Radiant Heat Barrier Attic Insulation

It may be an easier way to install radiant barrier but it can trap moisture between itself and the attic floor and cause the insulation to become damp.

Radiant heat barrier attic insulation.

Unlike thermal insulation like fiberglass batts or blown cellulose radiant barrier insulation has no r value and is usually made of foil. This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently. Radiant barriers are installed in the attic by stapling the material to the underside of the roof deck normally on the rafters. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.

Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. The purpose of a radiant barrier is to reduce summer heat gain and lower a home s cooling costs but not in the same way thermal insulation does. Damp insulation may support mold growth and eventually will lose some of its r value. For more information about having radiant barrier installed in your home please call 602 499 2922.

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. Barrier insulation offers radiant barrier installation anywhere in the phoenix valley. Whether you use it in a crawl space radiant floor attic or walls you ll find it easy to handle and install. According to the department of energy installing radiant barrier on the floor of the attic can cause problems.

Ideally you could actually place one radiant barrier above and a second one below your attic ceiling insulation to maximize both beneficial effect of a radiant barrier in both summer and winter. Unlike fiberglass cellulose and other traditional thermal insulation radiant barrier isn t installed on the attic floor instead it s installed in the attic ceiling just below the roof. They don t however reduce heat conduction like thermal insulation materials.
