In the last century, the only cost-effective insulation for the home was mass insulation like fiberglass, cellulose and foam that reduced heat transfer by convection and conduction. The “R-value” was the measure of how good a job those insulators did. Yet R-value measures only the smallest part of residential heat transfer. E-value is the measure of emissivity, radiant heat transfer, the principle source of energy loss. New technologies make it practical to achieve extremely low emissivity in window glass and in a reflective film ideal for the attic. As these low-E technologies advance, the codes will catch up and E-value will replace R-value as the primary measure of energy efficiency.

BHHI Attic Radiant Barriers is designed to allow vapor to escape the housing envelope with Perm Rating of 13 – it will not contribute to mildew growth in your home.

BHHI Attic Radiant Barriers Multilayer Attic Energy Barrier is fire-resistant with a Class A fire rating – it’s less combustible than the structure to which it attaches. Of course, like almost any material, it will melt and eventually burn if exposed to an open flame.

BHHI Attic Energy Barrier is Department of Energy approved and bears the Energystar® mark. This is the gold standard in energy efficiency and qualifies for most federal, state and energy company rebates. Check with your BHHI Attic Radiant Barriers rep to learn what’s available in your

The so called “ceramic” coatings actually are ordinary coatings that have had small ceramic spheres added. The premise sounds good, except that the science does not support the claims that are made. Even though these coatings may be applied heavier than ordinary paint, there simply is not enough thickness to effect insulation of any measure. These ceramic coatings have been debunked by the Department of Energy and the Federal Trade Commission and they do not increase reflectivity.

1. Recoating should begin with a clean, sound surface.

2. If recoating with the same color, COOLWALL® finish may be applied without a primer.

3. If recoating in a different color, you may require both COOLWALL® primer and finish.

Currently refers to interior paints only. A product such as COOLWALL® SYSTEM meets the Green Seal requirements.

A color difference of 1 DELTA (Δ) value is the point where a color difference begins to be perceptible to the average person’s eye. A difference of 3 DELTA (Δ) values is a difference noticeable by most people.

COOLWALL® should have negligible effect to an existing film as it relates to stress. The existing paint should be clean and sound with proper adhesion to the substrate. COOLWALL®, will be the same regardless of whether it is applied to an existing paint or coating film or a substrate that has never been painted or coated before.

The ability of COOLWALL® to keep wall surfaces cooler is based on its ability to reflect a much greater percentage of the non-visible portion of the spectrum leaving the color relatively unaffected.
COOLWALL® has tremendous performance to reflect these elements. The ability of COOLWALL® to keep wall surfaces cooler is based on its ability to reflect a much greater percentage of the non-visible portion of the spectrum relatively unaffected.

COOLWALL® will provide the designer the opportunity to select a much wider range of colors in medium and deep tones without the concern of fading.

COOLWALL® does not work by an “insulation” process and thus it does not have an “R value” (R stands for resistance). Instead, COOLWALL® reflects the infrared energy from the sun so that the wall does not get as hot in the first place. This substantially reduces the amount of heat that the fiberglass or other type of insulation needs to keep out. By increasing Solar Reflectivity in the entire color spectrum, COOLWALL® is reducing surface temperatures and cooling costs.

COOLWALL® has been tested by the U.S. Department of Energy’s Oak Ridge National Laboratory to reduce cooling costs by up to 21.9%* (percentage savings are based on DOE study which showed savings ranging from 4.2 – *21.9%).
*Percentage of cooling costs and surface temperature reductions will vary based on color chosen, geographical location, climate conditions, and substrate type. In some climates there may be a heating penalty.
