St. Louis-based Solutia Inc.’s Saflex unit introduced SilentGlass Technology, an acoustic interlayer system that cuts outdoor noise by up to 50 percent, according to a company release. The system combines three interlayers designed to separate and disseminate sound waves including an interlayer that transforms sound energy into heat energy that quietly dissipates, according to the release. Targeting sounds in the 1000 Hz or cycles per second, to 3000 Hz range such as car horns, barking dogs, amplified music and aircraft, the interlayers can be used in airports, hotels, health care and educational facilities, and housing and offices near transportation corridors. It also provides protection against forced entry and blocks 99 percent of ultraviolet light, according to the release. SilentGlass Technology is available through Saflex’s preferred fabricator network.
