radiant barrierRadiant Barrier Reflective Foil 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.

 

Lower Utility Bills in Residential and Commercial Buildings

Our 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.

Radiant Barrier R-Value

April 10, 2015

We're often asked "What is the r-value of your Ultima-FOIL radiant barrier?"  The answer is simply zero because radiant barrier doesn't work like an R-Value rated product. So Exactly What Is An R-Value? Simple put, an R-Value is the measurement of an insulating or building material's ability to resist the transfer of heat through itself.  As an R-Value material's thickness increases, so does the R-Value which means, the material's resistance to heat transfer is better. So, in essence, a product with a higher the R-Value is better than a similar product with a lower R-Value.   Once an R-Value rated insulation reaches its absorption capacity, the insulation then starts to transmit heat from itself directly into those same areas you where you were trying to control heat....

Top Radiant Barrier Facts

June 16, 2014

Looking for a quick overview of the most important radiant barrier facts to separate fact from myth?  Below are the top radiant barrier facts to help get you started.  Want more info? See our Radiant Barrier FAQs. RadiantGUARD® radiant barriers BLOCK 97% of the radiant heat, almost 30% MORE heat than the best reflective paint. Read more about reflective radiant barrier paint. Radiant barriers do NOT have R-Values but DO increase the R-Value of your existing insulation if already in place. Read more about radiant barrier and insulation r-values. Radiant barriers MUST have at least a 3/4" air space on at least one side for them to be effective via the properties of reflectivity and/or emissivity. You cannot lay a...
