Before you specify it

  • From the data sheet: the board is combustible, and a protective or thermal barrier is required as specified in the building code. Kingspan does not recommend GreenGuard XPS for exterior walls over 6 stories, and asks that board left exposed outdoors be covered within 60 days against UV.
