The SR.P400™ panels manufactured by Styro Rail Inc. are composed of type 3 expanded polystyrene [EPS] rigid insulation and offers a compressive strength of 276 kPa [40 PSI].

• Very high compressive strength
• SR.P400™: Insulating value of RSI 0.76/25 mm [R-value 4.3/inch]
• SR.P400G™: superior Insulating value with graphite : RSI 0.85/25 mm [R-value 4.8/inch]
• Meets current building code requirements
• Closed cell - moisture resistant
• Non vapour barrier
• Permanent R-value – does not diminish with time
• Meets CAN/ULC-S701.1 standard

Install SR.P400™ insulation panels when applications require a very high compressive strength insulating material. Ideal to insulate concrete footings of all types of construction. Insulate underneath commercial, industrial and agricultural garage concrete slabs, road infrastructures, parking spaces, drainage pipes under the parking spaces of various building types. Used to insulate under arena slabs, refrigerated warehouses and concrete sidewalks.
Install SR.P400G™ panels when a higher insulation value is needed for a specified thickness.
