As a Radiant Barrier: Stops heat from entering or escaping.
There are a few sprayable paint coatings available that are sold as radiant barriers but they all contain volatile solvents which are not only hazardous to the installer but also to the homeowner as the toxic fumes penetrate down through the ceilings and into the interior. Don’t be fooled by the terms “latex base”or “water cleanup” as they do not reflect the true chemical makeup of the coating. Read the ingredients!
Our Radiant Barrier Coat is the ONLY radiant barrier paint that contains pure metal (aluminum) pigment, insulating ceramic microspheres and NO mineral spirits or other volatile, flammable solvents.
How It Works:
Aluminum is highly reflective to infrared (IR) due to the high concentration of mobile electrons. RB Coat contains aluminum metal in the form of thin “Leafing” aluminum flakes which are highly reflective and reduce the penetration of IR radiation. The overlapping aluminum flakes align themselves parallel to and concentrated near the surface of the coating and have reflectance values of 0.75 to 0.8 for the key spectral range of 1 to 8 .mu.m.
In addition to the infrared reflective aluminum pigment, RB Coat also contains a very high concentration of heat reducing insulating ceramics. The combination of these two heat reduction pigments forms a “Ceramic Vacuum Matrix” which minimizes solar-induced heat build-up
As a Sound Barrier:
The hollow ceramic microspheres are a vacuum inside. The microscopic vacuum spheres resist thermal conductivity and reduces the transfer of sound fairly well.
As a Vapor Retarder: You Must Prevent Moisture Accumulation
Moisture control is a major concern associated with fiberglass thermal insulation. The warm air inside your house contains water vapor. If this vapor passes into the insulation and condenses, it can cause significant loss of insulating value. If moisture becomes deposited in the building structure, it can cause mold growth, peeling paint, and eventual rotting of structural wood.
Vapor retarders are special materials that reduce the passage of water vapor. Vapor retarders should be used in most parts of the country. In colder climates, place the vapor retarder on the warm side–the lived-in side–of the space to be insulated. This location prevents the moisture in the warm indoor air from reaching the insulation.
To guard against moisture problems, use RB Coat on interior walls and ceilings and provide adequate ventilation for the house. If you have a crawl space you should spray the underside with RB Coat.
