Why insulate the floors of the first floor?
The first floors of private houses separate warm rooms from the ground or basement.
In winter, soils freeze, and when installing a slab foundation, if it is not thermally insulated, heat transfer occurs through the floor into the ground.
If the house is on a foundation with a ventilated underground, the temperature under the first floor is identical to that currently established outside. In this case, the floors, like the house’s walls, must be protected from cold air.
Heat is transferred through the floor to the unheated basement when installing floors above a cold underground. When a person goes to the basement, it is always much harder than in the house. The soil constantly removes heat from the air space of the buried structure. To prevent this, you need to insulate the base, the basement walls, and the ceiling of the first floor of a private house.
It is necessary to insulate the floor so the premises are always comfortable. Thermal insulation of the ground floor reduces home heating costs and forms a reliable barrier against heat loss through the feet.

Types of floors for the first floor
In private houses, the feet of the first floor are divided into:
- Floors with joists
- Floors on the ground
- Floors above a recessed room (basement, garage, technical room)
- Features of application
- Floors along joists on the first floors are installed when constructing private houses on shallow and deep strip foundations, columnar and pile foundations. Under the ventilated underground, a zone of atmospheric air is formed, with the same temperature as the street air. Heat loss through the floor can be reduced using a structure with thermal insulation made from extruded polystyrene foam PENOPLEX FOUNDATION.
Floors on the ground are installed during the construction of houses on shallow and deep strip foundations and slab foundations, including insulated slab foundations.
Ground floor structures include highly effective thermal insulation made of extruded polystyrene foam PENOPLEX FOUNDATION, which protects the floor structure from heat transfer from the heated room to the ground.
A separate type of floor: above unheated recessed structures. In this case, PENOPLEX FOUNDATION protects the floor structure from the cold air of the underground.
Thermal insulation is an important part of a multi-layer floor construction system. Insulation in floors takes increased loads and must maintain its properties throughout the entire service life of the structure.

Why PENOPLEX FOUNDATION
If the floors along the joists are insulated using mineral wool, which is mounted between the posts, then in the future, this structure will not protect the house from the cold. The strength of cotton insulation is low; over time, it begins to settle, and large gaps form through which the cold penetrates the house. Gradually getting wet, cotton wool eventually becomes not a heat insulator but a conductor of cold and will have to be replaced with a durable and moisture-resistant material. It is necessary to use durable thermal insulation on floors along joists, which forms a continuous thermal insulation contour by laying not between the posts but on top of them.
In-ground floors, it is very important to use durable thermal insulation. Over time, cake thickness decreases, leading to a sharp deterioration in the thermal insulation properties of the structure. Repairing the floor, in this case, will require replacement and a topcoat, which will be much more expensive than immediately applying reliable and durable thermal insulation.
