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.

Why Homeowners Choose SANBOARD:

Cooler, energy-smart homes


SANBOARD reduces heat transfer through concrete roofs, lowering indoor temperatures and cutting the need for air conditioning during hot months.

Built for South African climates


Highly moisture-resistant and durable, SANBOARD withstands harsh weather conditions, including intense sun and heavy rains.

Long-term roof protection and value


In addition to energy savings, SANBOARD protects your roof structure and waterproofing layer, improving your home’s overall energy rating and market appeal.
