"A radiant barrier coating will save 10-15% of AC costs" - U.S. DEPARTMENT OF ENERGY
Despite what some of the "naysayers" may say about radiant barrier......it does work, IF AND ONLY IF it is done correctly. This is an email from one of our customers, Jim Lodwick...see Jim's email.
Hey -
Thanks for the break-down. Almost every house built in NWHills had cedar shake roofs when constructed, ergo, the slats.
Is anyone rebating radiant barrier painting? If not, they are mullets.
Even though you didn't paint my residence, you did paint my rentals, and may certainly add my name and 'phone number to your list of highly satisfied customers. The tenant at 1107 ------------- said that her Austin Energy bill was reduced by about $75/month.

Developed by the Air Force to disguise aircraft to heat seeking radar, our radiant barrier coating has one of the highest emissivity ratings of any liquid product on the market today of .22, or a reflectivity of .78.
There are roughly 40 to 50 so-called radiant barrier products on the market today. However, only 5 products are approved from the DOE and Oakridge Labratories to meet the reflectivity value that exceeds .75. It is very important to note that the attic area must be well ventilated to maximize the performance of a radiant barrier coating. Attics that are not well ventilated will diminish the performance of a radinat barrier coating to virtually nothing.
It is important to note that coverage is critical. The manufactures say that you can expect 350 to 400 square feet of coverage per gallon and that it can go on lightly. THAT IS HOGWASH.....we average 210 square feet per gallon and it must be put it on THICK to achieve maximum performance. We have inspected many attics where the coverage has been downright disgraceful! These are attics that are not inspected by a third-party (Austin Energy, etc...) and we have seen many attics lacking as much as 50% coverage......just an awful practice and not a way to conduct business. Remember, if your garage is attached to the attic area.....this must be insulated as well. Also, be sure that the coverage extends down into the eaves and account for the surface are of any gable ends and the pitch of the roof to determine square footage.
Some features of radiant barrier include:
- Low emmissivity, high reflectivity.
- Permeable, does not trap moisture.
- Improves comfort levels.
- Improves efficiency of existing insulation.
- Only economical way to retrofit existing structures.
- Increases the value of your home or business.
