Dallas Professional Spray On Radiant Barrier Contractor

Spray On Radiant Barrier

is actually considered a Interior Radiation Control Coating or IRCC. Spray radiant barrier is not actually a radiant barrier but more of a radiant coating. Spray radiant barrier is a paint mixed with metal flecking that provides the reflective property required to reflect the heat away from your attic and is sprayed onto the underside of the roof deck. The products goal is to reduce the loss of heat in the winter through the roof but most of all keeps heat out of your attic in the summer.

Perkins Inc. installs Henry LiquidFoil™ Attic Barrier. Henry LiquidFoil™ Attic Barrier is a radiant heat control coating that keeps heat out of a building during the summer and in during the winter. By keeping up to 84% of radiant heat from entering or escaping a building, LiquidFoil™ Attic Barrier can cut energy consumption and costs significantly. And it's as easy to apply as paint and dries quickly to a shiny, metallic finish.

All materials give off, or emit, energy by thermal radiation as a result of their temperature. The amount of energy emitted depends on the surface temperature and a property called the "emissivity" (also called the "emittance"). The emissivity is a number between zero (0) and one (1). The higher the emissivity, the greater the emitted radiation.

Building products, such as wood, brick, painted surfaces and plasterboard exhibit high emissivities (0.7-0.95). When heated above the temperature of adjacent surfaces, they radiate most of their heat energy to cooler surfaces. A good spray radiant barrier works by lowering the roof deck and roof rafters surface emittance to 0.24 or lower, lessening their ability to hold and radiate heat as well as reducing the amount of radiation incident on the insulation. Since the amount of radiation striking the top of the insulation is less than it would have been without a radiant spay, the insulation surface temperature is lower and the heat flow through the insulation is reduced.

Radiant barriers do not "absorb" heat like mass insulation (fiberglass, cellulose, foam, etc). Instead, radiant barriers with their highly reflective surfaces reflect 95% of the radiant heat that hit their surfaces and therefore have no R-value rating.

Installing a Henry LiquidFoil spray radiant barrier between the heat source (sun) and an existing R-value rated insulation will improve the effectiveness of the R-value rated insulation. Why? Because only 16% of the radiant heat is now hitting the R-value rated mass insulation thereby extending the amount of time it has to absorb heat before becoming saturated and passing the heat into your living spaces.
