Make your own RB Sheathing: 
Why pay a premium for radiant barrier roof sheathing when you can easily make your own for a fraction of the cost? Simply unroll our ARMA FOIL™ radiant barrier on top of your OSB or plywood and staple in place. The 48" wide reflective roof sheathing material fits perfectly.
Advantages over prelaminated decking:
- Lower cost
- More durable (Our product is much stronger then the thin layer of aluminum that comes on the pre-laminated sheeting.)
- Reduced moisture concerns (when the foil is laminated to the decking, the adhesives plug up the perforations reducing the ability of those products to pass moisture.)
Result:
Install the radiant barrier roof decking with the aluminum side facing the attic space below.
