waferboard

Aspen is especially good for panel products such as oriented strand board and waferboard.

Oriented strand board was created in the late 1970s as inventors extended the use of waferboard.

A "subfloor" of plywood or waferboard is then laid over the joists.

The company's waferboard sales last year totaled more than $500 million, Mr. Lacter said.

When SaskFor opened the new oriented strand board mill, the old waferboard plant was shut down.

Easier to choose among manufactured wood panels are particleboard, waferboard, oriented strand board and hardboard.

By filing inaccurate information, the authorities said, Louisiana-Pacific consistently beat its competitors in getting new waferboard plants into operation.

Most wooden sheds consist of precut plywood or waferboard panels, often with doors attached, that must be screwed and nailed together.

Panels are made of super materials: the plywood waferboard on the outside with a core of five-and-a-half-inch polyethylene."

By 1991, the company had grabbed nearly half of the growing market for waferboard, a plywood substitute made from wafers of wood glued and pressed together.

Waferboard belongs to the subset of reconstituted wood panel products called flakeboards, which is a type of particleboard.

Investment analysts say the company now controls 43 percent of the $1.2 billion waferboard market, which is one of the fastest-growing sectors of the construction materials industry.

In Maine, Louisiana-Pacific sought construction and environmental permits in 1981 for a plant that it said would produce 240 tons of waferboard a day.

Oriented strand board, called O.S.B. for short, is a more carefully manufactured waferboard and is stronger overall than the ordinary variety.

Though waferboard can be made from less-expensive wood like aspen and scrub pine, carpenters say it is as strong and nearly as versatile as plywood.

The Cabinet also suspended provisions of the trade pact that would have eliminated Canadian tariffs on some grades of plywood and waferboard from the United States.

They're the equivalent of doodles, in red and yellow and a variety of in-between blues and pinks that compete with the buzzing pattern of the waferboard itself.

Some types of exterior sheathing, such as asphalt-impregnated fibreboard, plywood, oriented strand board and waferboard, will provide adequate bracing to resist lateral loads and keep the wall square.

Used chiefly as an inexpensive substitute for lesser-grade plywood, waferboard is similar to Exposure 1 plywood in water resistance; also, it holds nails and other fasteners more strongly than either particleboard or plywood.

Underestimating Pollution Officials in the eight states said the company had avoided the more stringent review by deliberately underestimating, often by thousands of tons a year, how much pollution the new waferboard plants would produce.

But in a routine inspection in 1988, the Maine authorities found that the plant was producing 400 tons of waferboard a day, and that air pollution was far above the levels approved in the original permit.

His new works, 11 of them, are painted and shaped pieces of waferboard, two or three feet wide at most, the shapes vaguely like flattened birds' wings or fish or snails or, well, who knows what?

A few years ago, Mr. Tuttle made some shaped reliefs out of waferboard, a patterned wood composite, which he painted partly with lines and forms that also tapered and turned, the results being jaunty and sweet.

Under the 1977 amendments to the Clean Air Act, companies operating in regions with the cleanest air - like the forested areas in which most plywood and waferboard mills are situated - must undergo stringent review.

These critics said the penalty against the Louisiana-Pacific Corporation, the nation's largest manufacturer of wood-fiber construction panels, was minor compared with the enormous market advantage the company had gained by breaking environmental laws in reporting pollution from plants making waferboard.
