Tpo Roof Sri
Gaf analyzed membrane samples from roofs across the us and studied thickness over scrim surface cracking and the ability to repair aging tpo membranes.
Tpo roof sri. Sri a well known and highly respected laboratory that has done testing with ul nrca and mrca independently obtained various rolls a total of 45 in all of all of the major tpo brands. Throughout 2013 and early 2014 structural research inc. Tpo roofing systems thermoplastic polyolefin tpo single ply roofing membranes are among the fastest growing commercial roofing products and have gained praise across the industry for their many performance and installation advantages. Carlisle s sure weld tpo membranes have the industry leading octaguard xt weathering package for enhanced long term weathering.
Heat welded seams provide superior strength. Jm tpo 60 mil result dynamic puncture d 5635 n a pass 25 joules static puncture d 5602 n a pass 44 lb 20 kg impact resistance of bituminous roofing systems d 3746 n a pass minor indentations reflectance c 1549 n a 78 e 903 n a 80 emittance c 1371 n a 0 87 e 408 n a 0 96 sri e 1980 n a 95. A recent study of everguard tpo roofs installed between 8 and 16 years ago found they all performed above astm standards for newly manufactured tpo. Sri conducted a variety of astm physical property testing including thickness above scrim and weld strength which showed that the four tpo brands exhibit relatively similar performance on these tests.
