Product Description

Studies show that a majority of the heat that enters your home comes through the roof into the attic space and then through your ceilings into your living areas. On an average summer day, your attic space can quickly heat up to 40 degrees hotter than the outdoor temperature.?
By installing RadiantGUARD Ultima-FOIL radiant barrier in your attic, you’ll block 97% of the heat from coming into your living areas below the attic.
HOW TO INSTALL ULTIMA-FOIL RADIANT BARRIER
Today, radiant barriers are used extensively in many different industries including construction (both in residential attics and as house wrap and in commercial buildings), pharmaceuticals, agricultural and aviation to name a few.
The two primary ways a radiant barrier is?installed in an attic space are:
? Stapled to the bottom of attic roof rafters
? Rolled out over the attic floor (alone or on top of other mass insulations already in place).
INSTALLATION TIPS
? Start the installation early in the morning when your attic is at its coolest.
? Keep plenty of water on hand and drink consistently (even if not thirsty). Attic temperatures can quickly reach up to 40 degrees hotter than outdoor temperatures.
? Bring an additional lighting source to help you see in the darker areas.
? Always be aware of the attic floor joists you walk on. Some joists may “roll” when walked on if not properly secured.
? For DIYers, spread your install out over of a couple of days taking advantage of the cooler morning hours to work on the install.
? For contractors, work in groups of two or three having one person cutting the product and handing it to another person stapling it. Shared responsibilities help reduce installation time and reduce the chance of injury from moving around in the attic.
