FOAMULAR® Insul-Drain-2.25x48x96

Owens Corning® FOAMULAR® & FOAMULAR® NGX® INSUL-DRAIN® boards are extruded polystyrene (XPS) products that incorporate the features of insulation, drainage, and protection board in a single product. It’s easy to install, without the need for special tools or equipment, and the product’s compressive strength and long-term moisture-resistance properties mean years of reliable performance on below-grade foundation walls even under extremely harsh conditions. Precision-cut channels drain water from vertical foundation walls while completing the total insulation envelope. 

FOAMULAR® NGX® INSUL-DRAIN® contains the additional benefit of being manufactured with a blowing agent formulation that delivers a 90% reduction to Global Warming
