International Barrier Technology Passes Certification Hurdle to Launch Significant Market Opportunity in Mobile Offices/Modular Buildings

Fire Resistant Building Materials Company Passes Critical Fire and Wind Tests to Meet Strict Building Code Requirements for a Commercial Roof Deck System on Mobile/Modular Structures

Watkins, MN; Vancouver, BC (PRWEB) June 19, 2003 - International Barrier Technology Inc. (Barrier") (IBTGF: OTCBB; IBH: TSXV), a provider of environmentally friendly, fire resistant building materials, has successfully completed rigorous fire and wind tests that will enable the company and its partner in the endeavor, Mule-Hide Products Co., Inc., to have a Class C rated commercial roof deck assembly labeled and listed by Underwriters Laboratories Inc. (UL). The UL certification will enhance the sales launch of Barriers products into a new market: factory-built mobile offices and modular buildings for commercial use.

Building code standards and their enforcement are becoming increasingly stringent, and modular building manufacturers are demanding improved solutions to meet these requirements. Barrier and Mule-Hide formed a joint initiative to design and introduce new rated" roof deck assemblies that would provide superior fire and wind ratings compared to existing materials. While the majority of mobile commercial buildings are required to have a Class C fire rating, most are built to the more stringent Class A standard, since an effective, cost efficient Class C system has to date not been introduced.

On June 9 and 10, 2003, Barrier and Mule-Hide completed the Class C test requirements for ASTM E-108, Standard Test Methods for Fire Tests of Roof Coverings and UL 1897, ULs proprietary Wind Uplift Test for Roof Covering Systems. Using Barriers Blazeguard® fire rated wood panel, the system surpassed 240 psf wind uplift rates and will enable building users to locate these modular buildings in most coastal regions where wind is a structural design issue. Barrier anticipates the listing and labeling process to be completed within months. Sales efforts will begin immediately.

There is a great need for a Class C rated roof system in the mobile/modular market. The Blazeguard-based system fits this need to a T"," said Walt Griffin, Modular Program Manager for Mule-Hide. I am looking forward to a great relationship with Barrier as we introduce the new Blazeguard/Mule-Hide roof deck system to the industry."

The commercial mobile/modular building industry manufactured 67.5 million square feet of new structures in 2001. This is a market with the potential to significantly expand Barriers sales," noted Dr. Michael Huddy, Barriers President. These buildings are used for construction sites, education, healthcare and many other commercial uses, and this market opportunity complements Barriers growing success in multi-family residential dwelling construction."
