Protecting Your Energy Costs

Studies have shown that up to 93% of ceiling heat gain in summer months occurs from radian heat transfers from attics heated by radian energy from the sun. Roof shingles and decking absorb radiant heat generated by the sun and transfer this heat into attic spaces heating up existing insulation. Once this existing insulation meets its saturation point it then radiates this heat to all surfaces within the interior of the home (ceilings and walls).
Radiant barriers BLOCK almost ALL of this radiant heat.
RadiantGUARD® double-sided radiant barrier products are the leading products on the market used by home owners, new home builders, and agricultural and manufacturing enterprises. Our radiant barrier foil insulation products are made from 99% pure aluminum making them the best at blocking 97% of the radiant heat that attempts to enter building structure in the summer months or escape in the winter months helping save energy year round.
In the summer months, our radiant barrier products can reduce attic temperatures by up to 30 degrees when installed to the underside of roof rafters. Lowering attic temperatures provides a significant benefit by reducing air conditional loads and energy usage. Radiant barriers can also:
- Reduce heat transfer from attic to living spaces by up to 50%
- Extend the life of air conditioning units, and
- Increase the comfort level of a home.
RadiantGUARDR radiant barriers can be installed in any of the following locations:
- Stapled directly to roof decking or draped over roof rafters before decking is applied
- Stapled to the underside of roof rafters in the attic
- Rolled out over existing insulations on attic floor, or
- Stapled to exterior as a house wrap before brick or siding is applied
