Roofing Radiant Barrier Felt

Increasing summer energy consumption and cooling costs.

Roofing radiant barrier felt.

Polaralum is an underlayment that goes on top of the deck underneath the shingles. They don t however reduce heat conduction like thermal insulation materials. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. Radiant solar energy strikes the roof heating the shingles felt paper and roof sheathing by conduction and causing the underside of the sheathing and the roof framing to radiate heat downward through the attic toward the attic floor.

Above sheathing ventilation with radiant barrier roof assemblies sharkskin ventilated roof mat w sharkskin ultra radiant create both above sheathing ventilation asv and sharkskin ultra radiant reflects radiant heat and creates a cooler attic which reduces cooling costs. Then roll out perforated radiant barrier foil install battens as per manufacture instructions and attach roofing product. When a radiant barrier is placed between the roofing material and the insulation on the attic floor much of the heat radiated from the hot roof is reflected back toward the roof and the low emissivity of the underside of the radiant barrier means very little. The temperature of the attic space increases and that heat is transferred to the building below.

Simply roll out roofing felt or another type of underlayment. Radiant barriers are utilized to reduce summer heat gain in attics. You are getting a new roof so why not scrape off the shingles put down roofing felt then radiant barrier search for. It is also slip resistant and won t tear.

Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction. Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills. April 19 2019 posted in. Radiant barrier is a highly reflective material typically made of aluminum which blocks the transfer of radiant heat by reflecting it away from its surface offering a permanent way to reduce your monthly utility costs.

Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation. See contractor testimonial below. With these types of roofing systems a radiant barrier can be incorporated easily and economically.
