Our Company

Ward Process Inc. was founded in 1963 in Natick, Massachusetts as a fabricator of thermal insulation materials. American Acoustical Products was formed in 1972 as a wholly owned division of Ward Process to develop the growing range of acoustical materials.

Today our capabilities have expanded to include vinyl casting and extrusion lines for manufacturing barrier, composites and damping materials. Die cutting, laminating, embossing, sewing and assembly lines create a complete range of acoustical solutions.

In March 2006, American Acoustical Products moved most of its manufacturing to the new site in the Hopping Brook Industrial park converting an architectural award winning building into its new headquarters. The new acoustical laboratory was also moved to the new site and further expanded and improved.

We are now a well established ISO 9001 registered company in the thermal and acoustical manufacturing and fabricating manufacturing industry.
