Newest entry into the insulating board products field in the Pacific Northwest is the Wood Fiber Division of the Simpson Logging Company, which has constructed a modern insulating board plant at Shelton, Washington.

The new mill started production April 1, manufacturing in the first runs insulating building board and roof insulation.

The plant will manufacture a complete line of insulating board products, including building board, plank, lath, sheathing, decorative tileboard and roof insulation. They will be marketed under the brand name of Simpson Insulating Board Products. The full production of the new mill is allocated exclusively to lumber dealers in the eleven western states for western building. Twelve distributors covering the West have been appointed and have received first shipments oT the new products for distribution to their dealers.

Simpson will also invade the acoustical tile field with an improved perforated tile. It will be marketed in the eleven western states under the trade name of Simpson Acoustical Tile. Eleven distributor-applicator firms have been named.

The new Simpson insulating board products were developed by the Simpson research laboratory which discovered that the Douglas fir, grown on the 24o,000-acre Simpson Tree Farm and other timber holdings in the rain belt of the Olympic mountains in the state of Washington, produce an exceedingly long and stout fiber. When properly pro,cessed in manufacture, this long fiber results in an insulating board of unusual strength and high thermal value. Douglas fir wood is carefully sorted and all bark or rot is removed before chipping. Simpson Logging Company is the only company now using IO0/o Douglas Fir in the manufacture of insulating board and acoustical tile.

These new developments are a part of the Simpson Company's expansion program in the building material field. Up to the present time, production has been confined to lumber Trom, two sawinills, plywood from two plants, and doors and millwork from one of the largest plants in the industry.

The wood fiber plant is under the management of C. J. Macke, a vice president of the Simpson Logging Company. R. E. Seeley, vice president in charge of sales, has supervision over the sales of all company products. A. L. Crozier, who has been with the ,company a number of years, most of which have been as Eastern District Representative with offices in New York City, has been transferred to the main sales ofifice in Seattle as Sales Manager of the Wood Fiber Division. Sales engineer and technical adviser is Paul D. Close, nationally known authority and technical writer on insulation. Close joined the Simpson organization after serving 7 years as technical secretary of the Insulation Board Institute, Chicago.

"f believe our research laboratory and new Wood Fiber Division plant have developed and are manufacturing the finest, strongest insulating board on the market," commented R. E. Seeley, vice president in charge of sales for Simpson Logging Company.

"In production only a short time, the plant has achieved a high uniformity in the product. \Me are immensely proud of our new plant and of its high-grade insulating board products," continued Mr. Seeley.

'fhe new Simpson acoustical tile has a high sound-absorption value due to the Douglas fir fibers and clean, drilled perforations of which there are 484'to the 12" x 12" unit. The tile is attractively finished in oyster white, as is the bevel. It is made in two sizes, 12" x 12" and 12" x 24t, and in thicknesses of tl", 5/g" and 7/8".

The insulating board products are made in standard sizes and thicknesses; the building board, decorative tileboard and plank are finished one side in oyster white.

Despite the current shortage of insulating board products in the market, a broad and intensive advertising and merchandising compaign is being launched this month. Special emphasis will be placed on point-of-sale material for dealers.

While an old and honored name in the Pacific'Northwest, the Simpson Logging Company may be new to some dealers in far corners of the eleven western states. The Simpson Logging Company was organized in 1895, and is one of the oldest and most progressive wood products concerns in the Pacific Northwest. It maintains extensive operations in southwest Washington, with headquarters at Shelton. A continuous and ample source of supply of prime Douglas fir fiber 'for manufacture of Simpson insulating board products is guaranteed through the operation and maintenance of the Simpson Tree Farm timber holdings in the Olympic mountains. The Tree Farm, as well as other holdings, guarantee a continuous succession of crops of Douglas fir. Trees are grown under intelligent, scientific forest management which includes nurseries for cultivation of seedlings for replanting; protection of the forests from fires, insects, disease and fungus.

The new wood fiber plant started production shortly after the Simpson Logging Company executed a 100-year agreement with the U.S. Forest Service. This 100-year program places the so-called Shelton Working Circle on a sustained yield basis, which in efiect assures a theoretical perpetual timber supply. The wood fiber plant ties in logically with the company's sustained yield program. By utilizing every part of the tree to the fullest extent possible, the volume of timber logged will be reduced considerably without reduction in the total quantity of forest products manufactured. The program so far has resulted in increased employrnent within the Shelton Circle, while the actual drain on the timber supply has remained cons' tant.
