ISOLATEK® Type 3000 ES is a gypsum based, Wet Mix Spray-Applied Fire Resistive Material that is designed to allow the material to remain in the hose up to 72 hours (such as overnight or over the weekend) without the need to purge with water. This improves job site productivity by reducing both wash-out and start up times when used in conjunction with ISOLATEK Type 3000.

ISOLATEK Type 3000 ES’s physical properties, combined with superior fire resistive performance and application efficiencies, make it the ideal choice for high rise structures with time sensitive deadlines.



  • ISOLATEK Type 3000 ES provides all of the benefits of ISOLATEK Type 3000, along with the elimination of washout and reduced start up times, thus increasing productivity.
  • 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 ISOLATEK Type 3000 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, ISOLATEK ®Type 3000 ES has undergone the most rigorous testing in accordance with the world’s most demanding safety protocols.

UL 263, ASTM E119 - UL-263

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 3000 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.

Evaluation Service Report

Underwriters Laboratories (UL) has conducted a technical evaluation on ISOLATEK Type 3000 ES. The result of the evaluation process assures that the ISOLATEK Type 3000 ES is in compliance with the International Building Code (IBC).
