Acoustical Value Maintained on Nu-\(/ood Kolor-Fast

Results of tests just released from the River Bank Laboratories show that the new type of coating on Nu-Wood Kolor-Fast makes possible the same high degree of acoustical value as the former product. Nu-Wood Kolor-Fast, according to these tests, has a noise reduction factor of .35.

C. C. Heritage, technical director of the Wood Conversion Company, upon receipt of these tests said, "It is most gratifying to know that the things we had hoped for when developing Nu-Wood Kolor-Fast have been realized. One crlso INTERIOR IAMBS

Notice thct the openingn between libres eize qad depth 6 of the important advantages of Nu-Wood Insulating Interior Finish is its acoustical value. When work started on the development of a fade-proof product, many felt that it would not be possible to get light-fast qualities and at the same time maintain a reasonably high degree of acoustical value.

"In coating Kolor-Fast we have developed a method whereby each surface fibre is coated individually. When the fibres are matted into insulation board units, tiny spaces are left between the fibres. These spaces are not visible to the eye, but the structure of the board is plainly shown in microphotographs. Such photographs made in the early development stages lead us to believe that the acoustical value of Nu-Wood would be maintained. However, the recent reports giving us the proof are most gratifying."

Samples and information on Kolor-Fast can be had ftom the Wood Conversion Company, Saint Paul, Minn.

New Booklets by Red River Lumber Co.

The Red River Lumber Co., Westwood, Calif., has just published two illustrated booklets, "California Pine Timber Lands and Mill Sites For Sale," and "Incense Cedar Venetian Blind Slats."

In offering timber tracts for sale, the company is carrying on a policy it has follorved for over half a century. Pioneering the development of pine lands in Minnesota and California, it has acquired large tracts from which selected areas have been sold from time to time, to other mill operators large and small. The "shingletorvn Tract,' offered for sale, a panoramic view of rvhich is shown in the booklet, is a part of the virgin forest owned by the company on the West slope of the Sierra.

The manufacture of Incense Cedar Venetian Blind Slats is a further development of diversification of the products of the Westwood plant and extends the utilization of the company's forest resources. The book emphasizes that the true Venetian blind is made of wood. Wood, by its substance and texture, combines the qualities necessary for Venetian blind performance. Wood, because it is a good non-conductor of heat can catch and disperse the light of the sun without also radiating the sun,s heat; it combines elasticity and strength with soft texture so that the inflow of air can be regulated without clashing noisily in the breeze; it blends with the wood trim and furniture of the home and gives a decorative harmony.

In the Venetian blind field Incense Cedar has met with success and holds a high place in acceptance by the trade.

A large percentage of "Paul Bunyan,, slats are undercoated. A specially developed formula combines a sealerprimer and pigment coat. Mechanically applied, this treatment is uniform. The undercoat is unique for its perfect smoothness and thorough sealing of the wood; it protects slats from atmospheric change and eliminates many manufacturing problems for the manufacturer of blinds; and the slats are ready for a one-coat final finish without sanding or other preparation. paul Bunyan,s undercoat slats are now standard specification by many manufacturers of blinds, large and small.

If slats are to be re-shipped or if they are to be stored where dust or smoke can get to them, the sealed package is recommended. It keeps the slats as clean and unmarred as when they came from the production line.

End labels display width and length in large figures, easily visible to the tallyman. The sealed package is bound with colored gummed tape, each grade has its distinct color, another convenience for checking inventory.
