Lightweight Insulated Cellular Concrete Roof System
The Sarnafil Lightweight Insulated Concrete (LWIC) Roof System utilizes Sarnafil feltback G410 fiberglass reinforced thermoplastic membrane adhered to lightweight insulated concrete. LWIC is a mixture of Portland cement, water and preformed foam. The result is a lightweight substrate with a compressive strength of 120 PSI- 300 PSI. The characteristics of LWIC make it an excellent substrate for adhering Sarnafil feltback G410 membrane, resulting in a roofing system with high wind performance characteristics. LWIC can be utilized on both new construction and reroofing applications.
