CAFCO® 400 AC
ISOLATEK® Type 400 AC

Quick Resources

CAFCO 400 AC / ISOLATEK Type 400 AC is a gypsum based medium density Wet Mix Spray-Applied Fire Resistive Material (SFRM) designed to provide protection for structural steel in commercial and high rise construction areas which may be subjected to higher levels of abuse such as mechanical and electrical rooms or elevator shafts.

CAFCO 400 AC / ISOLATEK Type 400 AC offers enhanced strength, durability and excellent fire protection and meets the current IBC bond strength requirement of ≥ 430 psf for buildings over 75 ft. in height and 1000 psf for buildings over 420 ft. in height.

CAFCO 400 AC’s / ISOLATEK Type 400 AC’s physical properties, combined with superior fire resistive performance and application efficiencies, make it the ideal choice for high rise structures and interior conditioned environments.

Benefits
  • Offers the most cost effective fire resistance performance per unit thickness and greatest productivity of any medium density SFRM.
  • Less material is needed to achieve required fire ratings.
  • Provides added value as a thermal insulator.
  • Meets current IBC bond strength requirements for building over 420 ft. in height.
  • Meets or exceeds all major fire protection specifications for commercial structures including ANSI/UL 263 and ASTM E119.
  • Offers LEED building credits for recycled content.
Product Uses

Designed to provide fire protection for up to 4 hour ratings to various floor and roof deck assemblies, steel beams, columns, 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, CAFCO 400 AC / ISOLATEK Type 400 AC 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 400 AC / ISOLATEK Type 400 AC is classified by Underwriters Laboratories for up to 4 hours protection in accordance with ANSI/ UL263 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 400 AC / ISOLATEK Type 400 AC. The result of the evaluation process assures that the CAFCO 400 AC / ISOLATEK Type 400 AC is in compliance with the International Building Code (IBC).
