Armstrong's Cork Machinery Isolation is a special grade of. corkboard for absorb ing noise and vibration under moving machines such as fans, motors, etc. The natural resilience of cork and the fact that it does not "set" under pressure^ nor harden with age make it especially suitable for this use. Another advantage of Armstrong's Cork Machinery Isolation is that, being a manu factured product, its density can be varied to suit different conditions. Armstrong's is made in'six grades, or densities, from 1.1 to 1.66 lb. per board foot. By adapting the grade to weight and type of machine, much better results are obtained than by using a single grade for all installations. Armstrong's Cork Machinery Isolation is made in boards 12 by 36 by 1, 1V, 2, 3, 4, 5 and 6 in. thick. The standard boards may be sawed or cut into the desired shape or size as readily as lumber, and where large pads are required, they can be made in sections and cemented together. The density and thickness to be used cannot be determined accurately until such factors as the weight, speed and character of the machine to be isotated are known. Generally speaking, the grades which should be used under different classes of machines are as follows: Small fans, motors, generators, etc....... 1.10 to 1.20 Large fans, medium size motors and generators, light machines and ma chine tools, etc.................... .............. 1.25 to 1.33 Heavy motors and generators, large machines and machine tools, en gines, etc.-- 1.50 to 1.66 Two methods of installing Armstrong's Cork Machinery Isolation are usually fol lowed. In the first, the foundation pits are lined with Armstrong's Cork Ma chinery Isolation on the bottom and sides. The foundation proper is then poured in on top of the cork. In the second, the cork is placed between the base of the machine and the foundation, floor or ceil ing, to which it is fastened.
