Work on insulation of the house should be carried out comprehensively: insulation of foundations, insulation of the outer walls, insulation of the floors of the first floor, warming of the ceilings, roof insulation. Otherwise, it is impossible to get a fairly effective heat conservation system. Insulation begins with foundations. The foundations should be insulated to the entire height, I turn on the so -called base, which protrudes above the ground. When choosing a heater, it is necessary to decide what the foundations are made of. It can be like a monolithic reinforced concrete, brick, prefabricated reinforced concrete, laughter stone. Both mineral wool -based mineral wool -based minerals and polystyrene foams, and expanded clay, are suitable for all these types. When laying each of these insulations, there are its own characteristics, but unites their common qualities, they are not hygroscopic (do not accumulate moisture), expanded clay and mineral insulation is not fuel. When choosing as a heater for the foundations of expanded clay, special formwork is performed from the waste from the boards around the perimeter of the foundation. Ceramzite is falling asleep into the formwork. As noted above, insulation is carried out to the entire height of the foundation. If the choice of insulation has stopped on foam slabs, then they are glued on a special mastic directly to the waterproofing of the foundation. In this case, the joints between the foam slabs are filled with mounting foam. After the mastic and foam of the plate dried, you can plastered, with cement -based solutions. When the mineral slabs or roll materials are used as a heater, a special crate is attached to the foundation, into which the insulation is inserted with subsequent casing either siding, or plastering with cement solutions in special mesh. All types of insulation should be selected based on heat engineering calculations, but in the absence of calculations, it is necessary that the thickness of the insulation is at least 100 millimeters. All of the above heaters are approximately equivalent in their heat engineering properties. But the foam has one drawback, rodents love it very much. If you have to lay polystyrene slabs, then it is necessary to treat the plates with a special composition, or carefully plastered the insulation. Expanded clay and roller heaters are ideal for foundations made of bottle stone, or having not even surfaces.
