From the more-things-change-the-more-they-more-stay-the-same department, after thousands of years spent evolving our dwelling places from huts into houses, the push is on for homes to return to a more environmentally friendly state once again.
It’s a trend SABIC Innovative Plastics’ growing portfolio of Lexan PC multiwall sheet products are well suited to facilitate.
As a glass replacement in skylights and roof domes for residential and commercial buildings, the Lexan material allows natural daylight to enter, SABIC said, giving ample lighting while sav-ing on electricity for artificial lighting. The company’s new Lexan Thermoclear 9-wall sheet provides U-values as low as 0.89 W/m2k, which surpasses the insulation performance of double-and triple-pane glass. It also blocks infrared radiation that can reduce the build-up of interior heat for lower energy consumption, and, at one-third the weight of a comparably sized glass panel, saves fuel in shipping and installation.
SABIC also claims that, from a manufacturing perspective, the Lexan material leaves a very light environmental footprint. “Typical operating temperatures during the sheet extrusion process are in the 240C range,” said Darrell Hughes, general manager of specialty film and sheet at SABIC. “The energy used during which the Lexan PC resin is converted into Lexan PC sheet is a fraction of the energy needed to manufacture competing flat glass.”
