Insulation of the floor in the garage in the country


Many people consider the insulation of the floor in the garage an optional process, but it is through it that a huge amount of cold in the winter and autumn enters the room. Therefore, we decided to insulate not only the walls, ceiling and gates of the garage, but also the floor in order to minimize heat loss.

Warming can be done in different ways., but in fact, this is a rather problematic enterprise. Today, it will consider all the nuances in this regard, so that each reader can independently decide whether to get down to business, and if so, in what way.

Possible problems

If the garage is old or simply built initially without insulation, certain problems may arise with its further arrangement. Warming is a process that, according to the rules, is carried out during the construction itself, well, or immediately laid down in the plan. If you decided to insulate the garage only now, when this building has been used for several years, it will be difficult to do this. You may have to face the following difficulties:

  • First of all, this is the choice of material. There are quite a few interesting offers and high-quality technologies on the market today, but all of them are intended for timely work, and not for further decoration. It will not be easy to choose a material in accordance with the requirements of floor insulation at the stage of a building's full readiness for operation.
  • It is also important to note the point that floor insulation is a rather difficult task for a beginner if you decide to do it yourself. You will need to choose the material, prepare the surface, study the technology and conduct the process correctly from the very beginning.
  • The problem is that racks, cabinets, some equipment are already installed in the finished garage, tools and spare parts are stored. In the insulation of walls and ceilings, this is not a question, since insulation can be made from the outside. You only need to work with the floor from the inside, which means that you will have to clean it in a few days and resolve issues regarding the placement of everything available in the country garage for other rooms or buildings.
  • It is very important to note that when warming you raise the floor level, and how high this rise will be, depends on the material. But raising the floor is also a threshold that can interfere with the entry of the car and be not particularly convenient even for pedestrian entry. Of course, if it’s some 5-7 cm, there’s nothing wrong with that, but if the technology requires a lift of all 15-20 cm or more, this is already a serious problem.
  • In addition, the insulation of the garage floor is an expensive undertaking, if you use high-quality insulation material and further termination, and therefore immediately think about the budget, choose the materials, and only then get to work so that it does not happen that for some reason the process stops, and all the contents of the garage will just be on the street for the whole winter.
  • It is also worthwhile to understand that such work should occur in the warm season, when daylight hours and temperature allow you to finish everything quickly. In winter, working in cold weather is not very convenient, and mortars can lose a significant amount of their advantageous characteristics.

There are plenty of problems, and therefore it is worth considering whether to start work now or move it to the next spring, or maybe completely forget about this venture if you are not going to equip a workplace or a frequently used warehouse, repair cars and vehicles in winter, and so on.

Materials for work

The floor of the country garage is insulated with different materials, but the possibility of their use again depends on the time of the work, the stages in the construction and thermal insulation, budget, requirements.

Expanded clay, wood with a layer of polystyrene foam, wooden flooring on mineral wool, bulk floor, expanded polystyrene, polyurethane foam, expanded clay and other materials are suitable for work. You can also install a warm floor in the garage, but for this you will need to do even more.

Preparatory work

We carry out cleaning, ventilate the room and take out all the excess. We clean the floor of everything that is on it - paint, concrete chips, old wooden flooring and so on. And immediately we proceed to repair the surface, the simplest, by filling cracks and potholes.

At the end of the preparation, we boldly proceed to thermal insulation. Of course, these processes sometimes run counter to the technological requirements of high-quality insulation and the use of special materials, but we have repeatedly found a way out of a difficult situation, and today we will do it again.

Ideas for floor insulation in a garage room

Our main ideas are classic, but there are several exclusive ones that were put into practice and yielded excellent results.

Expanded clay insulation

The technology of thermal insulation expanded clay varies little from the place of dislocation of the material. Therefore, the floor in a new bathhouse, change house, summer house or garage is insulated with expanded clay the same way, taking into account only the features of the room itself.

After leveling the surface, the floor is covered with a moisture-insulating material, a dense film that is wound on the walls of the garage by about 20 cm and is well glued at all joints. Further, on top of the film there is an expanded clay embankment, which is compacted and leveled. Expanded clay in this case, it is better to choose different fractions to set a good density for the layer. The layer itself should be at least 20 cm. This is a serious rise in the floor, but it is necessary to find a way out of the situation.

