How do I install XPS on my basement wall?

• You can glue or fasten the board to the concrete wall. When applying the glue, place a minimum of 5 large sections of glue in the 4 corners and one in the center. Install the board to the wall and apply pressure until the glue holds tight.You can find compatible adhesives in our TB11. Kingspan recommends Loctite Power Grab Adhesive.
• You can fasten the board to the wall with 5 Plasti-Grip PMF Anchors from TRUFAST.
• Apply common spray foam to the top and bottom to provide an airtight seal around the XPS board.
• XPS must be covered by a code approved thermal barrier such as drywall. This is for occupied spaces.

How do I protect the above grade portion of the XPS on my foundation?

There are many commercially available options that are provided by others.You can install a PVC, fiber cement or stucco coating to protect the XPS board.

What about mold, mildew, and insects?

GreenGuard extruded polystyrene (XPS) foam insulation and building wraps are made of synthetic materials that are generally recognized as not providing a food source for insects, fungus, mold, or mildew. GreenGuard building materials should always be properly installed and stored.

Does your XPS foam rot?

No, XPS foam does not rot. XPS foam is designed to be used behind walls and below grade, not as an exterior finish. It will eventually deteriorate with prolonged exposure to the sun, so it needs to be covered with a cladding.
