is formed. The material hardens very quickly. The difference between polyurethane foam and penoplex is that it gives additional rigidity to the structure, no glue is required. The thickness of the formed foam should be 3–4 cm. For comparison, this replaces 5 cm of mineral wool.
Another advantage of polyurethane foam is that it does not require lathing. The top can be covered with paint or plaster. High price PPU is compensated by savings on glue, lathing and facing material, not to mention the thickness of the walls and the load of the structure.
It is impossible to leave polyurethane foam without lining, because Sun rays have a destructive effect on him.
“Astarek” paint is a mastic that can be applied with a brush or spray. After drying, an elastic coating is formed. The paint simultaneously acts as insulation, is used for waterproofing, and has anti-corrosion properties.
A great option for shell garages. For example, it is quite difficult to insulate corrugated material with slabs; construction is required additional frame. All this will take even more usable area the buildings. Application process thermal insulation paint the same as normal. The surface needs to be prepared. Apply a layer of 1 mm, the second layer only after the previous one has completely dried. Two layers are enough for insulation. The paint can be applied to walls, ceilings and gates. It does not place any additional load on the structure of the building.
Material consumption per 1 sq. m is 0.5 liters of paint. Due to its cost, the total cost of insulating the garage will be significant. But you can insulate it from the inside with your own hands, without resorting to outside help. All work is carried out quickly, without reducing the total volume of space. Saving others building materials, for example, the absence of glue, sheathing and cladding. The paint itself is the finishing coat.
It is not afraid of moisture, the walls can be washed and shelves can be attached. With Astratek paint you can insulate a garage not only from the inside, but also from the outside, which other types of insulation cannot boast of.
Some garages have a basement, cellar or inspection hole. It would be a good idea to insulate them too. Due to the limited area, it is inconvenient to use mineral wool or polystyrene foam. Therefore, it is worth paying attention to materials that require the construction of additional structures. For example, walls can be insulated with polyurethane foam and Astratek paint. These materials do not require additional waterproofing, which is very important in such rooms. But the polyurethane foam will need to be painted.
Another option is warm plaster. This is expanded vermiculite or polystyrene foam granules. This insulation at the same time it is a finishing coating, but the walls must be pre-plastered. Expanded clay can be poured onto the floor in a fraction of 5 to 20 mm. A larger option will shrink. The thickness of the coating should be about 10 cm.
You can also fill the floor with crushed stone (10 cm), sand on top (a soft layer) and fill it with bitumen on top.
If the floor is earthen, then it can also be insulated. To do this you need to remove upper layer 15 cm of soil. Next, add a layer of sand or expanded clay. This is necessary for drainage, so that moisture does not accumulate under the insulation, and at the same time it will help level the surface.
Next, foam boards are laid. Sufficient thickness is 5 cm. For of this material no additional waterproofing required. Next, sand 3–4 cm thick is poured onto the insulation. On top of the structure it is necessary to mount a frame made of reinforcement in two layers of 1 cm each. It is necessary for screeding. Fill cement mortar and let dry.
Instead of a screed, you can put a tongue and groove board. To do this, place on the drainage wooden joists in increments of 30–40 cm, between them is polystyrene foam or polystyrene foam. All cracks must be sealed with foam. Attach boards to the top of the joists. As finishing coating You can put linoleum. It is better to start any insulation of the garage from the floor.
Otherwise, doing all the work without damaging the wall decoration will be problematic and inconvenient.
Perhaps every car owner knows that the most optimal temperature, in which the car should be located in winter time should not be lower than -5º C. For owners of a separate permanent building, this problem is not so acute, since, for example, cinder block walls themselves act as insulation, but those who have a metal shell garage have to deal with the problem of cold indoors decide. In this regard, answering the question of how to insulate an iron garage is quite a priority task. What ways to solve the problem exist, and what are the features of the work will be discussed further.
First of all, it is necessary to decide why exactly insulation should be carried out, since the amount of work performed will depend on the understanding of this issue.
So, you can’t do without insulating a metal garage, but how to do it? And in fact there are a considerable number of options. Some are more suitable, some less, but we can highlight some that are the most universal in most cases.
It should be noted right away that, by and large, three methods of insulation can be distinguished.
Each of the methods can be considered separately.
Insulating a garage made of metal is not so difficult. For example, one of the most optimal options The work will be done by gluing foam boards to the walls and ceiling.
Note! It is better to carry out work in warm time year or preheat the room using a heat gun.
Before pasting, the walls must be washed, dried and degreased. The plates are glued tightly to each other, and the joints are blown with foam and taped with construction tape. It should be added that this option will solve the problem of insulation, but will be extremely unstable to external influences, which means that after insulation the walls need to be additionally finished with some more durable material.
You can do it a little differently, and first equip the surfaces of the garage with a special sheathing, and place insulation, for example, mineral wool, in the resulting cells. After which all this is sheathed with the same metal profile. The result is something like a sandwich panel, which is a very effective option.
Note! This insulation method is also suitable for insulating the garage from the outside. However, it should be taken into account that usually the “shells” are located quite tightly, and therefore insulation from the outside may be impossible.
Note! One of the insulation options is to combine internal and external insulation, but it is not always possible to implement, although it is the most optimal.
Insulation of gates and floors
In addition to the above, we can add that when insulating a garage, special attention should be paid to the places, so to speak, of the greatest risk. As you might guess, such places are the garage door, as well as the floor of the room. The gate can be insulated according to the same principle as the rest of the surfaces of the room, but with the floor everything is somewhat more complicated. If the floor is metal, then there is little that can be done, but if the floor is concrete, then you can, for example, lay a layer of insulation and make a concrete screed on top of it.
In conclusion, we can add that there are quite a lot of options for completing the task of insulating a metal garage. You can get acquainted with them by watching a video on the mentioned topic. However, you need to understand that the main key to successful completion of work is a responsible approach to it, as well as the use of high-quality materials and compliance with installation technologies. At the same time, we should not forget about compliance with safety regulations.
