Dicor’s DiFlex II TPO roofing resists damage to -70 F

ELKHART — Independent third-party testing has recently shown that Dicor Products’ DiFlex II TPO roofing membrane offers superior protection against cold weather cracking, the company announced today.

All polymeric materials remain flexible at moderate temperatures and stiffen to a lesser or greater extent at low temperatures. Diflex II TPO was tested to the ASTM D1790 Standard Test Method for Brittleness Temperature of Plastic Sheeting by Impact.

The test lab simulation involved dropping a six-pound hammer onto a sample of the material at a specified temperature. The sample fails if it exhibits any sign of cracking. DiFlex II TPO held up to increasingly colder temperature tests ranging from -10 F to -60° F before finally failing at -70° F.

Hail is another problem to be aware of, since some geographical areas of the United States are clearly more prone to severe hail events. Hailstones can damage a roof membrane if the surface membrane becomes brittle at the point of contact. Sometimes the hail striking the cold surface can leave cracks so small they aren’t visible until much later.

“Although no one will probably be in an RV at sixty below zero, this test vividly demonstrates how flexible and tough this membrane is,” said Tom Grubaugh, national director of OEM sales.

“RVs are constantly exposed to any number of roof damaging situations. This membrane is one more layer of security and peace of mind in that regard,” he explained. “If you are in extreme temperatures or just somewhere where the temperature drops down well below zero, you can rest easy knowing DiFlex II has got you covered,” he explained.
