ISOLATEK Type M-II
ISOLATEK® Type M-II is the industry’s leading High-density Wet Mix Spray-Applied Fire Resistive Material (SFRM) designed to provide fire protection for structural steel and concrete where physical abuse or high traffic may be anticipated.
Due to its Portland cement formulation, thermal performance and proven superior durability, and ease of application, ISOLATEK Type M-II is the preferred choice worldwide for use in the most challenging commercial and industrial applications.
Benefits
Product Uses
It is specifically developed for spray and trowel applications to protect structural columns and beams in exterior environments and interior applications where highest levels of abrasion resistance and durability are necessary.
Recommended for interior and exterior exposed application to include clean rooms, parking garages, mechanical rooms, manufacturing facilities, petrochemical plants, and other industrial uses where high density concrete type protection is required.
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 M-II 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 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 M-II 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:
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.
Cellulosic – BS476: Part 20: 1987 – Method of Determination of the fire resistance of elements construction & EN 1363-1 – Fire Resistance Tests, General Requirements:
This cellulosic fire test is traditionally used to evaluate materials for use in the protection of modern day commercial structures. This test reaches 576°C (1069°F) after 5 minutes and gradually reaches a temperature of 1153°C (2107°F) after a period of up to 4 hours.
ISOLATEK Type M-II has been evaluated in accordance with BS476: Parts 20-21: 1987 & EN 1363-2 for periods up to 4 hours on beams and columns which is listed within a Warrington assessment report.
ANSI/UL 1709, Rapid Rise Fire Test of Protection Materials for Structural Steel
This fire test is provided to evaluate materials for use in petrochemical facilities and other similar structures that may be subjected to higher levels of heat generated by hydrocarbon-based fires. Unlike cellulosic-based fires, which are evaluated in accordance with test method ANSI/UL 263, ASTM E 119, which reaches a temperature of 2000°F (1093°C) over a period of 4 hours, the ANSI/UL 1709 test method reaches 2000°F after five minutes and maintains that temperature over the duration of the test. Only materials tested and classified in accordance with UL 1709 can be used where the risk of a hydrocarbon fire exists.
ISOLATEK Type M-II and ISOLATEK Type TG are classified by Underwriters Laboratories for up to 4 hours protection in accordance with the Rapid Rise Fire Test. The specific listing within the UL Fire Resistance Directory is UL Design XR704 , UL Design XR729 , UL Design XR730
2nd ANSI/UL 1709, Rapid Rise Fire Test of Protection Materials for Structural Steel (following initial ANSI/UL 1709 Rapid Rise Fire Test)
2nd ANSI/UL 1709, Rapid Rise Fire Test of Protection Materials for Structural Steel (following initial ANSI/UL 1709 Rapid Rise Fire Test) as above however subjecting ISOLATEK Type M-II to Two Full Scale UL 1709 Fire Tests within a 24-hour period (tested, allowed to cool to ambient and re-tested).
ANSI/UL1709 Environmental Exposure Tests (Aging, High Humidity, Industrial Atmosphere, Salt Spray, Combined Wet/Freeze/Dry Cycling, Acid Spray and Solvent Spray)
In addition to the required ANSI/UL1709 Environmental Exposure Tests (Aging, High Humidity, Industrial Atmosphere, Salt Spray and Combined Wet/Freeze/Dry Cycling), ISOLATEK Type M-II has also been tested under the following conditions:
Hydrocarbon – BS 476, Parts 20-21: 1987 Appendix D – Hydrocarbon Heating Conditions
BS476 Part 21 1987 is the British Standards method for determination of the fire resistance of load bearing elements of construction including Beams, Columns, Floors, and Flat roofs. ISOLATEK Type M-II has undergone testing and meets the criteria for five limiting temperatures ranging from 350°C (662°F) to 550°C (1022°F). Thicknesses of ISOLATEK Type M-II have been determined based on the required hourly rating, the steel section’s W/D (Hp/A) ratio and the required limiting temperature.
Gas Explosion Test (3-Bar Blast Overpressure)
The above test serves to demonstrate the resistance and thermal performance of a fire resistive material subjected to a blast, either by fueled or explosive sources. Steel members protected with CAFCO FENDOLITE M-ll were subjected to a blast (having a nominal overpressure of 3 bars) in accordance with Spadeadam Site Test Procedure No. 108. The results following this extensive blast revealed little to no damage to the fire resistive material.
CAFCO FENDOLITE M-ll has been issued a Lloyd’s Register Certificate after successfully completing this test.
Factory Mutual
ISOLATEK Type M-II is a Factory Mutual (FM) approved product.
ISOLATEK Type M-II has obtained the Factory Mutual (FM) approval for use as a fire protective coating for Liquid Petroleum Gas (LPG) steel storage vessels and process structures with Hose Stream.
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. ISOLATEK Type M-II (CAFCO FENDOLITE M-II in the Americas) 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 ISOLATEK Type M-II (CAFCO FENDOLITE M-II in the Americas). The result of the evaluation process assures that the ISOLATEK Type M-II is in compliance with the International Building Code (IBC).
