The service life of the building primarily depends on the foundation, therefore it is important to adhere to certain technologies during construction.
Insulation of the columnar foundation is an important factor.
The columnar foundation has a number of advantages in comparison with others: it is easy to create, the price is many times less than a monolith, it is easy to repair and lasts up to 100 years ..
. It is necessary to insulate it for the same purpose as a monolith - to minimize heat loss.
By insulating the foundation, you thereby protect communications from freezing and possible mechanical damage.
Having performed the insulation correctly, the heat loss in the house will be reduced by 20-25%.
As an insulating material, you can use:
! Important. Rodents can start in any insulation; during installation, take care to protect it from external damage.
Advantages of outside foundation insulation:
The disadvantages of using this type of insulation, including for a shallow columnar foundation, have not been identified.
! Important. The use of this type of insulation has serious drawbacks, so in practice it is rare.
Advantages of foundation insulation from the inside:
Disadvantages of internal insulation:
If you decide to insulate the foundation without resorting to the help of masters, the first thing to start with is choice of material. As mentioned above, penoplex would be an ideal option. Penoplex is foam polystyrene plates, the thickness of which ranges from 2 cm to 10 cm.
To insulate the foundation or basement, a thickness of 10 cm is needed (you can use a double layer of a 5 cm plate). To protect against moisture, it is necessary to install a blind area around the perimeter of the house.
In order to protect the air cushion between the floor of the house and the ground from the cold during the frost period, you first need to create a wooden frame between the posts. The next step is to attach the foam panels to the frame with dowels and screws.
Seams between the boards must be properly treated with polyurethane foam.
Next, you need to protect the insulation from possible mechanical damage and exposure to ultraviolet radiation. Siding or plinth panels are perfect for this.
When creating a blind area, you need to remember that its height above the ground should be 10-15 centimeters, regardless of the material from which it is made (it can be concrete or paving slabs). If the base is not provided between the posts, only the grillage needs to be insulated. If you use mineral wool to insulate the floor of the first floor, according to the technology, a layer of 10-20 centimeters must be laid between the floor beams and covered with a waterproofing film.
After that, a floorboard with a thickness of at least 40 mm can be laid on top.
