Polyethylene makes a good roofing product, many high end synthetic/composite roofing materials are composed of polyethylene. CeDUR is composed of polyurethane. Polyurethane is very light weight, adds insulation value to a home, and allows CeDUR to incorporate a proprietary fire retardant that is manufactured directly into the final product.
In the event of a fire, flames spread from roof to roof, with embers from the fire being a major cause of traveling fire damage. CeDUR's proprietary technology will self extinguish flames and does not allow a flame to propagate on the surface of the roof.
Natural wood cedar shakes ignite at 375 degrees Fahrenheit. During CeDUR’s Class A burning brand test at a certified burn center, CeDUR reached temperatures as high as 1,400 degrees Fahrenheit without igniting.
Unlike most roofing materials that require a fire resistant underlayment during installation to achieve the Class A Fire Rating, the CeDUR product itself is Class A Fire Rated. In terms of installation, you can lay CeDUR shakes down on top of 30# felt and you have a Class A Fire Rated roofing system.
CeDUR is the perfect alternative for homeowners and industry professionals looking for a fire safe wood shake roofing alternative. CeDUR is also a trusted alternative to asphalt shingles, polymer, composite, and synthetic roof materials. Using a roofing material that self-extinguishes flames in the event of a fire has the potential to save properties and save lives. This fire retardant technology is patented and proprietary to CeDUR.
