radiant barrierRadiant Barrier 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,
  • Temperature sensitive storage,
  • Food packaging,
  • RV recreational industry,
  • Transportation industry,
  • Aerospace industry,
  • and many more.

While researching radiant barrier foil 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® radiant barrier 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 Reduces Ice Damming

September 17, 2015

Winter will be here before you know it and that means you need to be prepared for snow and ice and the potentially damaging effects it can have on your residential home. 

While the visual effects of an ice dam are undeniably beautiful, the physical effects to your roofing system can be extremely damaging to a roof, gutters, paint, drywall, and your underlying framing structure.  This damage can also eventually lead to the growth of dangerous molds.

Radiant Barrier Paint vs. Radiant Barrier Insulation

May 06, 2015

While researching radiant barrier insulation online, many consumers are coming across paint products erroneously marketed as radiant barrier paint which are intended to be sprayed to the underside of the roof rafters to lower the emittance of radiant heat from the roof decking into the attic space.  While these products do help to lower the amount of heat that radiates into the attic space, the use of the term radiant barrier paint is false advertising and these products don't offer near the protection against radiant heat as a radiant barrier foil insulation product.

Foil Insulation Increases R-Values & Lowers Bills

May 05, 2015

Many consumers are familiar with them term R-Value and how it relates to the effectiveness of a conventional attic insulation product.  While foil insulation doesn't have an R-Value (you can read more about radiant barrier r-values here), it does INCREASE the performance R-Value of your existing R-Value rated insulation.
