Perfect Plank Co.
Perfect Plank Co--A Corporate History
Roy C. Horne (1918-1987)
PERFECT PLANK is the creation of Roy
C. Horne, a graduate of the University of
Washington (B.A.1939, M.A., 1947) who
developed the concept for the product while
working as a research engineer for the Western
Pine Association (WPA), a trade organization
financed by the timber industry. Horne
specialized in developing methods of
improved waste utilization, and one of his
projects involved the use of finger-jointing to
salvage smaller pieces of wood that were
effectively being discarded by sawmills and
lumber remanufacturers. When none of the
association members expressed much interest
in the idea, Horne left the WPA and decided to
start his own company.
This proved to be a greater challenge than first contemplated. The initial
foray involved the establishment in 1953 of the Engineered Wood Products Co.
in Rocklin, California. This company produced PERFECT PLANK for less
than a year before the company’s investors elected to withdraw their support.
For the next several years Horne contracted with various lumber
remanufacturers to produce PERFECT PLANK, including Vaughn Millwork in
Reno, Nevada from 1955 to 1957, and High Sierra Pine Mills in Oroville,
California from 1958 to 1961. During this latter period, Horne was able to
obtain a patent (now expired) for the method that is still a critical element in the
production of its high-quality, glue-laminated products.
When High Sierra Pine Mills was purchased by Las Plumas Lumber Co. in
1961 , Horne bought the existing machinery from the new owner and, in 1961,
formed his own corporation, the present PERFECT PLANK Co. From 1961 to
1987, the company operated in a rented building on the property of Las Plumas
Lumber Co. (which later became DG Shelter Products).
During this period, each of Horne’s three sons joined the firm, including
Jim and Bob in 1974 and Terry in 1981. During the 1980’s, the company
considered a number of sites for re-location and, in 1986, finally found a
suitable facility on South Fifth Avenue, about one mile southwest of the original
plant. This eight-acre property included a factory and warehouse that had been
built by a chemical company that closed down after operating for only four
months. The property was purchased by a family partnership that rents the
facility to the corporation. It took more than a year to expand and equip the
existing buildings, and the company finally moved into its new home in
September 1987. Since the original expansion, the company has made numerous
additions to the facility that now includes 70,000+ square feet of offices, factory
The company's future was assured in 2010 when a third generation of the
family joined the corporation. Adam Horne, son of Terry, has the initial
responsibility of managing accounts payable and helping to man the sales desk.
