abeproof thermo-shield, a new heat-shielding and waterproofing product from a.b.e. Construction Chemicals, was used recently to waterproof a large roof area of the Sunbel building in Voortrekker Road, Bellville, Cape Town. abeproof thermo-shield is a water-based waterproofing membrane which incorporates advanced insulation technology. It contains fine spherical particles that minimise the surface temperature on roofs and walls by re-emitting most of the radiant heat energy away from the building before it can reach the interior. As a result, internal temperatures are kept low and the energy costs required to cool the building are reduced.
