CAFCO® 300 HS
ISOLATEK® Type 300 HS

Quick Resources

CAFCO 300 HS / ISOLATEK Type 300 HS offers architects the option of specifying a Commercial Density product to meet the current IBC® SFRM minimum bond strength requirement of 430 psf for building heights ranging from 75′ to 420′.

CAFCO 300 HS / ISOLATEK Type 300 HS is a gypsum-based, Wet Mix Spray-Applied Fire Resistive Material specifically designed to provide high bond strength along with exceptional cost-effective thermal performance.

In addition to providing industry leading thermal and physical performance advantages, CAFCO 300 HS / ISOLATEK Type 300 also acts as a thermal insulator and is particularly effective reducing heat loss when applied to the underside of a roof deck. The added R-value can contribute to a reduction in roof insulation.

Benefits
  • Meets or exceeds all major fire protection specifications for Commercial structures including ANSI/ UL 263, ASTM E119, CAN/ULC-S101.
  • Provides up to 4 hour fire resistance ratings.
  • Meets Section 403.2.4 of the IBC High Rise Building requirement for minimum bond strength.
  • Offers the highest bond strength in the commercial density category.
  • Offers cost effective fire resistance performance.
  • Exceeds industry in-place physical performance standards.
  • Offers LEED building credits for recycled content.
  • Its additional family of products (CAFCO 300 ES / ISOLATEK Type 300 ES and CAFCO 300 SB / ISOLATEK Type 300 SB) provides specific benefits such as eliminating the need for daily priming and flushing out of lines, increased physical properties, and easily identified tint for retrofit applications.
Product Uses

Designed to provide fire protection for up to 4 hour ratings for 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 300 HS / ISOLATEK Type 300 HS 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 HS / ISOLATEK Type 300 HSis 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.
