CAFCO BLAZE-SHIELD II / ISOLATEK Type II is the industry-leading commercial density Dry Mix Spray-Applied Fire Resistive Material (SFRM).
It is an inorganic, environmentally friendly, Portland cement- based formulation that provides superior fire resistance for structural steel and concrete in commercial construction environments.
This is the product of choice particularly when exposure to severe weather conditions during the construction phase is necessary, or when application efficiency, along with excellent thermal and acoustical insulation properties are desired. With all of these added benefits, it’s wise to follow the advice of many of our customers, “Don’t just fire proof it, BLAZE-SHIELD it.”
CAFCO BLAZE-SHIELD II / ISOLATEK Type II is the only commercial density product that is classified as “investigated for exterior use” by Underwriters Laboratories, thus allowing it to remain exposed to extreme weather conditions during the construction process.
- Part of the most widely specified Dry Mix Spray family throughout the world for over forty years.
- Meets or exceeds all major fire protection specifications for Commercial structures including ANSI/ UL 263, ASTM E119, and CAN/ ULC-S101.
Provides up to 4 hour fire resistance ratings.
- Exceptionally high recycled content (67% pre-consumer) and other environmentally friendly characteristics provide significant LEED credits.
- Inorganic material formulation does not promote mold or fungal growth.
- Portland cement-based formulation makes it suitable to remain exposed to a variety of extreme weather environments during construction, providing exceptional flexibility to sequencing and scheduling of projects.
- Low pressure, pneumatic spray application equipment requires less manpower to operate.
- High thermal and acoustical properties provide thermal insulation and noise abatement capabilities.
Applied directly to decking, steel beams, columns or concrete surfaces for concealed commercial environments which may be exposed for prolonged periods of time during the construction cycle.
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 BLAZE-SHIELD II / ISOLATEK Type II 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 1000°F (537°C) after 5 minutes and gradually reaches a temperature of 2000°F (1093°C) after a period of up to 4 hours.
CAFCO BLAZE-SHIELD II / ISOLATEK Type II 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.
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.
An MEA Number is the number assigned to a product that has been approved for use in New York City by the MEA Division. CAFCO BLAZE-SHIELD II / ISOLATEK Type II has been reviewed and MEA numbers have been assigned.
The MEA division regulates “certain materials and equipment (that) require Department of Buildings acceptance.” These manufactured items affect public safety, health and welfare (including structural stability and fire safety) and are usually a permanent part of a building.
Underwriters Laboratories (UL) has conducted a technical evaluation on CAFCO BLAZE-SHIELD II / ISOLATEK Type II. The result of the evaluation process assures that the CAFCO BLAZE-SHIELD II / ISOLATEK Type II is in compliance with the International Building Code (IBC).
