Warming of the floor is a very important task inproviding heat and coziness in the room. This issue is especially important when the apartment is located on the ground floor, when the basement is under it. Warming of the floor covering from the basement is actual in a private cottage. 
Variants of floor insulation over the basement.
What is the purpose of warming?
The process of heat exchange in a private house or apartmentvery often depends on the construction of the floors, because their surface is the place of the greatest heat loss. This is especially true when the floor is made of concrete. Concrete - a durable material with good performance, so it is often used for the manufacture of flooring. 
The scheme of insulation of the ceiling of the basement with mineral wool. Despite its good characteristics, concrete is also a very cold material. If the concrete cover is used in a dwelling, it will be necessary to conduct a sufficiently good thermal insulation, otherwise any heating will be ineffective. The presence of a cold surface will create uncomfortable conditions of stay in the room, which will lead to large expenses for heating. In addition, if there is no thermal insulation of the surface, under which the basement is located, this will cause the formation of dampness and mold on the surface of the walls. To avoid this, it is necessary to arrange a heat-insulating construction qualitatively. At the same time, warming the floor is not a complicated procedure. It can be performed by any owner of the premises on his own, possessing the necessary material and tools. Back to contents</a>
Material selection
Currently in the construction market there isseveral types of insulation material. This material is available in loose, liquid, roll and block form. In this case, any of them can be used to insulate the room, under which there is a basement. As a block material, various plates and mats are used. This type of insulation has a low coefficient of thermal conductivity and low weight. Block heaters are very good to apply from the basement. They can be used together with the roll material, which will lead to an increase in the overall thermal insulation. Block type material is made of mineral wool, foam, basalt fibers or other materials having a composite structure. 
The scheme of insulation of the floor with expanded clay. The bulk materials include the following:
- expanded clay;
- sawdust;
- polystyrene crumb;
- slag waste.
Their use will completely fillFree space between the floor surface and its base. You can apply bulk materials directly on the open ground or in any private structure, at the bottom of which there is a cold basement. As a roll insulation, mineral wool, any composite having a cork base or any multilayer foil-based insulation can be used. The thickness of such materials can be different, but mostly has a size of 8-10 cm. As a liquid insulation, various solutions based on cement are used, which include foam plastic chips, wood chips, expanded clay or other similar materials. At present, foamed polymer floors based on foam is widely used. To install it, you need to use specialized equipment. It's quite difficult to do it yourself. Back to contents</a>
How to perform insulation?
To properly perform the required work,it is necessary first of all to dismantle the old coating. You need to do this carefully, then you can use it again. To insulate the floor, at the bottom of which there is a basement, it is necessary to take into account the load that will occur on all layers of the structure. To minimize them, all the material must be laid in a certain sequence. To perform all the installation work, you need the following tool: 
Tools for floor insulation.
- Screwdriver;
- Screwdriver Set;
- a hammer;
- knife;
- building level.
The first step is to dismantleold cover. After the old coating is removed, it is necessary to inspect the log. Damaged lags will need to be replaced. After that, they must be treated with an antifungal antiseptic, which will help in the future to prevent mold on their surface. How the antiseptic will dry out, you can lay the waterproofing. After that, the necessary insulation is laid. In the event that the height of the log is quite high, you can lay 2 layers of material. Here you can perform a combination of insulation on its different layers (bulk and roll). Then you need to put a vapor barrier film, and on it a plywood board. On top of the plywood can be laid thin roll material (substrate), the thickness of which is 1-4 mm. And only then the final surface is finally laid out. At the stage of building a house it is better to make preliminary warming. It is carried out in the same order. This will avoid further problems during operation. Back to contents</a>
Carrying out works in the basement with your own hands
Scheme of insulation of the floor in the room above the basement. If there is a possibility, it is possible to perform work on the insulation and from the basement. It is performed on the ceiling of the basement. For this, polystyrene foam is the best choice, since it is not afraid of high humidity. Polyfoam is glued to the surface of the ceiling with special glue. After the glue dries, the gaps between the plates must be filled with a mounting foam. When the foam solidifies, its excess should be removed with a knife. You can use other similar material. But polystyrene is one of the most inexpensive. Moreover, in case of damage, it can easily be replaced. To ensure that the heater has performed its functions qualitatively, the seams between the layers of vapor barrier and waterproofing film need to be glued with adhesive tape. This will ensure their integrity. In order to prevent condensation in the future, do not cover the ventilation openings. The presence of ventilation will help also to keep the floor covering in good condition. In the event that the apartment is located on the 1st floor and there is a basement under it, do not wait a long time to postpone the installation work on the insulation. If you tighten them, the room will be cold and damp. And in the future this will lead to the formation of fungi and mold not only on the surface of the floor, but also on the walls.
