Insulate floors, directions and advice

Insulate floors in a home environment it is a complex job but one that has the counterpart of increasing the home comfort and energy efficiency of the building. Thereinsulationit is the most efficient way to eliminate condensation, rising damp and make the home more livable and healthy. A well-insulated house is also more efficient by significantly reducing the costs of winter heating and summer cooling.

Insulate an existing floorit is even more difficult: in this context the insulating layer must be internal so there are two ways to go:
- lay an insulating layer on the existing floor and then re-floor with the dry method.
- Remove the existing floor, add the insulation and re-floor.

In the first case it will be necessary to deal with skirting boards and door and window sizes that will have to be changed due to the greater thickness added to the existing floor, moreover, it is an operation that is almost always not feasible. To improve the degree of insulation of an existing floor, it is possible to use carpeting. In the second case it will be necessary to deal with a longer procedure.

The materials used forinsulate a floorthey must be resistant to pressure and foot traffic. Among the most widely used insulating materials for floor insulation we mention rock wool, glass wool felt, vermiculite and a long series of synthetic products laid in the form of rigid sheets, carpets or self-hardening foams. The insulating layer can have different thicknesses depending on the case.

For a flooring to be built from scratch, it can be positioned directly above the slab, above the pipes of any systems, then drown everything in the screed for the flooring.

When is it necessary to insulate the floor?

Thereinsulation of the flooringit is necessary for those rooms that arise on unheated rooms such as garages, cellars, taverns or for rooms built directly on the ground so as to eliminate the problem of surface condensation. Insulate the floor it is convenient in the case of the attic located on the top floor of a house, above the living area and in contact with the uninhabited attic. Also in this case, significant improvements in energy efficiency can be achieved. In absence ofinsulated floorsenergy waste can reach 20%.

The floors on the ground

If thefloorit rests directly on the ground, it will be necessary to place a thermal insulator on the slab over which the screed will be created which, to protect the chosen insulation, must preferably be reinforced with an electro-welded mesh. In the case of swampy or particularly humid areas, a waterproof layer can be placed under the insulating layer. On the contrary, thefloor insulation overlooking the arcades or open spaces, is made with a "coat" system, this implies the placement of the insulation at the lower face of the slab.
