Insulperm, Poured-In-Place

Insulperm is a patented, premium-quality nominal 1 pcf- (16 kg/m3) density expanded polystyrene insulation board. It serves as the primary insulator and, when used in a stair-stepped configuration, is the base for the system’s slope-to-drain capability. Configured to give the system composite strength and ensure release of moisture vapor, Insulperm is a lightweight expanded polystyrene insulation board that adds little dead load to the assembly.

• Supplied in 2-foot by 4-foot (.61 m x 1.22 m) boards in thicknesses from 1-inch (25 mm).
• Designs used with concrete substrate construction may allow unlimited thickness of Insulperm Insulation Board.
• Stanadard ZIC System requires a minimum 2-inch thickness of ZIC over the top of Insulperm Insulation Board.
