Do Radiant Barriers Work Attic

Now there is a newer better radiant barrier product called srx superreflex.

Do radiant barriers work attic.

By reducing heat transfer from the living space into an unconditioned attic a properly installed radaint barrier can complement the energy saving efforts of traditional insulation. Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. Radiant barriers work by reducing the heat absorbed by solid surfaces through reflective insulation systems.

While not a substitute for traditional attic insulation radiant barriers may reduce your air conditioning bill by 5 to 10 according to the u s. Ultimately a hotter attic means more work that your attic insulation and ductwork needs to put in. If the radiant barrier was not there the sun would heat the roofing materials and the heat transfer would occur into the air of the attic. With new types of technology and approaches to keep homes comfortable it s natural to wonder if attic radiant barrier works.

According to the department of energy installing radiant barrier on the floor of the attic can cause problems. A radiant barrier can reduce energy loads by up to 10 in winter based on independent studies. Of energy if you live in a hot climate. Therefore if you have a cooler attic your ductwork home can become more efficient.

Srx works better than radiant barrier. Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Jordan tests lp techshiel. Damp insulation may support mold growth and eventually will lose some of its r value.

Radiant barriers are utilized to reduce summer heat gain in attics. A radiant barrier will be installed as a way to prevent your home from absorbing radiant heat in the environment causing it to reduce the amount of heat in your home as a result. Unlike fiberglass or cellulose insulation radiant barriers do little to prevent the conduction of heat or cold through the air and have no r value. 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.

It isn t the time tested fiberglass rolls of pink insulation. If so how do radiant barriers work. These thin highly reflective layers aren t designed to slow heat transfer they reflect it away before it radiates into your attic and home.
