Roof Radiant Heat Barrier

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

Roof radiant heat barrier.

Why radiant barriers require an air space. Ultimately a hotter attic means more work that your attic insulation and ductwork needs to put in. 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. The roof still is gaining and loosing heat.

The radiant barrier is basically just directing the same amount of heat away from the attic and the attic insulation. A radiant barrier works best when it is perpendicular to the radiant energy striking it. The radiant barrier reflects 95 of the radiant heat back to the roofing materials which then emits over 90 of the heat out the roof almost instantly. Our do it yourself radiant barrier will make your home more comfortable and energy efficient.

Radiant barrier paint performed the worse providing a heat decrease in the conditioned space of around 19. Double reflective insulation roll with staple tab edge for a versatile insulation product select for a versatile insulation product select reflectix insulation to help save energy costs throughout the home.

Florida solar energy center conducted a study on radiant barrier and shingle temperatures and found that the roof increased in temperature by only about 5 degrees at the hottest point of the day when the heat was entering and exiting the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.

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.
