The organization of the correct storage of the car is the key to its long service life, reducing overhead costs for repairs. The temperature in the garage during the cold season should be about +5 ° С. Higher values will lead to the formation of condensation, premature metal corrosion, while lower values will cause difficulties in starting the engine.
Due to freezing of the soil, the floor becomes the main direction of heat loss. If it is concrete, the room gets colder many times faster. Warming the floor in the garage will help to solve the problem. And how to do it correctly, we will consider in detail in this material.

Features of thermal insulation of the garage floor
The easiest way to insulate the floor of a room is to install heat-insulating materials during the construction process. The choice of heaters, the list of works should be agreed at the design stage.
If the garage is actively used and a decision was made on additional thermal insulation, it will be somewhat more difficult to implement the plan.
The need to insulate the garage floor is due to the requirements for car storage. To ensure the operability of the car and extend its service life, to minimize repair costs, it is important to maintain the air temperature in the garage at +5 ° C.
When planning the insulation of the garage floor, it is worth considering that difficulties may arise in the process of carrying out the work, including:
- Choice of materials. A huge variety of heaters on the market makes it possible to solve a problem of any complexity. However, it can be difficult to make a choice on your own. Before buying, study the types of heaters, their performance.
- The order of work. Insulating a garage does not require deep specialized knowledge or the presence of expensive professional tools. However, the technology for working with wood and concrete floors is different.
- Price. At first glance, it seems that garage insulation will not require serious investments. In practice, car owners do not always manage to take into account all costs. So that the work on warming the garage floor does not stop, it is worth purchasing all the necessary materials before starting.
When planning to do the insulation of the garage floor, it is important to first study the theoretical material, plan all the stages, buy materials, and only then get down to business.
Types of materials for insulation
The labor intensity of the work and their cost depend on the choice of material for insulation. In order not to be mistaken when buying, it is worth studying their types, performance characteristics.
Today, it is not difficult to purchase material for floor insulation. In order to choose the best option for a particular garage, it is important to understand what properties the heaters have
Different requirements are imposed on the materials that must ensure the preservation of heat in the garage.
The main criteria for choosing insulation for walls and floors in a room include:
- Reliability. The material should not only prevent heat leakage, but also be resistant to humidity and temperature extremes.
- Security. The insulation should be resistant to fire, or better not to support combustion at all.
- Vapor permeability - assumes unhindered air exchange, which allows you to maintain an optimal level of humidity in the garage.
- Strength. The long service life of the material will allow you to enjoy the results of your labor for many years without the need for repairs.
- Insulation characteristics. High-quality insulation will not only prevent the cold from penetrating, but will also increase sound insulation.
An important selection criterion is ease of installation. When choosing insulation, pay attention to whether you can lay it yourself. To choose the right insulating material, study the manufacturers' proposals, understand their characteristics.
Option # 1 - expanded polystyrene
This synthetic material has been successfully used for thermal insulation of various surfaces, including floors. It is perfect for insulating a wooden or concrete floor in a garage.
Expanded polystyrene has become an excellent solution for premises for various purposes. It retains heat well, has a low weight, and is easy to install. The only negative is the release of acrid smoke during combustion.
If it is necessary to insulate a wooden structure, the sheets are stacked between the logs, covered with thick sheets of plywood. For concrete insulation, the foam is fully laid out on the base, filled with mortar.
The advantages of the material include:
- High strength - the insignificant mass of insulation sheets does not prevent it from withstanding serious loads.
- Light weight - low weight provides ease of transportation, stacking of material.
- Moisture resistance - foam panels are resistant to moisture, they do not absorb it, losing their original properties, do not rot.
Expanded polystyrene refers to budget solutions. Its use will allow you to insulate the garage floor at minimal cost.
Option # 2 - extruded polystyrene foam
The extruded material differs from the traditional manufacturing technology, the presence of additives in the composition. The result is a material with a foam structure for improved performance.
The use of an extruder makes it possible to obtain a material with increased thermal insulation characteristics. However, high efficiency also has disadvantages - the extruded foam burns perfectly, does not allow air to pass through.
Extruded polystyrene foam can be equipped with foil protection. This option will be an ideal solution for insulating the garage floor. The presence of the film will provide an additional barrier to cold, protect the material from moisture. Insulation is produced in slabs, rolls, sheets of different thicknesses.
The use of EPS provides additional advantages:
- Hygroscopicity - the foil completely covers the cellular structure of the insulation, so it cannot absorb moisture. This property is relevant when insulating a garage with wooden floors.
- Chemical resistance - the level of water and soil pollution is quite high. The use of foil-clad heaters will extend the life of the material even when they come into contact with acids, alkalis, and other aggressive substances.
- Strength - a special structure, reinforced with a foil layer, allows the extruded polystyrene foam to withstand high loads without deformation.
It is easier to lay polystyrene foam in rolls on a concrete floor. For wood flooring, slabs will be the best solution.
Before starting work, we recommend that you familiarize yourself in more detail with the features and rules for working with EPS.
Option # 3 - penoizol
The material is called liquid foam. It will become a practical solution during the construction, reconstruction of the garage.
The key advantage of penoizol is its liquid form. During application, the material fills all the gaps, eliminating the likelihood of cold bridges after the end of the work
Due to its liquid form, Penoizol provides an absolutely hermetic coating of the entire surface. Its use eliminates the possibility of crevice formation.
