low-e attic and decking radiant barrier

U.S. PATENT PENDING

Product Description

Radiance^™ Low-E Attic and Decking Radiant Barrier is designed to be applied to the underside of roof decks.  It helps keep structures warmer in the winter, and cooler in the summer, while at the same time reducing heating and cooling costs.

The physics behind Radiance is similar to low-e glass windows, which reduce the loss of radiant heat in the winter and the emission of heat into a building in the summer.  The "e" in low-e refers to emissivity, which is the ability of a surface to emite or absorb radiative energy.  The lower the "e" value the more efficient it is in managing energy and the greater the energy savings.

Radiance Low-E Attic and Decking Radiant Barrier is applied like a normal paint onto plywood decks, or properly  prepared metal or masonry surfaces.  It's a smart coating which slows the heat loss of a building in the winter and slows heat gains in the summer.  Radiance has microscopic reflective particles suspended in a infrared transparent binder matrix.  In the winter more than 50% of the radiant heat which would normally escape is reflected back, slowing the loss of heat from the building.   In the summer, it keeps more than 50% of the sun's infrared energy from emitting into the building, keeping the building and its occupants cooler and more comfortable.

HOW TO APPLY RADIANCE™

Surface preparation

Aluminum and Galvanized Steel: Remove all surface contaminants by washing with an appropriate cleaner.  Any corrosion must be removed with hand tool cleaning, steel wool or other abrading method.

Drywall: Remove all surface contaminants by washing with an appropriate cleaner.  Fill cracks and nail holes with patching paste/spackle and sand smooth.  Joint compounds must be cured and sanded smooth.  Remove all sanding dust.  Water stains may be sealed with a commercial stain killer.

Masonry, concrete, cement brick and block: Remove all surface contaminants with an appropriate cleaner.  All surfaces must be fully cured.  Remove all form release and curing agents.  Rough surfaces can be filled to provide a smooth surface.

Plaster: Base plaster must be cured and hard.  Textured, soft, porous, or powdery plaster should be treated with a solution of 1 pint household vinegar to 1 gallon of water. Repeat until the surface is hard, rinse with clean water and allow to dry.

Steel: Remove all surface contaminants by washing with an appropriate cleaner. Rust and mill scale must be removed using sandpaper, steel wool, or other abrading methods. Bare steel must be primed the same day as cleaned.

Wood: Remove all surface contaminants by washing with an appropriate cleaner. Sand any exposed wood to a fresh wood surface.  Patch any nail holes and imperfections with a wood filler or putty and sand smooth.

Previously painted surfaces: Remove all loose coatings and corrosion by scraping, sanding or other abrading method.  Dull glossy and non-porous surfaces with sandpaper or abrasive cleaner.  Remove all surface contaminants by washing with an appropriate cleaner.  Patch and fill areas as needed.  Spot prime any bare areas with the appropriate primer.

Mildew: Mildew must be removed before painting by washing with a solution of 1 quart household bleach and 3 quarts warm water. Wear rubber gloves and protective clothing.  Apply the solution and scrub the mildewed area.  Allow the solution to remain on the surface for 10 minutes.  Rinse thoroughly with clean water and allow the surface to dry 48 hours before painting.  DO NOT ADD DETERGENTS OR AMMONIA TO BLEACH SOLUTION.

Mixing

Stir thoroughly before each use.

Application

Radiance Low-E Attic and Decking Radiant Barrier may be applied by brush, roller, or sprayer. The preferred method may be spraying because of protruding roofing nails.

Roller: Use a 3/16" or 3/8" synthetic-nap roller cover.

Airless sprayer: Recommended pressure is 2,000 psi using tip size 0.018" to 0.021".

Dry Time

Dries to the touch in 2 - 4 hours at 77°F and 50% relative humidity.  Only one coat is required, but allow 8 hours between coats.

Clean up

Use warm, soap water.  Follow sprayer manufacturer recommendations when cleaning equipment.
