When sharp variations in temperature occur, condensate appears both on and under the roofing material. Condensate is water that originates from the air. It exerts destructive effect on structural units. To collect and divert water into gutters water insulation material is used.
Heat insulation is necessary to protect a building from ambient temperature fluctuations. It keeps the interior warm in winter and cool in summer. Correctly installed heat insulation allows to save energy expenditures. As a heat insulation material mineral wool is frequently used.
VAPOUR BARRIER INSULATION
Vapour barrier insulation protects structural units and heat insulation from penetration of vapour from the interior.
