XPS Foam Board TDS
Technical data sheet for Green Insulation XPS foam board — closed-cell extruded polystyrene in 250, 350 and 500 kPa grades, 1" to 4" thick, 4 × 8 ft.
XPS Foam Board is a closed-cell extruded polystyrene insulation board manufactured by Green Insulation Private Limited, a sister concern of Petroseal Enterprises, and supplied nationwide through Petroseal. The closed-cell structure gives low thermal conductivity, very low water absorption and high compressive strength.
Choose the compressive grade for the imposed load: 250 kPa for light roofs, 350 / 500 kPa for trafficked podiums and under-floor use. Pair with PetroGrip waterproofing — below the boards for inverted roofs, or above with screed and a separation layer for conventional build-ups.
