Alpha Pro Tech, Ltd. Announces ICC Approval for Roof

Underlayment Product

NOGALES, ARIZONA - December 20, 2006 -- Alpha Pro Tech (AMEX: APT; CHX:APT), a leading manufacturer of products designed to protect people, products and environments, including disposable protective apparel and building products, today announced its roof underlayment product for the construction industry has received the highly coveted International Code Council (ICC-ES) approval. The ICC governs the International Building Code (IBC) which oversees most building departments around the country. This approval significantly expands the opportunity for Alpha Pro Tech’s roof underlayment product as many construction supply companies require this certification to sell the product.

ICC-ES is the United States’ leader in evaluating building products for compliance with code. A nonprofit, public-benefit corporation, ICC-ES performs technical evaluations of building products, components, methods, and materials. The evaluation process culminates with the issuance of reports on code compliance, which are made available free of charge to code officials, contractors, specifiers, architects, engineers, and others with an interest in the building industry and construction. ICC-ES evaluation reports provide evidence that products and systems meet code requirements. The International Code Council, a membership association dedicated to building safety and fire prevention, develops the codes used to construct residential and commercial buildings, including homes and schools. Most U.S. cities, counties and states that adopt codes choose the International Codes developed by the International Code Council (ICC).

“This approval is the final milestone required to clear the product for distribution throughout the construction industry,” commented Al Millar, President of Alpha Pro Tech. “This approval, which requires rigorous testing and inspection, also serves as a meaningful validation of our product, demonstrating its technical capabilities and ensuring construction companies that our roof underlayment will meet appropriate technical specifications. We are excited to have received this approval, and look forward to reaching a larger and more receptive audience. We estimate the market for roof underlayment products to be approximately $1 billion per year in annual sales, and with this certification, we are well-positioned to further penetrate this market.”
