Inspect the roof area for clutter in buildings where there is no ceiling.
- Measure the distance between the trusses. Many times, the distance will be 4′ or less. In some geographical areas, due to snow load, the distance will be as close as 2′”
- Cut pieces of the InfraStop® Reflective Double Bubble insulation, 6″ longer than the distance between the ridge pole and the bird’s mouth.”
- Staple the product to the bottom of the purlins with 5/16″ staples, 3″ to 4″ apart. Turn the edges down and staple to the side of the top cord of the trusses.”
- Staple the top of the insulation to the ridge pole and the bottom to the top plate at the wall.
- Tape any butt seams with InfraStop® Foil Tape. Make sure the tape is applied so that a proper bond occurs.
