ISOLATEK® Type 304 is a low density, Wet Mix Spray-Applied Fire Resistive Material (SFRM) specifically designed to provide 4 hour fire resistance ratings on floor assemblies and supporting structural members.
- Meets or exceeds all major fire protection specifications for Commercial structures including ANSI/UL 263, ASTM E119, and CAN/ULC-S101.
- Offers LEED building credits for recycled content.
- Exceeds physical performance standards for fire protection and durability to impact.
- Excellent choice for concealed environments.
Designed to provide up to 4 hour fire protection for various floor and deck assemblies, steel beams, and joists in commercial construction projects.
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, ISOLATEK® Type 304 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 537°C (1000°F) after 5 minutes and gradually reaches a temperature of 1093°C (2000°F) after a period of up to 4 hours.
ISOLATEK Type 304 is classified by Underwriters Laboratories for up to 4 hours protection 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.
