50mm XPS Foam Sheet

XPS (Extruded Polystyrene) Foam sheet has become the material of choice for underslab insulation due to its high compressive strength and superior thermal resistance. Thanks to advances in manufacturing techniques, XPS foam (or underslab foam) is also impervious to water, further increasing its thermal performance XPS foam has a number of applications including; concrete slab and foundation insulation, perimeter insulation, isolation joints etc.
