Bayer MaterialScience LLC (Pittsburgh, Pa., USA) announced on Oct. 19 that its Baydur PUL 2500 polyurethane glass-reinforced resin system for pultruded window frames and stiffeners is more insulating than aluminum and steel, tests show. The thermal conductivity of the Baydur PUL 2500 resin system is listed in the National Fenestration Rating Council’s (NFRC) most recent publication of thermophysical properties.

Baydur PUL 2500 composite system, with its thermal conductivity value of 1.522 Btu·in/hr·ft²x °F, is 729 times less thermally conductive than aluminum and 228 times less thermally conductive than steel.

“Commercial and residential window manufacturers are constantly redesigning and improving their products to meet the ever-tighter energy performance demands of their customers. We developed the Baydur PUL 2500 composite resin system to help those manufacturers make more highly insulating residential and commercial windows,” said Craig Snyder, market channel representative, Bayer MaterialScience.

“In addition to better conductivity ratings,” Snyder continued, “the Baydur PUL 2500 system also offers favorable flexural modulus characteristics critical to solid framing materials. Its strength-to-weight ratio is very much comparable to those of aluminum and steel, which makes Baydur PUL 2500 an excellent, strong, corrosion-resistant, lightweight and better insulating alternative to metal for framing and stiffening vinyl windows.”
