Zip system roof and wall sheathing panels are zip system roof and wall sheathing panels are oriented strand board osb structural panels with built in protective overlays that eliminate the need for building wrap or roofing felt. One reason contractors avoid using foil backed osb in wall systems is because it is hard to create the air gap needed for foil backed osb to work properly. Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes.

We take a look at how radiant barriers work the different types of radiant barriers and some of the. The plywood panels can be purchased in either 15 32 or 19 32 4 x8 sheets. Similarly foil backed osbs installed on the attic floor may. Both products come with a limited lifetime warranty.
