How Radiant Barrier Works in Attics. Radiant barriers work by blocking radiant heat from being absorbed into our homes, garages, sheds, etc. resulting in a more comfortable and energy efficient space.

Create a green energy barrier by laying the radiant barrier foil out OVER the existing insulation on the attic floor. This method keeps heat out in summer and heat in during winter months, making it ideal for year-round benefit.

AtticFoil radiant barrier supply sells foil insulation for blocking heat in hot and cold climates.

When the radiant rays from the sun hit a gable wall, it absorbs that radiation and re-radiates it across the attic, just like the slopes of the roof do. Therefore, you should use a radiant barrier in this area to block radiant heat gain.

A radiant barrier installed in the attic will help keep the radiant heat emitting from the home from hitting the roof. The result is a cooler roof deck, which will reduce ice damming. Many customers have seen a significant reduction in ice damming after installing AtticFoil™ radiant barrier.

Radiant barrier is your first line of defense (against radiant heat) and traditional attic insulation (fiberglass or cellulose) is the second line of defense against conductive heat gain. Bottom line: you need a radiant barrier in addition to your traditional insulation.

AtticFoil™ Single Sided Radiant Barrier Foil + Whitestill reflects 97% of radiant heat from the foil side, but has the addition of a white vinyl-like material on the second side for aesthetic purposes.

By minimizing airflow within the insulation and minimizing radiant heat loss/gain from your attic, a radiant barrier will make your home more comfortable and efficient overall. Watch the video below to learn why you need to do this immediately to stop the biggest energy mistake in your home.

Meanwhile, the radiant barrier foil will reflect 97% of the radiant heat transfer. Radiant barrier foil is actually the best radiant barrier you can use; you can either install it yourself or hire a professional installer who uses our foil insulation.
