Ventilated concrete floors flooring material reinforced concrete floor slab casting protection thermal insulation. The recommended minimum area of ventilation required for under a suspended timber floor is 1500mm 2 for every metre of perimeter of the structure. Warm heat distributed with forced hot air systems is uneven.

In simple terms an air brick is simply a brick with holes in it. This usually happens when concrete slabs and the other materials that sweat reach dew point temperature. Cross flow ventilation was traditionally achieved by placing sleeper walls see figure 2 at intervals throughout the sub floor. Paroc grs 20 supporting structure.
