MORE ABOUT EXPOL-X Edging

Specifiers looking for a product that offers excellent performance for a range of uses in diverse climate conditions turn to EXPOL-X.  Often used in applications that are subject to pressure and moisture, EXPOL-X is a high performing extruded polystyrene insulation product.

EXPOL-X polystyrene insulation sheets sit vertically against the outside face of the concrete slab or foundation wall, creating a thermal barrier in an area that is often responsible for significant heat loss. Once boards are fixed in place, a layer of plaster over the top will finish the edge to create a clean look.
