What is a radiant barrier?
Radiant Barrier is a highly reflective, low emitting material installed at the underside surface of the roof deck and the inside surface of gable ends or other vertical surfaces in attics to reduce solar heat gain into the attic.
Why for us to install?
Because of the difficult working conditions of extreme heat in the summer, low headroom, numerous roof framing or truss webs in the way, and low light conditions.
Can radiant barrier be used as a substitute for attic insulation?
No. Radiant barriers intended to work with standard insulation, enhancing its heat resistant properties by reducing the amount of radiant heat transferred from the roof to the attic insulation.
How soon can homeowners expect a return on their investment?
Homeowners will begin to see a return on their investment immediately in terms of greater comfort and reduced energy usage. Payback will vary depending upon weather conditions, use of other energy-efficient building products, regional energy prices and thermostat settings. A radiant barrier will continue to save energy for the life of the home.
How do radiant barriers "block" heat?
The aluminum radiant barrier has two properties that enable it
to effectively block heat: emissivity and reflectivity. Aluminum's low
emissivity allows it to prevent up to 97% of the radiant heat in the
panel from radiating into the attic. Its high reflectivity allows it
to help block heat from your living space from escaping through your
roof deck to the outside."
