Storey ceiling insulation

Unfinished attics are the biggest energy guzzlers. Heat always rises and, in the absence of insulation, escapes through the roof into the atmosphere.

By insulating the upper floor, heated living spaces can be separated from the cold zones of a house. The excellent insulation value of WILLFLEX® 022 can save up to 30 percent on heating costs. In older buildings, insulation is mandatory. Top floor ceilings above heated rooms that cannot be walked on but are accessible must be insulated so that the heat transfer coefficient (U-value) of the floor-ceiling does not exceed 0.24 W/m²K.
