Rigid extruded polystyrene insulation panel for walls.

Foamular 250 extruded polystyrene xps provides continuous insulation in insulated concrete sandwich panel walls in masonry unit cavity walls or when used with non penetrating surface mounted furring systems over masonry or concrete walls. Foamular 250 retards the transmission of water vapor and moisture in masonry walls. As far as cost and r value goes xps is the middle option of the three. Xps is a recyclable insulation that s mostly used in walls and below grade applications.

Panels are 2 x4 with tongue and groove edges on the 4 length. Thermal performance is rated at r6 6 5 per inch but don t count on that if your winters are cold for the reasons we re about to explain. Pir polyiso or iso is a thermoset plastic product typically produced as a foam and used as rigid thermal insulation panel most often with aluminum foil facing. It s also virtually impervious to moisture preventing loss of r value due to moisture penetration.

Foamular 150 rigid foam xps insulation for exterior walls contains hundreds of millions of densely packed air cells to provide excellent thermal performance.
