Next..... Other Covering Materials, Aside from gypsum-board, you might also use paper board, which is available in extra-large-sized sheets, up to 8 to 18'. While awkward to handle without assistance, they speed up wall construction. Fewer joints result, and nail-spacing may be greater. Thickness is a bout 1/2", and 1 1/2" nails are used, usually No.9 flatheads, galvanized or cement-coated. Nails are placed 10 to 12" apart along the edges and staggered on alternate studs through the center sections at similar intervals. For sheet this size, 1/8" spaces are left between sheets to allow for expansion. Paper board may also be glued to studs and framing with special glue provided with the sheets. Cut with a knife or saw. Finishing can be done with wallpaper, paint or textures.
Another material is fiber board, usually made from wood pulp. It is light in weight, usually available in 4' widths and lengths from 6 to 8' up to 12'. They from a wall that is insulated by the material itself and, for the most part, provide sound-deadening qualities. Some are available in square tile form. Application is on furring strips except in the cases where, by means of adhesives, they may be attached directly to the wall as a flush surface. Others are beveled and the arrangement of panels will add eye appeal in lines or checkered squares. For attaching to furring, the usual nail is a 2d type, blued, or No.17 flat head brad. Being soft, these fiber boards may be attached to furring with staples. Since fasteners should be spaced at 4" intervals, staples are real time and labor savers.Where a thicker variety of fiber board is used, longer nails up to 1 1/2" are required. The material can be cut with a knife or saw. Where rough-edged fiber board is applied to wall and ceiling with butt joints, a crack filler is used, frequently with a paper strip to conceal crack and nail heads. Many types of fiber board are available ready-finished and require no more attention, once in place. Other can be papered, painted or finished with texture paint that will also fill in cracks and cover damage.
