Heat escapes through the foundation, to warm it!

Methods of insulation of the foundation 

expanded clay aggregate

Loose insulation used for thermal insulation of the basement at home for a long time. In the old days used mulch, hay, straw, and every kind of slag. However, concrete block - more quality insulation. He has a low thermal conductivity and low price.
In comparison with other heaters it is seriously losing quality. Its main advantage - low cost.

Important: to qualitatively insulate the concrete block house need to fill and seal the thick, otherwise it draws the moisture from the ground and loses its effectiveness. For example, in most of Russia for warming homes layer need meter expanded clay.

In general, it is important to understand that the foundation of expanded clay insulation - it is too time-consuming work.

polystyrene

The easiest and most convenient method of insulation of the foundation, especially when using expanded polystyrene sheet. Its advantages are:

• resistance to moisture;
• strength;
• easy installation;
• not afraid of rodents;
• easily plastered;
• It can be mounted on their own;
• affordable price.

Recommended film thickness - 5 - 10 cm.

Polyurethane foam

In contrast to the previous type of insulation, polyurethane foam is sprayed directly onto the foundation walls themselves. This is - the most important advantage of polyurethane foam, because the whole procedure does not last long and does not require glue for fixing. Another advantage - in the absence of the joints, through which cold air to penetrate inside.

For thermal insulation of the foundation will suffice 5 cm polyurethane foam layer. Polyurethane foam is also - a good waterproofing of the foundation, because he is not afraid of moisture.

It's important to know: make such insulation itself is difficult, because Special equipment is required for spraying. However, it is possible to rent and spend warming themselves.

Output:

The cheapest, but time-consuming, is expanded clay insulation.
The most expensive, but fast - polyurethane foam.
Polystyrene - an intermediate option.
