The organization of proper storage of the car is the key to its long service life, reducing overhead costs for repairs. The temperature in the garage in the cold season should be about +5 ° C. Higher values will cause condensation, premature corrosion of the metal, and low 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 colds many times faster. Insulation of the floor in the garage will help to solve the problem. And how to do this correctly, we will consider in detail in this material. Having studied the information below, you will understand the types of insulation, study the step-by-step instructions for conducting independent work.
Features of thermal insulation of the garage floor
The easiest option to warm the floor of a room is to lay insulating materials during the construction process. The choice of heaters, the list of works should be agreed upon 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 for insulation of the garage floor is determined by the requirements for car storage. To ensure the operability of the machine 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 in the process of carrying out work, difficulties may arise, including:
- Material selection. A huge variety of heaters on the market provides the opportunity to solve the problem of any complexity. However, making your own choices is not easy. Before buying, study the types of insulation, their operational characteristics.
- The order of work. Garage insulation does not require deep specialized knowledge or the availability of expensive professional tools. However, the technology for working with wooden and concrete floors is different.
- Cost. At first glance, it seems that the insulation of the garage does not require serious investments. In practice, car owners are not always able to take into account all the costs. So that the work on warming the garage floor does not stop, it is worthwhile to purchase all the necessary materials.
When planning to do 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 complexity of the work, their cost, depends on the choice of material for insulation. In order not to make a mistake when buying, it is worth exploring their types, operational 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 heaters have
The materials that must ensure the safety of heat in the garage have different requirements.
The main criteria for choosing insulation for walls and floor in the room should include:
- Reliability. The material should not only prevent heat leakage, but also be resistant to moisture, temperature extremes.
- Safety. The insulation should be resistant to fire, and 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 life of the material will allow you to enjoy the results of their labor for many years without the need for repair.
- Insulation characteristics. High-quality insulation will not only prevent the penetration of the cold, but will also increase sound insulation.
An important selection criterion is ease of installation. When choosing a heater, pay attention to whether you can lay it yourself. To choose the right insulation material, study the proposals of manufacturers, 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 warming a wooden or concrete floor in a garage.
Expanded polystyrene has become an excellent solution for rooms for various purposes. It perfectly retains heat, has a low weight, easy styling. The only minus is the emission of caustic smoke during combustion
If necessary, to isolate the wooden structure, the sheets are stacked between the logs, covered with thick sheets of plywood. To insulate concrete, the foam is fully decomposed onto the base, poured with mortar.
The advantages of the material include:
- High strength - a small mass of insulation sheets does not prevent it from withstanding severe loads.
- Light weight - low weight provides ease of transportation, material laying.
- 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 decisions. Its use will allow insulating the floor of the garage with minimal cost.
Option # 2 - extruded polystyrene foam
Extruded material differs from traditional manufacturing technology, the presence of additives. The result is a material with a foamed structure, improved performance.
Using an extruder allows you to get a material with high thermal insulation characteristics. However, there are also disadvantages to high efficiency - extruded polystyrene burns perfectly, does not allow air
Extruded polystyrene foam can be equipped with foil protection. This option will be an ideal solution for insulation of the garage floor. The presence of a film will provide an additional barrier to cold, protect the material from moisture. Insulation is available in plates, rolls, sheets of different thicknesses.
The use of EPSP provides additional advantages:
- Hygroscopicity - the foil completely overlaps the cellular structure of the insulation, so it cannot absorb moisture. This property is relevant for the insulation of a garage with wooden floors.
- Chemical stability - the level of water pollution, the soil is quite high. The use of foil insulation will extend the life of the material, even when they come in 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 expanded polystyrene in rolls on a concrete floor. For a wooden coating, the plates will be the best solution.
Before starting work, we recommend that you familiarize yourself with the features and rules of working with EPSS in more detail.
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 cracks, eliminating the likelihood of cold bridges after work
Due to its liquid form, penoizol provides an absolutely hermetic coating of the entire surface. Its use eliminates the possibility of crevices.
Option # 4 - expanded clay backfill
The material is relatively inexpensive, it is easy to manage with it during installation. Clay raw materials, which remain during the operation of pottery, brick factories, do not burn, are not afraid of temperature changes, and retain heat perfectly.
