International Barrier Technology -- Fire Resistant Building Materials Company Reports Record YTD Revenue; Record Sales Volume for November 2006

Growth Remains Strong in Residential Roof Deck and Commercial Modular Markets


WATKINS, MN and VANCOUVER, BC -- (MARKET WIRE) -- December 13, 2006 -- International Barrier Technology Inc. ("Barrier") (OTCBB: IBTGF) (TSX-V: IBH), a manufacturer of proprietary fire resistant building materials, is pleased to report record year to date sales revenue and sales volume shipped. Four million, three hundred ten thousand, nine hundred sq. ft. (4,310,900) of Blazeguard products have been shipped year to date. This is an increase of 55% from the 2,777,900 shipped during the same period last year. Shipments for the month of November were 742,700 sq. ft., up from the 687,500 shipped in November 2005.

Year to date sales revenue increased 33% from $2,385,476 to $3,178,579. During this period sheathing costs, which are a pass through commodity, continue near all-time lows. This kept top-line sales revenue lower that what it could have been had sheathing prices been at or above average historical prices.

Sales volumes into the residential roof deck market grew 82% to 2,518,000 sq. ft. during this time and commercial modular sales rose 28% to 1,777,900 sq. ft.

"The additional production from the new manufacturing line has enabled Barrier to meet the increased demand for our products and helped to reduce lead times for shipment," states Dr. Michael Huddy, President. "While regional inventory adjustments in some townhome markets will impact the rate of sales over the winter months, steadily increasing commercial modular sales will set the stage for continued strength in overall sales volume."
