Expanded Polystyrene (EPS)
Lightweight, moisture-resistant and dimensionally stable. EPS is the workhorse of the construction industry — boards, shapes and custom profiles cut to your specification.
About the product
Versatile, cost-effective insulation for the built environment
Expanded polystyrene is one of the most widely specified insulation materials in construction. Its combination of low thermal conductivity, structural versatility, moisture resistance and low weight make it suitable across walls, roofs, floors, under-slab installations and cold room panels.
We supply EPS boards and custom-profiled shapes in densities from 15 kg/m³ to 40+ kg/m³. Higher density grades offer improved compressive strength for under-slab, load-bearing and structural applications.
Key performance data
Applications
Where EPS is specified
Walls, Roofs & Floors
Board insulation for residential and commercial construction meeting SANS 10400-XA and Green Star energy compliance requirements.
Under-Slab & Perimeter
High-density EPS under concrete slabs and at foundation perimeters. Dimensionally stable under load, unaffected by ground moisture.
Cold Room Panels
EPS cores for composite cold room and controlled-environment panels. Custom cut to panel dimensions with consistent density throughout.
