International Barrier Technology Reports 51% Growth in Quarterly Sales Revenue and 96% Growth in Sales Volume for the Fiscal First Quarter Ended September 30, 2010

WATKINS, MN--(Marketwire - October 25, 2010) -  International Barrier Technology Inc. ("Barrier") (OTCBB: IBTGF) (TSX-V: IBH), the manufacturer of Pyrotite®, a proprietary fire-resistant building material that contains a large volume of water engineered to release at high temperatures, reports revenue and sales volume results for the first fiscal quarter ended September 30, 2010.

Overall revenue generated for the quarter was $879,274, a 51% increase over the $581,536 generated during the same period in the previous year. Revenue for the reported 2010 quarter would have shown a 69% increase if the value of the substrate panel were reflected in Barrier's sales price; as was the case in the previous year. Barrier's Supply Agreement with LP® Building Products, the world's largest producer of OSB, is a "treatment only" service where the resulting fire rated panel is both trademarked and sold by LP. Quarterly revenue into the Residential Roof Deck/Wall Assembly/Structural Insulated Panel Market increased 109% from $85,247 to $178,125, and revenue into the Commercial Modular Market increased 46% from $242,039 to $353,356.

Sales volume of shipments of Barrier products for the quarter ending September 30, 2010, was 1,774,100 sq. ft. This is an increase of 96% over the 903,000 sq. ft. that was shipped during the first quarter in the comparable fiscal year in 2009. In addition, it was the highest quarterly shipment level since the first fiscal quarter of 2008. Sales into the Residential Roof Deck/Wall Assembly/Structural Insulated Panel Market increased by 208% during the period, and shipments into the Commercial Modular Market increased by 65%.

Dr. Michael Huddy, Barrier Technology CEO, commented: "We are pleased to see that the Pyrotite® technology private-label agreement we announced in January of 2010 with LP® Building Products is beginning to take shape. Coupled with our ongoing relationship with MuleHide Products in the commercial modular market, Barrier is successfully dealing with the lingering depression in the construction industry. Barrier is growing at record pace; on par with levels in 2008. We attribute this growth to an increase in captured market share for fire rated building materials created by new product applications for Pyrotite technology and the nationwide marketing, sales, and distribution sources our private-label partnerships provide."

Dr. Huddy concluded: "We continue to create success by targeting sales efforts toward architect and specifying engineer educational seminars which focus on applications requiring fire-rated material on exterior roofs and walls of multi-use commercial buildings. This market provides our private-label partners with strong growth potential as individual projects in this market can require significant volumes of Barrier Pyrotite^® products. With current capacity levels at our manufacturing facility near 40 million sq. ft., we have significant room for growth and are confident we can keep pace with demand from our partners in the near term."
