Frequently Asked Questions
How do I install XPS on my basement wall?
- Glue the board to the concrete wall using a minimum of 5 large sections of adhesive — 4 corners and one center. Apply pressure until the glue holds. Compatible adhesives are listed in TB11. Kingspan recommends Loctite Power Grab Adhesive.
- Alternatively, fasten the board with 5 Plasti-Grip PMF Anchors from TRUFAST.
- Apply common spray foam along the top and bottom edges to create an airtight seal.
- XPS must be covered by a code-approved thermal barrier such as drywall in occupied spaces.
