Quick Resources

CAFCO 300 ES / ISOLATEK Type 300 ES is a commercial density, Wet Mix Spray-Applied Fire Resistive Material (SFRM) that is virtually identical to CAFCO 300 / ISOLATEK Type 300, specifically designed to provide delayed set times in order to allow slurry to remain in the hose for up to 72 hours. This provides the means to applicators to reduce both wash-out and startup times when used as a system in conjunction with CAFCO 300 / ISOLATEK Type 300, CAFCO 300 SB / ISOLATEK Type 300 SB and ISOLATEK QWIK-SET.

  • CAFCO 300 ES / ISOLATEK Type 300 ES provides all of the benefits of CAFCO 300 / ISOLATEK Type 300, along with the elimination of washout and reduced start up times, which increases productivity at both ends of the day.
  • Exceeds industry in-place physical performance standards.
  • Offers LEED building credits for recycled content.
  • Its light red color provides an easily identifiable marker to clearly indicate its use.
Product Uses

Designed for use in conjunction with CAFCO 300 / ISOLATEK Type 300, CAFCO 300 SB / ISOLATEK Type 300 SB and ISOLATEK QWIK-SET to provide delayed set time, thereby allowing slurry to remain in the hose for up to 72 hours.

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 300 ES / ISOLATEK Type 300 ES 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 up to 4 hours.

CAFCO 300 ES / ISOLATEK Type 300 ES 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.

New York City Materials and Equipment Acceptance (MEA)

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 300 ES / ISOLATEK Type 300 ES 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.

Evaluation Service Report

Underwriters Laboratories (UL) has conducted a technical evaluation on CAFCO 300 ES / ISOLATEK Type 300 ES. The result of the evaluation process assures that the CAFCO 300 ES is in compliance with the International Building Code (IBC).
