InsulationStop’s Attic Radiant Barrier Foil

Attics are the primary source of heat transfer in a home. The overhead sun constantly emits radiant heat that hits the roof and is absorbed into the attic. As the attic temperatures rise, more radiant heat is absorbed and transferred by the ceiling above down to you and into your living space.

You can stop this transfer of radiant heat however. Aluminum is one of the most highly reflective materials on Earth. Radiant barriers are highly reflective sheets of aluminum foil woven to a mesh or scrim for thickness, strength, and durability. Installed correctly, and they can lower your attic temperature up to 30 degrees.

At InsulationStop.com, we supply the BEST radiant barrier on the market at the LOWEST price. Our attic radiant barrier is Energy Star Approved and at a 8 mil thickness and over 33 lbs. Weight (per 1000 sq ft). it is the heaviest in the industry.

If you are planning on installing the radiant barrier on the attic floor you only need to measure for the square footage you intend to insulate. If you are stapling the insulation to the rafters you need to account for the pitch of the roof. First measure your attic square footage. Then determine the pitch or slope of your roof. Use table to find your Pitch Factor. Multiply the Square Footage x Your Pitch Factor = Square Footage of Radiant Barrier Required. Don’t forget to include any gable or other end walls. They will need to be insulated as well.