Expanded clay makes the minimum qualification requirements for the installer during the insulation of the garage floor. Small clay balls are characterized by low weight, excellent thermal insulation, resistance to fire
Expanded clay laying is carried out in two ways. The dry method involves falling asleep material between the logs of the wooden floor. Wet - the addition of expanded clay to a concrete solution.
Material advantages:
- high sound and heat insulation;
- easy to use;
- does not burn, does not emit caustic smoke;
- not afraid of frost, temperature changes.
Expanded clay - a budget option, acceptable for most rooms. The only negative is the active absorption of moisture, so it is important to ensure waterproofing when installing the floor.
Option # 5 - mineral wool
The classic insulation is versatile, so it is perfect for the floor in the garage. The material is sold in the form of mats or rolls of various thicknesses, so choosing the optimal solution is not difficult.
Mineral wool is characterized by high performance and ease of installation. A variety of options allows you to choose the best 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 following are common benefits:
- Low thermal conductivity, the ability to retain heat without giving it away.
- Mineral fibers perfectly absorb sound, providing soundproofing.
- Resistance to damage - the material is recommended for use in wooden structures in which mice can settle. Rodents do not like this stuff. In addition, mineral wool is resistant to mold and mildew.
- Excellent air exchange - mineral wool perfectly passes air.
- Durability - the material does not lose its operational characteristics for a long time, retaining heat for many years.
The ability to select individual slabs or rolls allows you to simplify the process of warming the floor in the garage.
Floor Insulation Instructions
There are a lot of options to insulate the floor in the garage. In most cases, the method that is selected depends on the type of floor.
Installation of insulation is recommended in the warm season - it will be easier to work, and the screed can harden faster.
When starting work on floor insulation, it is important to consider the base material, your own professional skills, and the size of the budget
The plan for the insulation depends on various criteria. The main ones: training, available budget, selected materials.
Garage wooden floor insulation
The most budgetary decision is the use of mineral wool. The material is inexpensive, and installation does not require professional skills, expensive tools.
The procedure for the work is as follows:
- level the soil, pour a layer of sand on it up to 10 cm thick;
- pour in concrete screed;
- lay a waterproofing layer using polyethylene, ruberoid;
- 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.
Warming of a wooden floor is reduced to providing waterproofing, filling the space between the logs with insulating material.When protection against cold is established at the construction stage, the logs are mounted on an insulated base
The thickness of the insulating layer or sheets of material should be about 10 cm. If the work is done in the finished garage, insulation is reduced to filling the space between the lags with a heat insulator, ensuring its protection from moisture.
Do you have not only a garage, but also a wooden floor in the house? And you also thought about its insulation? We recommend that you familiarize yourself with the technology of thermal insulation work in more detail.
Concrete work
Stronger concrete floors are preferred by owners of heavy vehicles. High-quality screed ensures long-term operation of the surface. In the event of cracks or insufficient insulation, it is possible to lay an additional layer of insulating material on top of the old one without dismantling.
To create an insulating layer, all the same materials are used, only the rules for their installation are changed. Expanded clay is poured onto a rough base with a layer of 25 cm or more, covered with a reinforcing mesh, and poured with a solution.
When using polystyrene foam, 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 repair all irregularities that can violate the insulation layer.
- Overlap the waterproofing film, do not forget about approaching the walls up to 15 cm high. Fix the joints with tape.
- Fold the foam sheets tightly, fix the joints with glue or polyurethane foam.
A film is placed on the insulation layer, which will prevent the penetration of moisture from the solution, then the reinforcing mesh. The design is poured with mortar.
Insulation of the floor with polystyrene foam 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 it is necessary to heat the garage in some cases, a water heated floor is installed. As a heater then foil polystyrene foam is used.
Pipes are additionally integrated into the design, through which the coolant circulates, providing heating.
The best ways to heat the garage we covered in the next article.
When planning floor insulation in a garage, it is worth considering an inspection hole - its presence facilitates maintenance and car repair. However, it becomes a serious channel for heat leakage. Performing work with the floor, do not forget about its thermal insulation.
The complexity of the device of modern machines leads to the fact that owners are less and less independently carrying 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 thermal insulation of the floor and the pit, condensation may form at the point of temperature difference.
You can insulate the floor in the garage yourself. A selection of videos will help to understand in detail the order of the work.
