Products / Sentinel P150

Sentinel P150 is a 60 mil bare-backed thermoplastic PVC roof membrane reinforced with a weft-inserted polyester fabric encapsulated on both sides, with a minimum 30 mil thickness over the scrim. The same line is published as Sentinel P200 (80 mil) and as the fleece-backed Sentinel P150 HFB and P200 HFB, which carry a 5.5 oz/yd2 heavy fleece backing; bare-backed rolls are 10 or 5 ft wide by 100 ft long, in white, gray and tan. Each data sheet states the membrane meets ASTM D4434, Type III, and lists an initial Solar Reflectance Index of 108 for the white sheet under ASTM E1980. It is installed mechanically attached, fully adhered with Sentinel H2O or Sentinel S Bonding Adhesive, or induction welded, with all laps heat welded.
