Radiant Barrier & Reflective Insulation

RadiantGUARD® radiant barrier and reflective insulation reduce heating and cooling costs by reflecting radiant heat back to the heat source making your home more comfortable both in the summer and winter months all while lowering your energy consumption saving you money year round.

Our radiant barrier and reflective insulation products are ASTM certified (including ASTM e85) and reflect between 95-97% of radiant heat back to its source when installed properly using our recommended installation instructions found on our How To Install page.

RadiantGUARD® Benefits

Upwards of 93% of ceiling heat gain in summer months can be attributed to heat from the attic space above caused by radiant energy transferred by the sun.  The radiant heat from the sun is absorbed by roofing shingles and transferred to the roof decking below and into the attic space.  Conventional insulation absorbs much of this heat and once its saturation point has been met, this heat is then transferred to the living spaces below.

When stapled to the bottom of roof rafters in an attic space, a RadiantGUARD® foil insulation can block 95-97% of the radiant heat from the roofing surface and thereby  lower overall attic temperatures by almost 30 degrees bringing the attic temperature closer to the true outdoor temperature or even lower.  By lowering the temperature in your attic, you can reduce the amount of heat transferred to your living spaces below by up to 50% giving you greater comfort in your home and lessening the strain your air conditioning unit.

Looking for ways to insulate your home and reduce energy costs? A wide selection of materials to suit many of your insulation needs is available right here at Radiantguard.com. Whether you are looking for a product for your attic or for your concrete floor, we have the right barriers to keep your home comfortable and have you saving money as well. We also have several articles at your disposal on common questions and information to help you with your purchase. Our popular Standard, Premium, and Ultima foil Radiant GUARD products are two-sided and consist of a 99% pure aluminum surface with a poly fabric center. The aluminum provides reflectivity, while the poly center provides strength and tear resistance that is needed for the product to perform well. This versatile radiant barrier can be used for new or retrofit roof designs, radiant heat flooring systems, or house-wrapping. The minimal air space needed to work most efficiently is nothing compared to the effectiveness of this product over time. Foil products are especially useful in attics as insulation overlay, laid over the attic floor, stapled to the underside of roof rafters, or as part of the roof decking system. It is incredibly easy to install and requires no special tools or special protective clothing needed.

Radiant Energy Barrier

All our radiant energy barriers are lightweight and will remain unaffected by changes in humidity. The Ultima strength comes in solid and all strengths come in the perforated version, it just depends on the uses you have for them. Perforated versions are needed when you are using the radiant barrier in the attic, as houses need to breathe and moisture vapor rises and needs to pass through. Otherwise you could trap the water in the air resulting in water damage to your attic floor and rafters. You can learn more about the different version by visiting our perforated radiant barrier versus non-perforated solid vapor barrier. Reflective aluminum foil insulation is easy to install and requires no maintenance. With the reduction in heating and cooling costs reflective insulation pays for itself rather quickly. Our premium radiant barrier should be used when the project calls for a little stronger material, and our ultima product is our strongest grade aluminum foil. It should be used for contractor-grade applications and is ideal when you need the ultimate in strength and durability.
