How to insulate the foundations foam - practical advice

Before you insulate foam foundation at home, you need to find out what it's done.The supporting structure of any buildings, particularly private houses, amenable to low temperatures, which, in turn, become a cause of swelling soil and foundation integrity damage.

Insulation helps to keep not only about 20 percent of the heat energy inside the underground space, but also prevents the disruption of the structure due to ground heave in the winter season.

Important!Insulation should be placed around the perimeter of the structure to its integrity was the key to the longevity of the house.

choice of material as a basis for quality work

From what material is selected for the type of work depends on the final quality of the construction process.The foam is considered to be the ideal choice for underground operations, because it perfectly resists moisture and can not be directly exposed to solar rays deplete.

There are several basic types of material that can be used for thermal insulation of the foundation design at home:

• foam plates having a size 100h100h5 cm;
• Pressed foam, whose thickness is less than 2 cm;
• Penoplex having different colors.

The use of each type of material actually required at work, but more often it is used penoplex.The thickness of the insulation is 20 mm, which has a positive impact on the process of assembling and finishing.

Important!A layer of insulation should be holistic, to exclude the possibility of heat loss.

order of installation work, in which the result will be as effective as possible

Before attempting to install a heater in the house foundation design should ensure it dry.If the surface of the supporting structure is wet, after her skin the moisture can not evaporate, leading to the formation of fungus and zaprevaniyu.Mounted insulation boards with screws or nails with large washers.After mounting consumables all hats must be treated with bitumen or similar material to prevent moisture ingress through possible openings.

Important!Do not leave a large gap between the elements of the material, it will lead to bad tightness of the whole structure.

To avoid poor integrity of insulation layer, all the seams between the elements of the material must be treated with foam.Only after drying foam can fill foundation ditch.Foam for the foundation should not be below ground level.This will lead to a constant moisture at the interface of the material and the foundation.As a rule, the insulation should extend beyond the ground level is not less than 150 millimeters.

Ideally, the material must be placed in such a way that it covers and the ground floor, which is subject to any material finish.It is necessary to remember the fact that all elements of the insulation should be free of cracks and holes that have to plug the supporting material.
