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

JADE HOMES 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.