Option # 4 - expanded clay backfill
The material is relatively inexpensive and easy to handle during installation. Clay raw materials, which remain in the process of pottery and brick factories, do not burn, are not afraid of temperature extremes, and retains heat well.
Expanded clay makes minimum requirements for the qualifications of the installer during the insulation of the garage floor. Small clay balls are characterized by low weight, excellent thermal insulation, fire resistance
Expanded clay is laid in two ways. The dry method involves filling the material between the logs of the wooden floor. Wet - adding expanded clay to the concrete solution.
Material pluses:
- high sound and heat insulation;
- easy to work with;
- does not burn, does not emit acrid smoke;
- not afraid of frost, temperature changes.
Expanded clay is a budget option that is acceptable for most premises. The only drawback is the active absorption of moisture, therefore, when arranging the floor, it is important to provide waterproofing.
Option # 5 - mineral wool
Classic insulation is versatile, so it is perfect for a garage floor. The material is sold in the form of mats or rolls of various thicknesses, so choosing the best solution is not difficult.
Mineral wool is characterized by high performance and ease of installation. A variety of design options allows you to choose the optimal solution for each specific case
Manufacturers offer glass, basalt, stone and slag wool. Materials differ in the type of raw materials used, operational characteristics.
However, the general benefits include the following:
- Low thermal conductivity, the ability to retain heat without giving it away.
- Mineral fibers are excellent at absorbing sound, providing soundproofing of the room.
- Resistance to damage - the material is recommended for use in wooden structures in which mice can settle. Rodents don't like this stuff. In addition, mineral wool is resistant to mold and mildew.
- Excellent air exchange - mineral wool is excellent for air permeability.
- Durability - the material does not lose its performance for a long time, retaining heat for many years.
The ability to select individual slabs or rolls simplifies the process of insulating your garage floor.
Floor insulation instructions
There are a lot of options to insulate the floor in the garage. In most cases, the method that is chosen depends on the type of floor.
It is recommended to install the insulation in the warm season - it will be easier to work, and the screed can harden faster.
Starting work on floor insulation, it is important to take into account the base material, your own professional skills, the size of the budget
The insulation plan depends on different criteria. The main ones are: training, available budget, selected materials.
Insulation of a wooden garage floor
The most budgetary solution is the use of mineral wool. The material is inexpensive, and installation does not require professional skills or expensive tools.
The order of work is as follows:
- level the soil, pour a layer of sand up to 10 cm thick on it;
- fill in the concrete screed;
- lay a layer of waterproofing using polyethylene, roofing felt;
- install wooden logs so that the distance between them corresponds to the width of the insulation roll;
- lay mineral wool in the recesses;
- cover the insulation with a layer of waterproofing;
- lay the wood flooring.
Wooden logs can be installed on a base made of expanded clay. Often, foam or extruded polystyrene foam is used instead of mineral wool.
Thermal insulation of a wooden floor is reduced to providing waterproofing, filling the space between the joists with an insulating material. When cold protection is installed during the construction phase, the joists are mounted on an insulated base.
The thickness of the insulating layer or sheets of material should be about 10 cm. If work is carried out in a finished garage, the insulation is reduced to filling the space between the logs with a heat insulator, ensuring its protection from moisture.
You have not only a garage, but also a wooden floor in your house? And you also thought about its insulation? We recommend that you familiarize yourself with technology of work for thermal insulation.
Working with a concrete base
Stronger concrete floors are preferred by owners of heavy vehicles. A high-quality screed guarantees long-term use of the surface. In the event of cracks or insufficient insulation, an additional layer of insulating material can be laid on top of the old one, without dismantling.
To create an insulating layer, all the same materials are used, only the rules for their laying are changed. Expanded clay is poured onto the rough base with a layer of 25 cm, covered with a reinforcing mesh, and poured with mortar.
When using expanded polystyrene, most of the load will be on the foam layer.
To ensure the durability of the structure, you must adhere to the following recommendations:
- When preparing the base, carefully seal up all irregularities that can break the insulation layer.
- Overlap the waterproofing film, do not forget about entering walls up to 15 cm high. Secure the joints with tape.
- Lay the foam sheets tightly, secure the joints with glue or polyurethane foam.
A film is laid on the insulation layer, which will prevent the penetration of moisture from the solution, then a reinforcing mesh. The structure is filled with mortar.
Insulating the floor with expanded polystyrene is a simple, practical option for a garage. To create a monolithic structure, the sheets are sometimes equipped with spikes and grooves or chamfers.
If necessary, heating the garage is installed in some cases water heated floor. Foil polystyrene foam is then used as a heater.
The design additionally integrates pipesthrough which the coolant circulates to provide heating.
We reviewed the best ways to heat a garage in next article.
When planning floor insulation in the garage, it is worth considering an inspection pit - its presence facilitates maintenance and repair of the car. However, it becomes a serious heat leakage channel. When working with the floor, do not forget about its thermal insulation.
The complexity of the device of modern machines leads to the fact that the owners are less and less likely to independently carry out various works, so the pits are not used for their intended purpose. As a result, they are closed with homemade plugs, warming with improvised materials. If there is a difference in the quality of the thermal insulation of the floor and the pit, condensation may form in the place of the temperature difference.
