NOGALES, ARIZONA - June 3, 2004 -- Alpha Pro Tech (AMEX: APT; CHX:APT), a leading innovator and manufacturer of proprietary materials for disposable protective apparel and consumer products, today announced it has entered the construction supply weatherization market with the formation of Alpha ProTech Engineered Products, Inc., a wholly-owned subsidiary. The company expects to begin manufacturing and distributing a building wrap product as well as a synthetic roof underlayment. The new company has hired Bruce Hayden, a veteran of the construction industry, to build the distribution channels and drive demand as Vice President of Sales and Marketing. Mr. Hayden was the Director of Sales and Marketing for a leading manufacturer of construction products for the residential housing market for the past eight years.

Al Millar, President of Alpha Pro Tech commented, “This announcement is a natural extension of our core capabilities: creating proprietary products designed to protect people and environments. Our expertise has now allowed us to create unique and improved materials which will better protect homes and offices from the environment and nature’s elements, while improving efficiencies and reducing expenses for contractors and homebuilders. With two million privately-owned housing units authorized by building permits annually in the USA according to the US Census Bureau, new home building will be a natural target and we expect about 80 percent of our sales to be generated from this portion of the market and 20 percent coming from the restoration and repair market in both residential and commercial building. We look forward to introducing our exciting products and anticipate booking sales during the fourth quarter of 2004.”

“Bruce Hayden joined the company bringing his years of expertise in the manufacturing and sales of building products. He brings exceptional energy and a proven track record to Alpha ProTech, and I am confident he will create widespread awareness for our innovative products while building a substantial distribution network,” Mr. Millar continued. “This business has the potential to add significant growth for Alpha Pro Tech, leveraging both our manufacturing techniques and our proprietary materials into an exciting new market for us. We welcome Bruce to the Alpha ProTech team and look forward to great successes for this important new subsidiary.” Al Millar went on to say, “Our commitment to this opportunity will also include a 30,000 sq, foot building and an initial investment of machinery and equipment which is consistent with our planned capital expenditures.”

The company will target distributors who have established relationships and developed channels for selling roofing and construction materials. The first two products expected to be sold by Alpha ProTech Engineered Products, Inc. will be a building wrap and a synthetic roof underlayment. The usage of these two products offers great advantages in decreasing the time it takes to construct a home as well as offering cost reduction. The building wrap will offer a tremendous weather resistive barrier and, to the home owner, years of lower energy consumption. The proprietary synthetic roof underlayment has the ability to resist the environment, as opposed to conventional organic roofing underlayment that are prone to rapid degradation & mold growth.
