Radiant Barrier Foil Insulation & Reflective Bubble Insulation

RadiantGUARD® radiant barrier and reflective insulation products are beneficial in ANY application where the goal is to CONTROL HEAT.  Our reflective products are used in many industries and provide significant results when installed properly:
  • Residential homes in attics, floors, basements, crawlspaces, roofing applications and as house wraps.
  • Commercial buildings
  • Metal and steel buildings, pole barns, post frame, poultry and other agricultural buildings
  • Concrete slabs and driveway snow melts
  • Temperature sensitive storage
  • Food packaging
  • RV recreational industry
  • Transportation industry
  • Aerospace industry
  • and many more.
While researching radiant barriers and reflective insulations available in the marketplace, you will discover conflicting information, some intentionally and some unknowingly reported, causing confusion for consumers.  We, at RadiantGUARD, strive to provide consumers with unbiased honest information.  In a nutshell, reflective products can be very effective by using simple physics, and as with physics, they too have their limitations.  Please review our website information and contact us with any questions you may have about our products or competitors claims.

All RadiantGUARD foil insulation products are tested and certified by either ASTM C1313 (our foil insulation products) or C1224 (our reflective insulation products) giving you confidence in the quality of our products achieved through rigorous testing under standards accepted worldwide. For the ultimate radiant barrier, choose RadiantGUARD.

Lower Utility Bills in Residential and Commercial Buildings

Electric meterOur largest market is related to saving utility costs for residential homes and commercial buildings.

A majority of the heat gain in a home comes from the ceiling above in warmer months as a result of heat transfer from an attic space:

  • An attic space is heated in the summer months by thermal radiation from the sun (radiant heat).
  • The shingles on a roof absorb the radiant heat from the sun, and then transfer this heat (via conduction) into the attic space below.
  • This heat is then radiated from the roof decking into the attic space and subsequently into your living space below resulting in increased temperatures and added strain on your air conditioning units struggling to maintain a comfortable and consistent temperature.

While most homes have one of many different types of conventional insulation, conventional insulation alone cannot stop the transfer of radiant heat into living spaces.  Conventional insulation is designed to absorb heat up to a certain amount.  Once the conventional insulation reaches its holding capacity (saturation), the heat is then transferred completely through into the living areas below.

A RadiantGUARD® reflective foil insulation BLOCKS 97% of radiant heat transfer when placed between the roof and the living spaces below.  By either

  • stapling to the underside of a roof decking or rafters, or
  • laying over the attic floor over existing insulation

our breathable foil insulation can significantly improve the comfort of your home, reduce strain on your AC unit and lower your monthly utility bills.

The following images provide a visual of how effective RadiantGUARD® reflective product is against blocking radiant heat from a residential roof deck from entering an attic space. The images were taken from the attic floor viewing upward to the RadiantGUARD® attached to the underside of the roof decking.

This image was taken on a 90 degree sunny day with a standard 35mm camera. It shows a 20” X 20” cut out of the RadiantGUARD® exposing the roof decking above.


This image was taken immediately thereafter with a FLIR i7 infrared camera. The temperature readings from the surface of the RadiantGUARD® foil insulation average approx. 100 degrees. The temperature readings of the roof decking surface average approx. 130 degrees; 30 degrees hotter than the surface of the RadiantGUARD®.
