VALDOSTA, GA.—October 21, 2005— Alpha ProTech Engineered Products, Inc., a wholly-owned subsidiary of Alpha Pro Tech, Ltd. (AMEX:APT) announces Notice of Acceptance from the Miami-Dade County Building Code Compliance Office for the Company’s AlphaProTector™-SUL Synthetic Roof Underlayment product.

The Miami-Dade Building Code Compliance Office is recognized as possessing stringent criteria for building products, due to the frequency of hurricanes and tropical storms in the region.  The Miami-Dade Notice of Acceptance for AlphaProTector™-SUL Synthetic Roof Underlayment demonstrates our compliance with all applicable building codes.  It will facilitate our exclusive distributor Perma “R” Products’ ability to sell our synthetic roof underlayment, as it is a standard for many builders nationwide.

Al Millar, Alpha Pro Tech’s President, commented, “This is a milestone event for this new segment, validating the quality of our roof underlayment and enabling our exclusive distributor, Perma “R” Products, Inc. to sell this innovative solution more easily to all customers.  The Miami-Dade Notice of Acceptance essentially serves as certification nationwide, as no municipality or governing authority has more rigorous standards than Miami-Dade.  We believe this will enable us to accelerate the expansion of this segment and further capitalize on this significant market opportunity.”

The AlphaProTector™-SUL Synthetic Roof Underlayment provides significant technological advances as a moisture barrier, as well as protection from growth of mold and other contaminants. Our roof underlayment can be left exposed for up to six months without degradation, is seven times lighter and twenty times stronger than traditional felt paper, is easier to install, is more durable and is more effective than competing products.

Perma “R” Products, Inc. is a leading manufacturer and developer of cutting-edge products for the building and packaging industries. The Company also owns General Panel Corporation, a manufacturer of Structural Insulated Panel (SIPS) for residential and commercial building markets. Also, Perma “R”
