The presence of warm floors is a high comfort and a healthy life for all tenants of the house. In addition, the cold coming from below leads to heat loss, which affects the family budget. It's no wonder that the question of how to make the insulated floor in a private house, now worries many owners of private buildings. Here we give a simple example of how to fix this problem using easily available building materials.
Than to warm the floor in the house?
- Plates made of expanded polystyrene.
- Thermal insulation of the floor with polyurethane foam.
- Mineral wool.
- Granules of expanded clay.
This material is of different design. More improved plates have milled edges, which allows them to overlap, and ordinary plates come with flat edges. It is possible to mount two layers of a thin material or use a thick polystyrene immediately in one layer. Extruded material has better characteristics and can withstand considerable loads. Such a strong foam polystyrene can be laid directly on the floor of expanded clay, not engaged in the arrangement of screeds of concrete.
It is better to use polyurethane foam plates with a protective coating in the form of a layer of foil or fiberglass, which will help reduce the vapor permeability of the material.
This is a fairly high-quality and affordable insulation, but it requires a firm and even foundation. There are quite dense and practical plates that have a hardness of 150 kg / m. It is this material that many owners use to solve such a serious issue as warming the floor in a private house.
Previously, it was the most popular building material, but it is inferior in performance to mineral wool and expanded polystyrene, and is also prone to fungus and mold . Usually claydite is poured under the floor with a thick layer from 25 cm to 40 cm.
How to insulate the floor from the inside in a private house?
- To work on insulation we will need thermal insulation panels made of mineral fibers.
- Also, for the arrangement of the floor, wooden lugs from the timber will be required.
- First, we level the rough floor and remove the debris, and then we put a vapor barrier film on top.
- On the perimeter of the room we lay the edge strip from the heater.
- Then we fix wooden lags to the floor.
- Between the lag we lay insulating plates. If there is no heated room from below, then their thickness should not be less than 50 mm.
- The distance between the lags should be designed so that the plates of mineral wool tightly between them.
- From above put the distribution boards (chipboard or fiberboard).
- In places of joints we fix the board or plates to the logs by a mechanical method (screws).
- The next layer is the substrate (foam, tulle, parcol).
- The last coating is a finishing floor made of parquet, linoleum or other material.
How is it better to insulate the floor in a private house with a basement?
Ground freezing is the source of significant heat losses in winter. It is desirable to conduct insulation work on the outside of the building, preventing the contact of masonry with cold soil. For these jobs is suitable expanded polystyrene, which has a good indicator of thermal conductivity. The ideal option is the insulation of the entire basement. The lower part is then covered with soil, and the upper part is covered with a decorative coating.
Warming of the dwelling on the lower floor side
If you do not want to carry out repairs in a dwelling, you can draw them from below, attaching a heat insulator to the ceiling of the basement. Mounted plank flooring, laid mineral wool or other material with similar characteristics, and then this box is closed with plasterboard slabs or boards. This method is also quite suitable for how you can properly insulate the floor in a private house.
