Testing Information
RIMA, the Reflective Insulation Manufacturers Association, performed testing of the most widely used IRCCS, Interior Radiation Control Coating Systems, otherwise known as attic radiant barrier coatings. The test results show that HeatBloc Ultra is the most effective coating on the market. Click to see pdf report.
Effects on Roof Shingles
A regular concern with the use of radiant barriers that are applied to the roof decking is: Does it have a negative effect on the life or warranty of the shingles? Again, RIMA has produced a report explaining that there is no detrimental effect to roof shingles and that it should not invalidate a shingle warranty. However, you should check your warranty and contact the manufacturer to verify their particular warranty requirements. Click here to read pdf report.

|
HEATBLOC Ultra radiant attic barrier is formulated to be sprayed on the underside of the roof deck, ridge and gable ends. Applying a thin even coat to these surfaces creates an effective radiant barrier that will stop 75% of the potential radiant energy transfer into the attic. |
|
Features and Benefits |
| • |
Low emissivity with 0.25 "e" value - Reduces heating and cooling bills |
| • |
Reflects up to 75% of radiant energy - Increases interior comfort level |
| • |
100% seamless coverage of attic space - More cost efficient than alternative attic systems |
| • |
Will not disrupt attic mounted antenna or cell phone reception |
| • |
Breathable - Will not increase attic moisture |
| • |
One coat coverage on bare wood and primed metal - Fast application |
| • |
Application by spray, roller and brush - Easy to apply |
|
For Best Performance
Do not topcoat, must remain in contact with air.
Do not tint.
HEATBLOC Ultra is not designed to withstand any handling.
Use shielded safety lighting.
Be sure to follow proper ventilation instructions.
To maximize the effectiveness of HEATBLOC Ultra, a minimum of 1" of airspace is require between the HEATBLOC Ultra and the next substrate.
Ensure appropriate personal protective equipment is used. Review Material Safety Data Sheet for further information.
Compliances
ASTM C 1321 |
Preparation
There is no need to prime most surfaces before applying HEATBLOC Ultra. All surfaces should be clean, dust-free, and dry.
Bare metal surfaces must be primed with the appropriate primer. It is usually recommended to prime the same day it is cleaned. 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.
Concrete must be fully cured. Remove all form release and curing agents. Rough surfaces can be filled to provide a smooth surface.
Mildew must be removed before painting by washing with a solution of 1 quart household bleach and 3 quarts warm water. Wear appropriate personal protective equipment. 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. |
Application
HEATBLOC Ultra is designed for interior use only. Apply to the bottom side of roof decking (OSB, plywood, chip board, sheetrock, concrete or masonry), to primed or coated metal roofing, or to rafters and joists directly attached to roof.
Provide mechanical ventilation from a) home interior-to-attic-to-outside and b) outside-to-attic-to-outside. Run ventilation 10 minutes prior to use, during use and for at least 30 minutes after application.
Remove lid from Part B and use a spatula to put entire contents into the 5-gallon pail containing Part A. Mix thoroughly for 3 minutes with a squirrel cage type mixer before use. Make certain to only mix as much material as can be applied in one day.
HEATBLOC Ultra may be applied by brush, roller, or sprayer. The preferred method is spraying. If using an airless sprayer, recommended pressure is 2,000 psi using tip size of 0.019" to 0.021". For best results use a spray pump size 3/4 GPM or greater. A 3/8" synthetic-nap roller can also be used.
The average coverage rate of HEATBLOC Ultra is 325 - 425 sq. ft/gallon depending on texture and porosity of the substrate.
Dries to the touch in 2 - 4 hours at 77°F (C) and 50% relative humidity. |
Clean Up
Use warm, soapy water. Follow sprayer manufacturer recommendations when cleaning equipment. |

Precautions
Part A: Avoid contact with skin, eyes and clothing. Wash thoroughly after handling. Keep container closed when not in use. DO NOT take internally. Use only with adequate ventilation. Use impervious gloves, eye protection and if the TLV is exceeded or used in a poorly ventilated area, use NIOSH/MSHA approved respiratory protection in accordance with applicable Federal, state and local regulations.
Part B: KEEP AWAY FROM HEAT, FLAME AND SOURCES OF IGNITION. Vapors are heavier than air. Keep container closed. Use only with adequate ventilation. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling. Avoid breathing vapors. DO NOT take internally. Use impervious gloves, eye protection and if the TLV is exceeded or used in a poorly ventilated area, use NIOSH/MSHA approved respiratory protection in accordance with applicable Federal, state and local regulations. |
First Aid
