Outstanding Insulation Helping You Meet SANS 10400-XA Thermal +3.5 R-Value Requirements

Engineered Thermal Protection For Your Concrete Roof Slab – R-Value Compliant, Homeowner Approved
Designed for Cooler Roofs, Energy Savings, and SANS 10400-XA Compliance
SANBOARD concrete roof insulation boards are rigid, high-density extruded polystyrene (XPS) panels installed on top of your home’s concrete roof slab.
They create a crucial thermal barrier that blocks heat from the sun, reducing heat transfer into your home and protecting the waterproofing layer below.
Typically covered with a woven geotextile and a stone layer, or designed to receive a concrete topping, SANBOARD delivers superior insulation and long-lasting roof protection.
