Sika Sarnafil announces partnership with R-50 Systems, LLC and the release of the Sarnathin-50 Roof System, an innovative high R-value roofing system for non-residential building applications.

The slim, lightweight design announcement adecreases costs of building modifications and structural retrofits, while creating more usable space for living and/or operations. Because Rich-E-Board can be produced to various dimensions, it can be used in most building and wall applications with little wasted material.
