For Immediate Release:

June 12, 2007

International Barrier Technology, Fire-Resistant Product Manufacturer, Continues Double Digit Growth in Commercial Modular Industry.

Watkins, MN; Vancouver, BC June 12, 2007 -International Barrier Technology Inc. (“Barrier”) (IBTGF: OTCBB; IBH: TSXV), a manufacturer of proprietary fire-resistant building materials, is pleased to report growth of 60% in Blazeguard shipments into the Commercial Modular Sector for the month of May.  For the month ending May 31, 2007 Barrier shipped a total of 744,352 sq.ft. of Blazeguard products, in comparison to 769,120 total sq. ft. from May 2006.  Of that total, 693,800 sq. ft. was shipped into the commercial modular segment vs. 432,700 sq. ft. last May.  For the month, $466,216 in sales revenue ($236,621 generated from the treatment of commercial modular products and $21,479 was generated from the treatment of Residential Roof Deck materials) was captured.

Year to date sales volumes continue to remain higher despite a continued slow down in housing starts.  Sales of Blazeguard products from July 2006 through May 2007 are 8,113,800 sq. ft. in comparison to 7,047,600 sq. ft. during the same eleven months last year.  This is an increase of 15%.  Sales revenues for those same time periods are $5,666,605 and $5,964,405, respectively.  However, sales revenues have actually increased by 6% after adjusting $626,503 for the decrease in pass through sheathing costs.  Sheathing costs have declined substantially due to the slowing demand.

“Barrier is very happy to have diversified in to the commercial markets back in 2004,” reports Michael Huddy, Barrier’s President and CEO.  “Thankfully while residential housing starts continue in the doldrums compared to 2005 and 2006, commercial business seems to be strengthening and offsetting the current decline in business to residential markets.”
