RoofingFoil™ Radiant Barrier for Roofs with an Air Gap
Due to an overwhelming response in using our radiant barrier foil in roofing applications, we launched a website that is completely dedicated to covering all the options for using radiant barrier foil in roofing. Check out the roofing applications site: www.RoofingFoil.com
When installing new metal and tile roofs, incorporating RoofingFoil + Underlayment is essential for enhancing energy efficiency and durability. RoofingFoil™ + Underlayment acts as a radiant barrier, reflecting heat away from the roof surface, which helps in reducing cooling costs and maintaining a comfortable indoor temperature. It also provides an added layer of protection against moisture, preventing water infiltration and potential damage to the underlying structure. RoofingFoil™ + Underlayment not only extends the lifespan of the roof but also improves overall energy performance, making it a smart investment for new roofing projects.
RoofingFoil™ + Underlayment is approved by the Florida Building Code and Miami-Dade County, meeting/exceeding the strictest roofing codes in the USA.
Can I Install Radiant Barrier When I Have a New Roof Installed?
It depends, if you are installing typical asphalt shingles and want to add radiant barrier under the shingles without an airspace then the answer is NO. If you are installing any type of roof that has an air space (either built in by the shape of the tiles or because of a batten system), then you should most definitely install a radiant barrier! These types of roofs are usually clay tile or slate roofs, metal shingle roofs & some standing seam metal roofs. If you are using a batten system (wood nailers on top of the deck), then you will automatically have the required airspace for a radiant barrier to work properly.
Your roofing company should be able to easily install RoofingFoil™ Radiant Barrier under your new roof. All they have to do is add one additional layer on top of the waterproofing layer (below the battens). Just a few staples or plastic caps will hold the foil in place until the battens are installed over it. For most roofing applications, you should use a perforated (not a vapor barrier), so it will allow moisture to dry out and not get trapped in the roofing assembly.
RoofingFoil™ + Underlayment for Metal and Tile Roofing
Roofs with RoofingFoil™ + Underlayment are 20°F to 40°F cooler than roofs without it!
How is RoofingFoil™ + Underlayment Attached?
Installing the radiant barrier foil under a metal roof is quick and easy. Installers just roll it out and cut it with a knife. Use a few roofing cap nails (or staples) to hold in place, then install battens on top of the foil surface.
Generally a 1/2″ air space or more is ideal between the radiant barrier and the metal or tile roof.
By installing RoofingFoil™ radiant barrier under the battens, 97% of the the radiant heat that would have been absorbed by the roof deck is now reflected. Considering the expense of metal roofs, it is a small additional cost to install radiant barrier during the roofing installation.
When you stand inside this attic, it is hard to tell whether the sun is shining or not. Since so much of the heat is reflected before it enters the attic, it feels like a cloudy day. Economical, effective and energy efficient!
