- 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.
