Fiberboard sheathing

Fiberboard sheathing used in fiberboard sheathing, interior ceilings, and roofs is made of wooden fibers held together with asphalt binder or resin.

Fiberboard was used indoors as both a finish-surface to be painted or as a base to which plaster and then paint were applied. This article describes and provides photographs that aid in identifying various insulating board sheathing materials used on building walls and roofs, such as Homasote, Celotex, Insulite, and Masonite insulating board sheathing products. InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website. Here we provide fiberboard product names and we describe the components, properties, and applications of various fiberboard, hardboard, and insulating board or sound deadening board products.

Structural exterior wall sheathing works with the building envelope to prevent wind and water from entering. Structural wall sheathing also ties framing studs together, makes the walls resistant to twisting and bending, and provides a surface for application of materials, like siding. However, many structural exterior wall sheathings, like OSB and fiberboard, lack sufficient strength, effective moisture management, may contain toxins, are difficult to handle, and have escalating and volatile pricing. Two common types of structural wall sheathing are oriented strand board OSB and fiberboard sheathing. They attach to the exterior wall framing and brace the walls against positive and negative forces. Both are wood products, which makes them earth friendly. However, there are several differences between OSB and fiberboard structural sheathing. Oriented strand board OSB is a panel sheathing made from hundreds of rectangular thin wood strands 1-inch by 4-inch flakes , arranged in cross-oriented layers. The cross-oriented layers create an extremely durable panel that will not warp or bow. The strands are hot pressed onto sheets with a resin and wax adhesives. OSB come in sizes up to 8 feet wide and 16 foot long and is used in commercial and residential construction. Fiberboard structural sheathing is an engineered product made with ground up wood chips and lumber waste glued together with an asphalt binder or resin.

Fiberboard products are also used for sound insulation, such as Homasote's SoundBarrier used on fiberboard sheathing and over subflooring or in ceilings.

Two different processes are used: wet process using water to distribute the wood fibers as they are formed into a mat, and a dry process that is similar but omits the water, often using heat and pressure. Illustration: a foam core structural insulated panel provided by Foam Laminates of Vermont, cited below.

With a background in construction and home renovation, Matt is well-versed in the latest trends and techniques in the industry. It is designed to fill the void of the outer walls. In addition to plywood, OSB, and gypsum board, impregnated fiberboard produced in 4 ft. Keep in mind that fiberboard products vary in color, thickness, density, texture, and coatings. Fiberboard sheathing does not hold screws well; it is also easy to strip the screw holes.

Matt's writing focuses on a range of topics, including windows, flooring, HVAC, and construction materials. In general, the harder the fiberboard product the more-likely you are to find it in thinner productions. It is more popular in certain regions of the country than others. Website: www. InspectAPedia tolerates no conflicts of interest. Humidity and water leaks produce entrapped moisture in exterior walls where molds are being developed. The R-value of fiberboard sheathing is higher than plywood, gypsum board, etc, and is rated at about R 2. OSB is susceptible to mold due to moisture intrusion. Each layer builds on the previous layer to produce a tighter bond, reducing the amount of moisture that can penetrate. Muench, New Orleans, assigned to Celotex Corporation, described a method and apparatus for drying sheets of artificial heat insulating lumber, preferably formed by the felting of bagasse fiber along with other materials necessary to make a satisfactory structural fiber board.
