With limited space around properties, some people are starting to extend their homes down rather than out. Whether it is a new basement construction, or an existing uninsulated space below the ground floor that is a source of unnecessary heat loss, a range of Celotex products can be used to increase the thermal efficiency of the construction.

General purpose boards can be used on the wall and floor, as long as they are positioned to the internal side of the chosen waterproofing/tanking solution. Lining the walls with insulated plasterboards can then provide a finish ready for decoration, and help get the U-value down to the target.
