International Barrier Technology, Fire-Resistant Product Manufacturer, Announces the Addition of Sales Representation in Southern California and the Midwest


WATKINS, MN and VANCOUVER, BC--(Marketwire - August 30, 2007) - International Barrier Technology Inc. ("Barrier") (OTCBB: IBTGF) (TSX-V: IBH), a manufacturer of proprietary fire-resistant building materials, is pleased to announce the addition of two sales representatives that will focus on market development of Blazeguard Fire-Rated Sheathing in two targeted regions.

Wayne Crutchfield has joined the Barrier team and will be responsible for developing the Blazeguard market in Southern California. Wayne has spent many years in the construction industry working for a major distributor in Southern California. He has built key relationships with architects, other distributors, and builders throughout the territory. With the State of California's recent adoption of the International Building Code, all new multi-family construction will be required to meet the fire-resistant building codes that Blazeguard is designed for.

Jim Dukart has joined Barrier as a Sales Representative in the Midwest region. He is taking on the responsibility of continuing growth in the upper Midwest, but also to expand the territory to include the Chicago and Kansas City regions. Jim has many years of experience in the sales industry and product development. In his most recent endeavour as Vice-President of Sales and Marketing for Sea-Legs, he grew sales of a start-up product by 1,900% in two years.

"The State of California printed a new building code which is based on the International Building Code currently used in almost every region of the U.S.," states Dr. Michael Huddy, President and CEO of Barrier. "California will officially adopt this new code, favorable to Blazeguard applications in roof and wall assemblies, on January 1, 2008. Mr. Crutchfield will help Barrier introduce Blazeguard into wall and roof applications that will feature not only fire, but also earthquake protection. Mr. Dukart, a Minnesota native, with considerable sales, marketing, and communication experience has hit the ground running already by picking up the initiatives Barrier established over the last two years. We are confident that Mr. Crutchfield and Mr. Dukart will impact Blazeguard sales in a dramatic and positive fashion by helping Barrier increase market share in these high priority markets."
