OPEN-RIDGE INSTALLATION METHOD
The Open-Ridge method, or synonymously know as the Staple-Up method is the standard method used most often. In this method, the radiant barrier foil is stapled on the bottom of the rafters inside the attic. During the installation you will work to leave a gap at the top and bottom of all rafters and a space is left along the ridge (peak), hips and valleys and any attic vents. The spaces and slits are created to allow for continuous air flow through the attic, as if the radiant barrier foil was not even there.
