100mm knauf insulation johannesburg

The 100mm Knauf is one of the most popular insulation products in South Africa. It’s SANS compliant with an R-value of 2.50 and a 12kg density.

A typical un-insulated home gains or loses up to 35% of its energy through the ceiling.

The net result is a home that is uncomfortably hot in summer and cold in winter.
