XPS foam board has value in many building and insulating applications, especially in harsh environments. XPS is suitable for cold storage, insulating below slabs and slab edges, insulating foundation or cellar walls and exterior sheathing as part of the building shell. It provides water resistant layers and its durability ensures good long term payback.
Finally, XPS is widely used in weatherization work in conjunction with caulking and foam guns. Weatherization crew use XPS to help air seal soffits, insulate sill plates and seal leaky attic spaces.
Outside the insulation/auditing industry, XPS/Polystyrene is used for surf boards, manufacturing hobby models, creating architectural miniature models and of course Dunkin' Donuts coffee cups.
