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.
Insulation by Application
Different parts of a building require different insulation solutions. Browse insulation products by application below.
- Roof Insulation – Used to reduce heat entering through roof structures and roof cavities.
- Ceiling Insulation – One of the most effective ways to improve indoor temperature.
- Wall Insulation – Suitable for cavity walls, drywall systems and sound-sensitive areas.
- Floor Insulation – Helps reduce heat loss and noise transfer between floors.
- Soundproofing Insulation – Reduce airborne and impact noise.
- Fire-Rated Insulation – Improve fire resistance and slow heat spread in high-risk areas.
Insulation by Material
Insulation materials differ in performance, handling characteristics and suitability for specific applications.
- Mineral wool – Dense, non-combustible insulation for fire-rated and acoustic use.
- Glasswool – Lightweight bulk insulation commonly used in ceilings and roofs.
- Stone wool – High-density insulation for fire-rated and acoustic applications.
