Owens Corning FOAMULAR is an extruded polystyrene rigid foam insulation offering exceptionally long lasting R-value; superb water/moisture resistance properties; and a range of compressive strengths to meet the application needs of the architect, contractor, builder and owner. It is a unique balance of properties found only in the closed-cell structure of an extruded polystyrene insulation. FOAMULAR can be very efficiently used in construction applications such as concrete or masonry cavity walls, wall furring, insulating sheathing, perimeter/foundation walls, precast concrete and in certain applications where a higher compressive strength insulation is needed to withstand heavy loads, i.e., under concrete slabs, plaza decks, etc. FOAMULAR is also ideal for use in all types of roofing including single-ply, tapered, BUR and protected membrane roofing systems, either on new roofs or in the re-roofing of old roofs.
