Dow StyrofoamTM WallmateTM Insulation styrofoam

  • Type X extruded polystyrene foam insulation for easy home installation.
  • Closed-cell structure minimizes water absorption and maintains high performance insulating quality.
  • Used to insulate interior basement walls or other areas of the home.
  • No messy adhesives required.
  • Quick and easy to install. Here are links to a series of informative installation videos on YouTube: 1 of 32 of 33 of 3.
  • When butted together, slotted "rabbet" edges on long edges form a slot between the Wallmate panels to accommodate a wood furring strip. When the furrring strips are attached to the basement walls with masonry screws, they hold the Wallmate in place. Drywall can then be nailed or screwed to the furring strips. 
  • R value = 7.5 at 75° F.
