To make it easy to eyeball how level the material is as you blow it in screw depth guides to joists throughout the space.

This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently. Fasten blocking around the hatch or door to allow the material to be installed around this area without escaping. The attic overheats the house becomes warmer and your air conditioning bill goes through the roof. The first is stapling foil to the bottom of the roof rafters the second is laying it out over the existing attic ceiling insulation.

The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface.

Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills.