After the expanded clay embankment and the leveling of the insulation material layer, an assembly metal mesh is installed on top of it, preferably in two layers. It must be on the frame, which will rest against the main floor of the garage, that is, into the concrete screed. We need a frame so that the floor screed poured in expanded clay meets all the requirements of strength and bearing capacity. The screed itself is poured with a layer of at least 4 cm and carefully leveled. The floor should dry about 7-10 days.

Foam insulation

We choose heaters depending on the requirements for thermal insulation and room characteristics, and therefore often foam or polystyrene foam is suitable for us - high-quality high-density insulators. You can use them in the garage.

After preparing the floor surface, the foam with a layer of at least 5 cm and the highest density, closer to PSB-S 50, is installed on the floor. Many also lay waterproofing under the boards of polystyrene or expanded polystyrene, which is a positive, but not fundamental factor. You can also use material brand PSB S-35, which withstands high loads and is designed specifically for floor insulation.

The material is laid on the adhesive composition, with which all seams are sealed. Further, a reinforcing mesh is spread over the surface of the material and a screed of cement-sand mortar is poured.

Fast and inexpensive option

It happens that there is simply no time for thorough work, and before the first cold weather it is necessary to at least minimize heat loss. Then some summer residents, like just motorists, use the following method - they cover the floor with wood or chipboards. Particleboard is poorly suited for this, as the material quickly deteriorates from moisture, but OSB boards work well.

It is important to understand that plates are not a single piece of material and can break and break at point or end loads. Therefore, the sheets must be fixed to the surface of the leveled floor, and the edges pressed down with a skirting board, sills, metal strips.

You can insulate the floor with boards. Of course, this will not have a serious effect, but at least the material will not be as cold as a concrete floor in winter. Boards are covered with mandatory fastening, as are boards, and are also compacted as much as possible.

You need to know that such insulation is only temporary, because the material is short-lived, deteriorates from moisture and overdrying. And if we talk about boards, the inconvenience also lies in the fact that the seams can quickly become clogged with garbage and dust.

Under-floor insulation

There is another interesting way that does not require serious expenses and skills, but most importantly for all those who are late with thermal insulation, and time. That is, a similar process can be completed in just a day!

Experts call this type of thermal insulation floor insulation under the flooring. It uses a combined version of thermal insulation - polystyrene foam and boards that fall on the logs. There is no need to spend money on expensive high-density insulation, because an average quality material will be enough, which is several times cheaper.

So, we cover it strictly according to the level of logs on the garage floor, for the production of which we select only dry and even wood, it is possible to inexpensive species. The whole tree is treated with antiseptics and moisture protection if you want this design to last a long time. Logs are stacked in small increments, approximately 40-60 cm, or depending on the width of the insulation. Logs are fixed to the floor and laid with insulating material. By the way, in this case, it can be not only polystyrene, but also mineral wool.

After laying the insulating material, the flooring of the board occurs, also necessarily dry. The board is laid evenly and fixed on the logs. The material must also be treated with protective equipment.

Other methods of insulation

There are other ways to insulate the garage floor, but they require more serious training and professionalism, and sometimes costs and special equipment. For example, insulation with polyurethane foam, or, in general, laying an electric heated floor in a garage. These are good ways that give excellent results, and therefore if any of our readers are interested in them, please contact the section Answers to questions!

Threshold and entry to the garage after insulation

Upon completion of work, we need to make a high-quality and convenient entrance to the garage, because the floor level often rises by 10 cm, 15 cm or more. By 10 cm increase, any technique will react normally, but if the floor level rises by 15-20 cm or more, it will be much more difficult to jump into the car. Therefore, even at the stage of installation of the insulation, consider forming a quality entry.

Remember, with any method of floor insulation, a threshold from the corner will be required on the threshold, so as not to cripple the entrance to the garage for the first few races. If the floor rises significantly, it is necessary to pour out an additional entrance, install metal guide strips and so on.

The large angle of entry is corrected by laying metal plates. Also, you can even the entrance with pieces of conveyor belt or even wide wooden boards. But if you do it for yourself and thoroughly, we recommend that you prepare the solution and make a lift from concrete with mandatory reinforcement.

Insulation of the floor in the garage in the country necessary to create the most comfortable environment inside. We really hope that you will be able to do everything efficiently and without involving third parties who will have to pay for the work.
