• Install product perpendicular to the rafters with a 2” overlap on the seams (no taping required).
Staple the product to the rafters at 2” to 3” intervals.
• Leave a 2” to 3” gap on each side of the roof peak and a gap at the lower edge of the roof line
(within 18” OK depending on roof pitch).
• Staple to the face of the studs on gables and insure at least a 1” gap around all vents.
2. Staple to the Deck Method - Southern Zone of the USA Only
For the Regional Recommendation for this Installation Method, please verify the location of your home with
the “Zip Code Zone Locator” function at www.reflectixinc.com/zip-code-zone-locator.
• Cut the entire roll of product into 16” or 24” lengths with a miter saw (depending on rafter spacing).
• Begin at the top of the cavity. Run product flush to the decking, parallel to the rafter.
• Staple sheet directly to the deck (nails poking through sheet from above will not interfere with
performance).
• Do
not block any venting (cut around). No need to cover rafters (no loop around).
