FOAMULAR® PINK-DRAIN® Extruded Polystyrene Insulation Board

ASTM C578 Type IV, 30 psi, minimum X pcf density

PINK-DRAIN® board is a FOAMULAR® extruded polystyrene (XPS) product that incorporates the features of insulation, drainage, and protection board in a single, closed cell product for the exterior foundation wall. 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. Like all FOAMULAR® XPS products, FOAMULAR® PFD is highly resistant to moisture and permits the product to retain its high R-value year after year even after exposure to water, soil, condensation, and freeze/thaw cycling. Some of the main characteristics of FOAMULAR® PINK-DRAIN® XPS are:
  • Precision-cut channels drain water from vertical foundation walls while providing a continuous envelope of insulation.
  • Channel design prevents soil from clogging channels assuring long-term performance.
  • 24” x 96” size covers more square footage faster and minimizes joints between boards.
  • Acts as protection course for waterproofing membrane.
  • Shiplap edges assure continuous insulation coverage.
  • High R-value, exceptional moisture resistance and high compressive strength.
  • Minimum compression strength of 30 psi.
  • Available in thickness for R-10.
  • UL Classified foam core meets ASTM C578 Type IV specifications.
