CAFCO SprayFilm WB 7 / ISOLATEK Type WB 7 Intumescent Fire Resistive Material (IFRM) is a new water-based, intumescent coating designed for the fire protection of interior structural steel.
CAFCO SprayFilm WB 7 / ISOLATEK Type WB 7 introduces new levels of coverage and competitive thickness requirements in the industry. The technological improvements introduced by Type WB 7 also allows for easier application and a more environmentally friendly product.
CAFCO SprayFilm WB 7 / ISOLATEK Type WB 7 provides architects the ability to design using steel that can be decorative and aesthetically pleasing. It can be top coated to match its surroundings and allows steel to be left exposed to view while providing the required fire resistance rating.
- Water-Based Intumescent coating with zero VOC’s.
- Provides up to 2-hour fire resistance ratings in accordance with BS476: Parts 20 & 21 compliant assessment per Warrington Fire.
- Contains no solvents or harmful compounds.
- Superior performance proven by wide range of testing.
- Durable, smooth architectural finish.
- Quick, easy application and clean up.
- Can be finished with a wide variety of topcoat types and colours.
Wherever an aesthetically pleasing extremely durable finish is desired on exposed steel beams and columns utilized in a variety of open space locations including corporate headquarters, convention halls, atriums, retail facilities, hospitals, airports, rail and bus depots.
Fire Tests & Approvals
In order to meet the performance and durability criteria set forth by the American Institute of Architects (AIA) and other major industry specifying organizations, CAFCO SprayFilm WB 7 / ISOLATEK® Type WB 7 has undergone the most rigorous testing in accordance with the world’s most demanding safety protocols.
This cellulosic fire test is traditionally used to evaluate materials for use in the protection of modern day commercial structures. This test reaches 576°C (1069°F) after 5 minutes and gradually reaches a temperature of 1153°C (2107°F) after a period of up to 2 hours.
CAFCO SprayFilm WB 7 / ISOLATEK Type WB 7 has been evaluated in accordance with BS476: Parts 20-21: 1987 for periods up to 2 hours on beams and columns which is listed within a UL assessment report.
The UL Classification Mark indicates compliance with global requirements as it relates to a specific risk or casualty. With the Classification service, UL determines that a manufacturer has demonstrated the ability to produce a product complying with UL’s requirements with respect to one or more of the following:
- Specific risk, e.g., casualty, fire, etc.
- Performance under specific conditions
- Compliance with regulatory codes
- Compliance with specific standards such as international standards
- Other condition, as determined by UL
All of the products carrying a UL Classification Mark are covered by UL’s Follow-Up Services program to verify that products carrying the UL Classification Mark continue to be manufactured in compliance with UL’s safety requirements.
CAFCO SprayFilm WB 7 / ISOLATEK Type WB 7 has been assessed for jurisdictions in Asia, Oceania and Latin America.
