Thermofill is a pumped foam-concrete ground cover used to seal damp or wet ground in the sub-floor space under buildings. The purpose of its application is to reduce moisture vapour rising up through the building, thus reducing indoor relative humidity.
Thermofill has been appraised for use as a ground cover vapour barrier for use in the sub-floor space of buildings to reduce the moisture evaporating from the ground under the floor within the following scope:
- as a vapour barrier for use in existing building; and,
- as an alternative to the vapour barrier specified in NZS 3604, Paragraph 6.14.3.
The installation of Thermofill must be carried out only by personnel authorised by Canterbury Foam Concrete Ltd.
