Radiant Heat Barrier For Attics

Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes.

Radiant heat barrier for attics.

Some studies show that radiant barriers can reduce cooling costs 5 to 10 when used in a warm sunny climate. Radiant barrier installation attic radiant barrier installation most of the heat entering a home comes through the roof. For a versatile insulation product select reflectix insulation for a versatile insulation product select reflectix insulation to help save energy costs throughout the 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.

But there are actually many cons to radiant barriers that are not discussed. 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. Whether you use it in a crawl space radiant floor attic or walls you ll find it easy to handle and install. The reduced heat gain may even allow for a smaller air conditioning system.

Radiant barrier should always be installed to work with the soffit and ridge. We take a look at how radiant barriers work the different types of radiant barriers and some of the. Radiant barriers are more effective in hot climates than in cool climates especially when cooling air ducts are located in the attic. A radiant barrier can lower heat transfer from attics to the building below keep the attic space cooler and lower cooling costs by up to 17 in warmer climates.
