Thermal Barrier- Ure-K is a thermal barrier approved as a building interior insulation to delay the ignition and reduce the surface burning rate of low melting, combustible rigid spray-on polyurethane foam. Ure-k may be sprayed over foam in existing buildings or it can be used as a protective coating over foam in new construction projects as a combination system. Thermal Insulation- Ure-k applied over polyurethane provides additional thermal resistance which will meet the stringent "R" values required for today's energy conservation needs. The combination of Ure-K and polyurethane has the highest efficiency of all available insulations. Noise Control- Ure-K is a monolithic coating which will provide a highly efficient sound absorbtion surface in either new or existing buildings. This is an imortant benefit in controlling noise levels to meet OSHA and other requirements. Installation- The Ure-K fibers and liquid binder are applied to the surfaces simultaneously in separate streams through equipment especially engineered to control the material density and adhesive/fiber mixture. The Ure-K binder provides excellent adhesion to all types of polyurethane foam insulations. Thermal Barrier Testing- Ure-K was tested and has been accepted by
National Code Bodies and Fire Insurance Companies as a thermal barrier
coating over polyurethane foam, used as an interior insulating
product. The following tests satisfied these requirements. |
Full Scale Corner Test- Test Method: A full scale corner test
was conducted in accordance with Factory Mutual Building Corner Fire
Test Procedure with the test surface applied to the interior of the
simulated building structure. The structure was 25 feet high
consisting of a corner wall configuration and a roof or ceiling
membrane. One wall was 50 feet and the other 28 feet long.
The test surface was applied to both the walls and ceiling. Ure-K
was applied 3/4 " thick over 1 1/2 " polyurethane with a flame
spread rating of over 200 in the ASTM-E-84 Tunnel Test procedure.
No sprinklers were used in the test. ASTM-E-119 Test Method: The test panel consisted of a urethane foam over which Ure-K was applied. The urethane foam had a flame spread rating of less than 75, per the manufacturer, and was applied to a 1/2" sheetrock to a thickness of approximately 3". Ure-K was spray applied over the foam to a nominal thickness of 1 inch. Test Conclusion: The finished rating is the shorter time span for a 250 degree F average of the five thermocouples, or a 375 degree F maximum temperature rise of one thermocouple above ambient on the unexposed face of the thermal barrier. Based upon the above criteria, Ure-K as tested had a finished rating of 25 minutes and 1 second.

Enclosed Room Test-
Test Method: The test facility consisted of a fully enclosed 8 x 12 x 8 foot room. The urethane foam, with a flame spread rating of less than 75, was spray applied to the interior of the room. A 1" application of Ure-K covered the urethane. The wood crib fuel source was constructed of 1.5" x 1.5" sticks of Douglas Fir wood in 15" lengths. The crib had a weight of 30 lbs. Temperatures in the room reached a high of 2,013 degrees F. The length of the test was 30 minutes. Test Results: Under these specified test conditions, the Ure-K material did substantially remain in place. The Ure-K did crack open and recede due to charring in several areas, most notably in the crib corner area. ASTM-E-84-79a Test Method: To evaluate performance of the Ure-K in relation to that of asbestos cement board and red oak flooring under similar fire exposure. The results are expressed in terms of flame spread, fuel contribution and smoke development during a 10 minute exposure and are recorded as a ratio with asbestos cement board- 0 and red oak flooring- 100. Test Results: Flame Spread = 10;
Fuel Contribution = 40; Smoke Development = 0 |
