What Is Insulation?

Insulation is a material designed to slow down the transfer of heat and sound within a building. In South Africa’s varied climate, insulation helps reduce heat gain in summer, limit heat loss in winter, and stabilise indoor temperatures throughout the year.

When selected and installed correctly, insulation improves comfort, lowers energy usage and supports long-term building performance.
