Fire Resistant Building Materials Company Reports 122% Growth in Commercial Modular Product Line

International Barrier Technology Breaks Record Monthly and Year-to-Date Sales Revenue and Volumes for the Period Ending February 28, 2007


WATKINS, MN and VANCOUVER, BC -- (MARKET WIRE) -- March 12, 2007 -- 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 and monthly sales revenue for the Commercial Modular Industry. Sales volumes of 380,300 sq. ft. of Blazeguard products were shipped into the commercial modular market for the period ending February 28, 2007. This is a 112% increase from the same period in the previous year. Total sales for the month of January were 447,632 sq. ft. Year-to-date, 5,933,900 sq. ft. of Blazeguard products have been shipped, which is an increase of 24% over the 4,775,400 shipped this time last year.

Sales revenue in the commercial modular industry during the month of February increased a dramatic 122%, as the market remains strong and new market share is captured. Blazeguard sales into the residential roof deck market were again impacted this month by softness in the housing market. Even though total sales revenue for February is down, year-to-date sales revenue is up to $4,284,617 from $4,063,533 reported last year. The pass through commodity, sheathing costs, continue at 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.
