Reduce the risk that weather holds for commercial plaza roof decks. Installing PLAZAMATE™ XPS Insulation above waterproofing membranes in plaza deck applications helps membrane resist the freeze-thaw cycles that can inflict damage during and after construction.
PLAZAMATE™ Extruded Polystyrene (XPS) Foam Insulation is a STYROFOAM™ Brand Insulation designed for installation above waterproofing membranes in plaza deck applications. PLAZAMATE Insulation helps the roof membrane maintain a steady temperature, minimizing the harmful effects of freeze-thaw cycles weathering and physical damage during and after construction.

1 Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since STYROFOAM™ Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformation.
