Loss of heat through floors on concrete surface beds is experienced as a cold underfoot condition, particularly during winter when the supporting soils cool down due to hygroscopic action of water. In order for rooms to be heated or cooled energy efficiently, the floors need to be insulated from the surrounding soil bed to prevent soilbed from being heated.

IsoBoard Insulation installed over purlin under roof sheet. — In South Africa, the bulk of retail and industrial buildings are steel-sheet clad frames, where 70% of the heat gain is through the roof. IsoBoard over purlin insulation is the most cost effective method of achieving thermal efficiency in these buildings.

Isoboard cavity wall insulation will prevent heat transfer and build-up to the inner leaf of sun exposed walls. Moisture within the cavity is prevented from condensing onto and penetrating through the inner leaf when IsoBoard is installed. The insulation restricts heating ingress to temperature controlled and passive cooled environments.
