We insulate the country house: the choice of material and the preparation of the facade.

Two materials are usually used in houses insulation: polystyrene foam; Mineral wool.

Their indicators in terms of thermal conductivity are close, but vapor permeability differs quite seriously. It is this coefficient that affects the choice of material for thermal insulation of certain walls. Also, cotton and polystyrene foams have different indicators in fire resistance, reaction to chemicals and elasticity.
