Insulation with a radiant barrier attic.

They don t however reduce heat conduction like thermal insulation materials. Damp insulation may support mold growth and eventually will lose some of its r value. A radiant barrier is designed to increase the effectiveness of your thermal envelope. 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.

Radiant barriers are installed in the attic by stapling the material to the underside of the roof deck normally on the rafters. With new types of technology and approaches to keep homes comfortable it s natural to wonder if attic radiant barrier works. These thin highly reflective layers aren t designed to slow heat transfer they reflect it away before it radiates into your attic and home. According to the department of energy installing radiant barrier on the floor of the attic can cause problems.

It s versatile and will save energy throughout your home. Installing radiant barrier under the roof decking is the preferred method versus on top of the insulation because it gives an air gap for the heat to escape to the ridge vent without creating a potential moisture problem between the radiant barrier and the attic floor. By reducing the amount of radiant heat reaching the insulation in your attic the insulation remains cooler and is able to keep your home more comfortable. This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently.

The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. It is meant to supplement insulation not replace it. Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Radiant barrier should always be installed to work with the soffit and ridge.
