Don't Let The Heat Take a Bite Out Of Your Energy Bill Fight Back With Radiant Barrier

 

Radiant barriers were originally developed by NASA to protect spacecraft and astronauts from the extreme temperatures in space. Since then, the product has undergone extensive research and development and is now available for residential, commercial, and industrial use to help homeowners and businesses reduce their energy costs and protect the environment.

Radiant barriers are installed in buildings to reduce summer heat gain and winter heat loss, and hence to reduce building heating and cooling energy usage. the benefit of attic radiant barriers is primarily in reducing air-conditioning cooling loads in warm or hot climates.

Radiant Barrier is a low emissivity reflective coating that is sprayed on your attic ceiling. See insulation diagram above. Radiant Barrier reflects the sun's heat away from your home, subsequently keeping your attic cooler, and your electric bills lower!

• Our Radiant Barrier coating reflects over 81% of the sun's heat away from your home Lowers the temperature in the attic 20 - 40 degrees!

• Permeable - does not trap moisture - allows water vapor to permeate.

• Excellent investment - reduces heating and cooling costs by as much as 15% (as certified by an independent testing laboratory).

• Greatly improves interior comfort levels.

• Improves efficiency of existing insulation. (makes R-19 work like an R-35).

• Only economical way to retrofit radiant barrier to existing structures.

• May be easily applied to side walls and garage doors.

• Unaffected by rodents, birds and insects.

During the winter 50-75% of heat loss is through the ceiling/roofing system and 65-80% of heat loss through the walls is radiant. During the summer, 93% of the heat gain in your attic is from radiant heat.

We have found spray-on radiant barriers are often more cost effective than foil barriers, however, our Energy Consultants will work with you to determine the best type of radiant barrier for your home and budget. Our goal is to install a product that will deliver you the best results and the quickest return on investment. Saving you money now and for years to come.

Another aspect of radiant barriers are important when the air handler or air-conditioning ducts are installed in the attic space. The roof applications of radiant barriers can result in lowered air temperatures within the attic space, which in turn can reduce heat gains by the air flowing through the ducts, thus increasing the efficiency of the air-conditioning system.

Reflect Up To 81% 0f The Sun's Energy

How do radiant barriers work?
All materials used in building construction brick, stone, asphalt, paper, and so on, regardless of their color, adsorb and then emit, (give off), thermal heat. On a sunny summer day, solar energy is absorbed by the roofing materials and roof sheathing, temperatures can reach as high as 140 - 160 °F. This absorbed heat radiates downward toward the attic floor.

When a radiant barrier is placed on the underside of the roof sheathing, much of the heat radiated from the hot roof is reflected back outside. This makes the attic insulation cooler and thus reduces the amount of heat that moves through the insulation into the rooms below the ceiling

Not Only Saves Money
Saves Energy As Well

How does a radiant barrier differ from conventional attic insulation?
Radiant barriers reduce the amount of heat that is radiated into the attic which lowers attic temperatures, conventional insulation traps the heat that is already in the attic and slows down, (doesn't stop it, simply slows it down) the heat transfer into the house.

Radiant heat is generated by many of the things around us. In summer, the sun is the primary source of radiant energy. It heats the exterior of your home, and this heat eventually is conducted into the interior. In this care, the spray on barrier helps keep your home cool by reflecting back the suns radiant energy and preventing heating build-up in your attic.

A single coat of our spray applied to the underside of your roof deck will block up to 81% of the sun's radiant heat from entering the attic of your home..

And in winter, the same radiant barrier will reflect back up to 65% of the heat that tries to escape from your home through the attic.

Yet unlike foil substrates ,installed with staples and tape to bottom of rafters thereby cutting of ventilation to open space of attic ,without labor intensive retrofit to each and every roof vent to allow proper ventilization,radiant barrier spray can be applied evenly over entire surface, with no gaps or holes,tape,or staples,to come lose,tear, causing maintainence, in occurance of a strong draft,with a breezey or sudden change in wind direction,that does occur in a properly vented attic.And because it is sprayed on, it can be appllied to new and exsisting structures,with certainty to hard to reach areas more economicly.

Existing or New Homes
The U.S. Federal Trade Commission (FTC) defines "home insulation" as "any material mainly used to slow down heat flow" (16 CFR Part 460.2). ENERGY STAR considers insulation to be products or materials that meet the FTC's definition of "home insulation" and are used to insulate a whole wall, ceiling, or floor. These products include, but are not limited to: fiberglass, Cellulose, mineral wool, whole-wall spray foam, rigid foam board, cotton fiber batts, and foil radiant barrier products.

What kind of testing has been performed to verify this products effectiveness?
Independent research labs in the U.S. And Europe have tested spray-on radiant barriers and have confirmed their low emissivity values (the amount of radiant heat that can pass
through it). Many utility companies around the United States have validated these findings by offering significant rebates for customers that install radiant barriers - check with your
energy provider to see if you qualify.

We know that Denton County has a rebate program.


Study Shows 23-Degree Temperature decrease from in Attics with Radiant Barriers.

Appalachian State University also found that radiant barriers improve air conditioning efficiencies.
By: Jean Dimeo

The Appalachian State University Energy Center in Boone, N.C., recently announced the results of a case study to measure the benefits of adding radiant barriers in home attics.
Key findings of the study include:
--A 23-degree F drop in the peak attic temperature.
--A 20 percent reduction in the AC unit's run time during the seven hours of peak attic temperatures.
--A 57 percent efficiency improvement in the cooled air delivered through the air ducts.

"This particular study showed the installation of a radian barrier in an attic can make it easier for your air conditioner to do its job in the summer heat," Jeff Tiller, a professional
engineer at the university, said in a statement. "That translates to lower electricity usage, which also impacts the carbon footprint of homes."

The research team utilized two side-by-side four-bedroom model homes built by Centex Homes in Charlotte, N.C. A total of 61 sensors were installed inside and outside of the
dwellings to gather data.

"We're very please that this study validates the significant energy saving benefits," said Clayton Traylor, who head environmental affairs for Centex.

How long does this product last?
Our spray applied radiant barrier has the durability of a premium latex paint. It should give 25 years of service and more in an enclosed attic for long term energy savings!.

Does the energy-saving effect wear off over time?
Over time the accumulation of dust and grim on foil radiant barriers will diminish its effectiveness. However, since our sprayed radiant barrier coating is installed on the underside
of your roof deck, it is safe to assume that minimal dust & grim will accumulate for extended energy savings with no maintenence issues!
