6Measuring for Coverage
- Measure the outside of the building to get the
area - Determine the pitch of the roof
- Multiply the area by the Roof Pitch Factor (rise
and run multiplier) or the pitch of the roof - Determine area of gable by measuring the length x
height and divide by 2. - Example Area of Building is 2,500 sq. ft. Roof
Pitch is 512 two gables (20W x 8H 160 sq.
ft.). Totals 2,500 x 1.08 2,700 sq. ft. 160
for gables 2,860 of radiant barrier will be
needed
7Installation on Roof Rafters
- Three Methods
- Side to Face
- Face to Face
- Inset Staple Only for Cavities sharing Mass
Insulation - Staples
- ¼ or larger staples
- Galvanized or stainless steel staples
-
Question What kind of roof system is inset
stapling acceptable?
Answer Only sections where the radiant barrier
and the insulation share the same rafter (e.g.
2 x 10 vaulted roof).
8Installation on Roof Rafters
- Procedure
- Determine the width of the rafters (16 or 24
o.c.) - Is it a Gable or Hip Roof?
- For the roof area, measure from the peak of the
roof to the soffit - Cut the number of pieces of radiant barrier
- Printed Side Faces Down - Metalized Side Faces Up
- Staple one tab to a rafter
- Pull the other tab to open the layers
- Staple every 4 to 8
- Fold over each end to encapsulate the layers
Question Why fold the ends?
Answer To enclose the ¾ reflective airspace to
attain the rated R-value.
9Installation on Roof Rafters
