Insulation

An Uninterrupted Blanket of High Performance Insulation

OSB (Oriented Strand Board) is laminated to thick expanded polystyrene foam to become one unit. The panel is then nailed into both the decking and timber rafters.

Designed especially for exposed beam roof systems, R-Wrap Panels are a combined, one-step application of insulation and sheathing. Expanded Polystyrene Foam (EPS) contains no CFC's and provide a highly efficient blanket of roof insulation. R-Wrap is available in 4'x8' and 4'x16' panels.
