Proven thermal comfort, lower energy costs, and nationwide delivery you can rely on
Energy-Smart Walls, Engineered for South Africa – Moisture-Resistant, Code-Compliant
Built for Thermal Comfort, Energy Savings, and SANS 10400-XA Compliance
SANBOARD XPS cavity wall insulation is a rigid, high-density extruded polystyrene (XPS) board installed between the inner and outer layers of cavity wall construction.
It’s purpose-built to meet the SANS 10400-XA energy efficiency standards — including the thermal insulation requirements for double-brick or cavity wall assemblies.
Why Homeowners Choose SANBOARD:
✔ Comfortable, energy-smart living
Installing SANBOARD inside your cavity walls reduces heat transfer through the building envelope. The result? A more consistent indoor temperature, lower energy bills, and year-round thermal comfort.
