Foundation Perimeter Insulation
The effect of this application is very simular to under floor slab insulation, however, perimeter insulation can be a retrofit installation. IsoBoard is inserted against the foundataions of the building on the outside from the surface to the depth of the foundataion or 600mm, whichever is greater. By insulating your foundataions to this depth, your building is not subjected to heat transfer through the floor from adjacent soil temperatures, which may range from 40 °C to frozen. The IsoBoard insulation maintains your floor slab at an even moderate temperature, assisting in controlling the temperature of the building.
