PLYWOOD & PARTICLEBOARD

(Continued from page 55)

We are extremely enthusiastic about the future of Com-ply in the building materials marketplace.

One of the most important economic factors is that Com-ply greatly increases the utilization of Southern pine timber resources. Com-ply uses literally the entire tree from top to bottom, converting all of it into structural building material.

There is no question that composite panels are equal to traditional plywood panels in every respect. We believe they are the-product of the future because of raw material scarcity and cost.

The lumber yield from a log in a typical sawmill today averages 30 to 4006, with the remainder used for pulp, fuel or other wood by-products. In plywood manufacture, only 45oh of a veneer log or peeler block is converted to plywood veneers.

Composite materials convert nearly 10006 of the peeler block to structural building products.

Three-quarter-inch tongue-andgrooved Com-ply floor panels and l/2" Com-ply roof sheathing were used for the demonstration home. The panels have an oriented flakeboard core and solid wood veneer facings of Southern pine. The flakes are oriented so their grain runs across the panel in the narrow direction opposite to the veneer grain for strength.

Floor panels were glued to the joists and along the tongue-andgrooved edges, increasing the stiffness of the floor and helping to seal the panel edges to prevent excessive air leakage from the plenum. The plenum replaces heating and cooling ducts in this prototype home.

Southern pine particleboard was used for the cores of composite floor joists. This house is the first onsite test for composite floor joists. Both nominal 2x8 and 2xl0 joists were used, in lengths up to 32 feet. All were spaced 24" o.c.

Years ago when I first entered this industry, I don't like to say how many, we were making plywood panels in every size from 3'x6' to scarfed panels up to 36' long. In those days I used to laugh and say, someday we'll just grind the wood up into a slurry, pump it into a tank car, ship the tank car back East, and let them extrude any size they want to. Maybe that won't turn out to be such a ioke after all.

While 1979 will be difficult, we should look on it as our industry's part in combating inflation and shoring up America's economic and monetary systems for the long term.

I am confident we will emerge from these troublesome times a stroneer nation.
