INSUL-DRAIN® board is a FOAMULAR® extruded polystyrene (XPS) product that incorporates 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
Features
• Durable filtration fabric prevents soil from clogging channels
• 48″ x 96″ size covers more square footage faster and minimizes joints between boards
• Acts as protection course for waterproofing membrane
• Tongue & groove edges provide proper board alignment and help seal joints
• Top-edge horizontal channel permits unobstructed water flow between vertical courses of boards
• Excellent long-term stable insulating performance of up to R-10.61
• Exceptional moisture resistance, long-term durability
• Lightweight, durable rigid foam panels are easy to handle and install
• Easy to saw, cut, or score
- R means the resistance to heat flow; the higher the R-value, the greater the insulating power.
