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.

Built for South African conditions

 

SANBOARD is moisture-resistant, structurally strong, and immune to rot or mold. It performs reliably in both inland and coastal environments where weather and moisture are factors.

Long-term value for your home


SANBOARD improves wall insulation, reduces thermal bridging, and enhances your home's energy rating — adding real value in energy-aware property markets.
