CAFCO SprayFilm WB 5 / ISOLATEK Type WB 5 Intumescent Fire Resistive Material (IFRM)
CAFCO SprayFilm WB 5 / ISOLATEK Type WB 5 is a technological breakthrough in water-based intumescent technology which opens the door to exposed interior structural steel design once considered unaffordable.
Breakthroughs in Thermal Performance make SprayFilm WB 5 / Type WB 5 the most technologically advanced, intumescent coating on the market. It achieves required fire resistive ratings using less material than other intumescent coatings—often times far less material depending on conditions.
SprayFilm WB 5 / Type WB 5 also enhances productivity on the job site. SprayFilm WB 5 / Type WB 5 allows for greater wet-film thickness through increased hangability, meaning it can be applied in fewer coats; it also allows for more coats per day, meaning the entire job can be finished in less time.
SprayFilm WB 5′s / Type WB 5’s thickness advantages result in an aesthetically pleasing, durable surface. Its unprecedented Zero Volatile Organic Content (VOC) formulation provides significant environmental advantages and is a contributing factor towards achieving Leadership in Energy and Environmental Design (LEED) credits. Our continued dedication to developing environmentally friendly products is further exemplified by the fact that since SprayFilm WB 5 / Type WB 5 requires less material, there is less waste, as well as less energy required to produce, ship and install it.
Benefits
- Significantly reduced Dry Film Thicknesses (DFTs) provide the most cost effective IFRM protection in the industry.
- Has Zero VOC’s and requires less energy to produce, ship and install, which both contribute to LEED certification.
- Durable, smooth architectural finish combines aesthetics with long lasting performance.
- Low Odor and contains no solvents or harmful compounds.
- Environmentally friendly application and clean up.
- Can be finished with a wide variety of topcoat finishes and colors to blend with other design elements.
- Provides up to 3-hour fire resistance ratings in accordance with ANSI/ UL 263, ASTM E119 and CAN /ULC-S101.
Product Uses
Wherever an aesthetically pleasing extremely durable finish is desired on exposed steel beams, and columns utilized in a variety of interior 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 5 / ISOLATEK Type WB 5 has undergone the most rigorous testing in accordance with the world’s most demanding safety protocols.
Cellulosic – ANSI/UL263 (ASTM E119) – Fire Tests of Building Construction and Materials
This cellulosic fire test is traditionally used to evaluate materials for use in the protection of modern day commercial structures. This test reaches 1000°F (537°C) after 5 minutes and gradually reaches a temperature of 2000°F (1093°C) after a period of 4 hours.
CAFCO SprayFilm WB 5 / ISOLATEK Type WB 5 is classified by Underwriters Laboratories for up to 3 hours protection on columns and 2 hours on beams in accordance with the cellulosic fire test and is listed within various UL Designs.
UL Classification Mark
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.
Evaluation Service Report
Underwriters Laboratories (UL) has conducted a technical evaluation on CAFCO SprayFilm WB 5 / ISOLATEK Type WB 5. The result of the evaluation process assures that the CAFCO SprayFilm WB 5 / ISOLATEK Type WB 5 is in compliance with the International Building Code (IBC).
