When using rFOIL™, how can I achieve an R-30?
A system R-30 can be obtained by installing rFOIL™ in conjunction with 6″ unfaced fiberglass. In this application, the 6″ fiberglass is installed between the purlins, and the rFOIL™ is attached directly to the bottom of the purlins. The result is an attractive, consistent ceiling surface, with tremendous thermal properties.
