Glass-reinforced PVC has been made into sheet and fence profiles, but problems with porosity have kept it out of window profiles until now. Rehau AG in Rehau, Germany, developed a glass-filled PVC track for a car door seven years ago. Rehau later developed a glass-filled PVC formulation, called Rau-Fipro, for window profiles. Customers began shipping the first windows using Rehau’s Geneo profiles with glass-reinforced cores on July 1. Fiberglass adds so much strength that windows made of the new profiles meet a high burglar resistance rating (Class 2) without steel reinforcements—a big cost saving. Without steel, windows also weigh 40% less and have better acoustic insulation. They also reportedly get the highest energy efficiency rating in their class. Rehau is quickly ramping up German production of Geneo profiles but has no plans yet to make them at its plant in Winnipeg, Alberta. +49 (9283) 77-00 • www.rehau.com
