Rigid Foam Board Insulation XPS R-5 2' x 8' x 1"

Western Works XPS Rigid Foam Board Insulation provides continuous thermal insulation with minimal thickness.
The closed-cell extruded polystyrene structure delivers superior moisture resistance and compressive strength, making it ideal for foundation walls, slab edges, and exterior wall sheathing.
Features: Closed-cell XPS structure resists moisture absorption. High compressive strength (25 psi) for below-grade applications. Long-term stable R-value — won't degrade over time.
Lightweight and easy to cut with a utility knife. Specifications: R-Value: R-5 per inch of thickness. Dimensions: 2' x 8' x 1". Compressive strength: 25 psi.
Water absorption: <0.7% by volume. Coverage: 16 sq ft per board.
Applications: Foundation walls, slab perimeters, exterior wall sheathing, crawl space walls, cathedral ceilings, under slab insulation.
