XPS Type VI 40 PSI Drainage Board

GreenGuard Drainage Channeled Insulation Board is a Type VI extruded polystryene foam insulation board designed for installation above waterproofing or roofing membranes in plaza decks and Protected Membrane Roofing Assemblies (PMR.) Sheets are 4 ft. x 8 ft. x 2 in. thick with 1 in. x 1 in. drainage channels along each 8 ft. long edge and a 2 in.wide  x 1 in. deep drainage channel in the center.
Installing insulation above the roofing membrane minimizes the harmful effects of freeze-thaw cycles, harsh weathering and ultra-violet light to which the roof membrane would normally be exposed.
