ADI
specializes in suspended acoustical ceilings, including metal and wood
ceilings and walls. Bill and Betty Lee Cramer founded the company in
1965, and it is now celebrating its 58th year of operation. In April
2023, James and Heather Chaney purchased ADI, which is based in Kent,
Washington.
Bill was a military veteran who earned a degree in
forestry from the University of Washington. His early career was in the
dimensional lumber business. He was soon asked to work in the newly
formed Acoustical Ceiling Tile division of the lumber company. At that
time, the acoustical ceiling business was all glue tile made of wood or
mineral fiber. Shortly after Bill joined the ACT division, the use of
metal suspension systems (T-bar, grid, etc.) came into use and
jumpstarted the industry, leading it to where it is today. Bill went on
to form ADI in 1965.
