Insulate Right from the Ground Up – Comfort, Efficiency & SANS 10400-XA Compliance
Engineered Warmth Beneath Your Feet – R-Value Compliant, Homeowner Approved
Engineered for Warm Floors, Lower Bills, and Code Compliance
Sanboard surface bed insulation is a rigid, high-density extruded polystyrene (XPS) board installed beneath your home’s concrete floor slab. It’s specifically designed to meet the SANS 10400-XA energy efficiency requirements — including the minimum R-value of 1.0 for homes using underfloor heating systems.
✅ Why Homeowners Choose SANBOARD:
✔ Comfortable, energy-smart living
Installing SANBOARD under your slab creates a thermal barrier that prevents heat loss into the ground. The result? Warmer floors in winter, lower heating bills, and better thermal comfort all year round.
✔ Built for South African conditions
SANBOARD is water-resistant, high-compressive strength, and resistant to rot or decay. It performs exceptionally well in slab-on-ground construction, even in moisture-prone environments.
✔ Long-term value for your home
Sanboard enhances your home's energy performance, reduces heating and cooling loads, and contributes to a higher resale value in energy-conscious markets.
