HeatBloc: Keep Your Home In The Shade

Until now the only types of radiant barriers available were foil film, metalized plastic film, and metalized "chips" . These types of barriers are installed by attaching to the underside of the roof with staples or sprinkled about on top of the fiberglass insulation on the attic floor. 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!


Hy-Tech Barrier Coat is the ONLY radiant barrier paint that contains pure metal (aluminum) pigment, Hy-Tech insulating ceramic microspheres and NO mineral spirits or other volatile, flammable solvents.




Very low odor, soap and water clean up.

Low applied cost per square foot

Dual protection: The metallic aluminum pigment reflects away radiant energy or heat from the sun during the summer months and in winter the same microscopic aluminum particles prevent radiant heat from leaving the building. Hy-Tech insulating ceramics further reduce conductive heat transfer.

Permeable, does not trap moisture but reduces its rate of transfer.

Easily installed using brush, roller, or spray

Excellent for back priming wood sheathing and siding in new construction, not only providing a superior radiant barrier, but also protects against wood rot from water intrusion through cracks and splits in the wood

Saves money by lowering heating and cooling cost of operation and wear and tear of the equipment.

Improves efficiency of existing insulation by lowering the temperatures that it is exposed to.

An Easy way to upgrade existing structures

Easily applied to Attic Space,underside of roof decking, side walls and overhead doors in metal buildings, Duct work, Pipes, interiors of cargo transportation vehicles, barns, storage buildings, animal shelters, grain silos, poultry housing...the applications are endless

Due to the high reflectivity of the coating, Barrier Coat increases interior lighting levels in commercial and industrial buildings which aids in reducing lighting costs.

In buildings heated by infrared heaters, wood burning stoves or other radiant heat sources, Barrier Coat greatly improves the efficiency of the heat source, reducing fuel and energy costs

On interior wall applications Barrier Coat not only provides a barrier to radiated heat but also an Aluminum vapor barrier which reduces water vapor transfer through the walls, a real plus for older homes and homes with EIFS wall systems.

Barrier coat can be top coated with a decorative conventional wall paint.

Environmentally Friendly! Contains No ammonia, No alcohol, No solvents!

SAVE Money...Do it yourself. We include with every order, step by step instructions on how you can easily and inexpensively apply barrier coat.

Spread Rate: 200 sq ft per gallon (for attic spray applications) 300 sq ft per gallon for semi smooth walls and ceilings.

Two coats are recommended on new unprimed wood.

to insure an even distribution of the aluminum and ceramic particles.

Available in 1 Gal and 5 Gal containers
