Why You need a radiant barrier

This image was taken on a 90 degree sunny day with a standard 35mm camera. It shows a 20” X 40” cut out of the RadiantGUARD® exposing the roof decking above with the right half sprayed with a radiant barrier paint.

This image was taken immediately thereafter with a FLIR i7 infrared camera.

There is very little difference in temperature between the exposed OSB left side with no protection and the right side sprayed with the radiant barrier paint.

The temperature readings from the surface of the RadiantGUARD® average approx.30 degrees COOLER than both sides of the OSB

How does radiant barrier work?

The following images provide a visual of how effective RadiantGUARD aluminum attic insulation 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.

We DON'T recommend or use radiant barrier paints.  They are NOT true radiant barriers per the American Society of Testing and Materials International (ASTM); they are actually solutions made of paint and small metallic flakes.  They are more accurately called Interior Radiation Control Coatings (IRCC) only if they block 75% or more of the radiant heat.

​Per the ASTM, a product MUST have a radiant heat reflectivity of 90% or higher to be classified as a radiant barrier

Our RadiantGUARD® radiant barrier reflects 97% of the radiant heat; much higher than the ASTM requirement and even higher than the best so called radiant barrier paint on the market today which are HeatBLOCK Ultra at 80.5% reflectivity and LoMit-II Max 85.3% reflectivity.

Consumers of radiant barrier paints needs to be aware of some of the pitfalls of having radiant barrier sprays installed in their attic:

  • In order to cut costs, some commercial installers will actually mix a thinner paint solution with water in order to get more coverage.  Doing so greatly reduces the product's ability to block the radiant heat. 
  • Under applying the radiant barrier spray is another way contractors attempt to cut costs and that means the results are less than ideal.  In fact, the real results of most radiant barrier paint applications is typically around 20-40% reflectivity.

RadiantGUARD® radiant barrier attic installations provide a quicker ROI (return-on-investment) because they block much more heat than the radiant barrier paint products and cost less to install because they don't require any special clothing or equipment for the insulation contractor performing the installation.

RadiantGUARD® - The Best Radiant Barrier

live attic temperatures

While most homes have one of many different types of conventional insulation (fiberglass, cellulose, rockwool, etc), such attic insulation alone cannot stop the transfer of heat into your home. Conventional attic insulation is designed to absorb heat up to a certain amount. Once the insulation absorbs as much heat as it can (it's saturation level), the heat is then quickly transferred out the opposite side through the ceiling and walls into your home. And in the evening after the temperature outside has cooled down, that insulation sitting on your attic floor is still passing heat into your home require your air conditioner to work longer than necessary to cool of your house.

Because radiant heat accounts for the majority of heat gain and loss in a home, we strongly recommend our RadiantGUARD® radiant barrier attic install service to BLOCK radiant heat transfer.  With a reflectivity of 97% of the radiant heat, it offers the highest reflectivity available in the market along with a LIFETIME warranty. It is a thin double-sided pure aluminum material (about the thickness of a business card) that is very strong and durable and impossible to tear with hands due to a middle fabric scrim layer.   With perforations making it "breathable", our radiant barrier allows moisture-vapor to pass through it which is important in an attic space where moisture generated within the home collects and passes out of the attic space with attic ventilation.

other attic insulation and ventilation services we offer

Our RadiantGUARD® radiant barrier aluminum insulation BLOCKs 97% of the radiant heat that strikes its surface making it the most effective product designed to stop the transfer of radiant heat into and out of your home year round.

We don't just say our solutions work, we prove it!

★★★★★ I Shawn and the team did an excellent job...
5 out of 5 stars
Shawn and the team did an excellent job installing radiant barrier in our attic, as well as additional insulation and a solar ventilator. I chose Radiant Guard after researching several products and reviews. Their schedule is flexible and they found me 12 mo same as cash financing. My only regret is that I didn't get this done 15 years ago when I bought the house. It would have paid for itself by now. My first week's electric use was $18 lower. I could probably get that down by setting the thermostat higher but I'm enjoying temperatures that were not achievable before RadiantGuard.
★★★★★ It really does make a difference!
5 out of 5 stars
We are so happy we decided to have Radiant Guard installed in our attic. Before the install, we were struggling to get our upstairs below 76 degrees. Now we have the thermostat set to 72 degrees and it is holding to that temp! What a difference it has made for us! The company was very professional, on time, and quick. I would recommend this product to anyone struggling to cool their house or to those that want a more efficient home. It really does make a difference!
★★★★★ I would recommend them to anyone.
5 out of 5 stars
After a number of years of talking about getting radiant barrier we finally had a company called Radiant Guard out to our home to give us an estimate. They were very professional, knowledgeable and answered all my questions and concerns. They were very punctual and the estimate was swift. We were happy with the estimate and actually was less than expected. The work was done in a timely manner and also exceeded our expectations. Very thorough and cleaned up after work. We are excited to feel the comfort and see the energy savings this year! I would recommend them to anyone.

Because no one attic solution solves all energy problems, each residential attic requires a unique design solution.  Therefore, we offer the following additional installation services:

  • Blown-in Fiberglass Attic Insulation - our Attic Solution Architect may recommend adding additional blown-in insulation to bring your attic floor insulation R-Value up to R-38.  By increasing the amount of blown-in insulation, you protect your living spaces below against conductive heat gain and loss, a second method of heat transfer that occurs in an attic space.
  • Soffit and Exhaust Vent Ventilation - an extremely important feature of an effective attic is air ventilation.  A well-ventilated attic keeps a home more comfortable in the summer by carrying out accumulated static heat and protects against moist hot air from accumulating in the attic that could potentially cause rotting of internal attic structures.  As part of our free attic evaluation service, our Attic Solution Architects will determine the amount of soffit vents you need based on the cubic size of your attic and inspect existing soffit vents to determine if they are the correct size and unobstructed to allow for maximum airflow.
  • Solar Powered Attic Fan - for maximum attic air ventilation, we recommend and install Attic Breeze Solar attic fans which continuously remove attic heat and moisture buildup throughout the day creating a more comfortable home that requires less energy to cool.  And because it's solar powered, you don't add to your electrical usage and you receive a 30% tax credit on the price of the fan and installation costs.  With a lifetime warranty, you can't go wrong with Attic Breeze.

Don't delay, call us today at (972) 704-2116 and schedule your FREE Attic Evaluation and stop wasting money on excessive electric bills.  We offer day, evening and weekend appointments to fit your busy schedule.
