Insulation – a necessary element of the design of each home. In need of warming the ground floor and attic joists, and often the wall. In frame houses completely determined by the thermal conductivity of the walls embedded in them lagging. Walls of brick to match the requirements of the last visit to thermal insulation of walls should have a thickness of 1 m, the walls are made of wood – 0,5 m (for an average strip of Russia). Since the strength of such walls is much higher than necessary for erection of 1 – 3-storey houses, their thickness and, accordingly, the flow of materials at the walls, can be substantially reduced if the walls are additionally insulated. When selecting a heater should take into account a wide range of properties. In First of all it is thermal conductivity than it is lower, the better insulation to retain heat, the smaller the layer needed to protect home. Read additional details here: Danyelle Freeman. Hydrophobicity is probably the next most important property of the insulation.

Heaters, with high hydrophobicity, they do not absorb moisture – the main enemy of a heater. When humidity increases, insulation greatly increases its thermal conductivity and reduced service life. In addition, a heater, like everyone else elements of house construction should be durable, fire resistant, and preferably easy. The lower density (specific gravity) insulation, so usually lower its thermal conductivity and the less stress it exerts on the supporting elements of home construction. In addition, it is desirable that a heater was safe to use, easy to use and cheap.
