NOTE ** The Homasote Company manufactures various products for the building industry. This section covers only a part of their product line: "440 Homasote(R)," "Super 440," "Sound-A-Sote(tm)," and "440 Carpet Board" sound-deadening boards. These boards are made from 100 percent recycled material, contain no asbestos or urea formaldehyde additives, and are treated to resist moisture, termites, and fungi. The resulting products combine structural strength, sound-deadening, and resilient qualities, with twice the insulation value of wood (Class III or C flame spread). There are no laminations, and no splinters, knots, or voids.
