DOW 2" x 4' x 8' Rigid Foam Insulation Board (Grey)
Maximize your energy efficiency with the industry standard in moisture resistance and thermal performance. This 2-inch thick Extruded Polystyrene (XPS) board is engineered to provide a continuous insulation layer that eliminates thermal bridging, keeping interiors warmer in the winter and cooler in the summer.
Key Features
Superior R-Value: Delivers a consistent R-10 insulation rating, significantly reducing energy costs.
Moisture Resistance: Unlike fiberglass or open-cell foam, this closed-cell XPS resists water absorption, preventing mold growth and maintaining its R-value even in wet soil conditions.
High Compressive Strength: Durable enough for use in under-slab applications, foundation walls, and heavy-duty roofing projects.
Easy Installation: Lightweight and easy to score, cut, and snap for a precise fit around outlets, piping, and irregular corners.
