Pqck River Producing 'Tenex'
Pioneering Kochton Plywood Firm Gefs Firsi Shipmenl of 'Wood Wqfer' Boqrd
Newest entry in thc field of manufactured boards for interior use is announced by Pack River Tree Farm Products of Spokane, Washington, rvhich is beginning distribution of a distinctive waferboard which combines the unique appearance of a three-dimensional pattern with exceptional strength and stability Trade name of the new decorative material is Tenex. I'" is being manufactured in 4x8' and 4x16' sheets, /a-inch thick.
Tenex, although superfrcially resembling some products in the particle board field, differs radically in physical characteristics from either particle or hard boards. It contains neither ground nor defibrated rvood. Thin wood wafers are bonded under heat and pressure with chemical resin to make a solid rvood board that closely approximates the properties of natural wood.
Laboratory tests. as well as actual usage, show that Tenex can be handled and worked with ordinary hand or power tools just as natural wood is.In the same manner, conventional finishing may be employed. Because of the wafer pattern, however, novel and unique finishes also are easily obtained.
One large user reported, after working with Tenex, that "it is a very stable material, and lays and works absolutely flat and level. It sarvs perfectly, using either a table saw, band saw, jig saw, or sabre saw." He added that Tenex glues well and on various edge sanding operations it leaves nothing to be desired.
Tenex is being manufactured in a new $1,000,000 plant built by Pack River Lumber Company at Sandpoint, Idaho. The firm's president, J. I't. Brown, Jr., became interested in wood waste utilization some years ago. He r'vas attracted to the idea of a new dry process for manufactured board conceived by James d'A. Clark of Longview, Wash. The process contemplated the use of debarked slabs and edgings from the sawmill, as u'ell as trims. These constituted some of the finest wood in the tree but, in a lumber manufacturing operation, had of necessity to go to the sarvmill burner.
In 1950, Brou,n established a small research laboratory in charge of D. L. Haynes, norv vice-president in charge of research and development. Tt established practicability of the Clark process and in 1954 construction rvas begun on the
