Product Details

SHEERFILL® Architectural Membranes are lightweight, meaning they require fewer support structures and the use of long-span cables enables large open spaces compared with more traditional construction methods SHEERFILL® allows diffused natural light into the space below while rejecting heat for increased energy efficiency. Built to last, our architectural membranes provide 30+ years of performance with easy cleaning and low maintenance. The fiberglass and PTFE are virtually unaffected by UV so you can be confident your project will retain its aesthetic appearance for the long term. The PTFE surface enables the easy removal of dirt and contaminants with just the action of natural rain. Additionally, SHEERFILL® provides outstanding safety with low flame spread and smoke generation for a Class A fire performance.
