Adjustments to the manufacturing process can affect thickness, panel size, strength, and rigidity. 08/27/2018 . The mark signifies that panel quality is subject to verification through APA audit—a procedure designed to assure manufacture in conformance with APA performance standards or the standard shown in the mark. For exterior wall applications, panels are available with a radiant-barrier layer laminated to one side; this eases installation and increases energy performance of the building envelope. [10] Industry trade groups assert that formaldehyde emissions from North American OSB are "negligible or nonexistent".[11]. It is primarily used as sheathing and underlayment for house construction and remodeling projects. We form the layers by shredding wood and then joining them together with adhesive. Oriented Strand Board is a widely used, versatile structural wood panel. The layers are created by shredding the wood into strips, which are sifted and then oriented on a belt or wire cauls. [3] The most common uses are as sheathing in walls, flooring, and roof decking. OSB is a material with favorable mechanical properties that make it particularly suitable for load-bearing applications in construction. Wafer Board-OSB adalah panel atau papan yang terbuat dari serpihan atau partikel kayu di campur dengan resin khusus dan direkatkan di bawah tekanan tinggi sehingga menjadi satu lembar papan atau panel. OSL is produced by aligning long strands of wood in parallel and binding them together using adhesives, pressure and heat. [5] Strand board can also be made from bagasse. All wood-based structural use panels can be cut and installed with the same types of equipment used with solid wood. It uses less wood to make more wood products. It was invented by Armin Elmendorf in California in 1963. The result is a solid panel with no core gaps that will not delaminate under normal use. OSB is engineered for strength and designed for a variety of applications. A plywood subfloor generally uses 1/2-inch to 3/4-inch-thick sheets of plywood that have one rough side (which faces down) and one smooth side, which faces up. Individual layers can also vary in thickness to give different finished panel thicknesses (typically, a 15 cm (5.9 in) layer will produce a 15 mm (0.59 in) panel thickness[citation needed]). Oriented Strand Board: Opportunities and Potential Products in China. Although oriented stranded board (OSB) has similar uses to plywood, it has a much coarser finish. The APA Product Support Help Desk is a free service available to answer your questions pertaining to the specification and application of engineered wood products and systems. But why is […] All Rights Reserved. 4' x 8', 4' x 9', 4' x 10'; manufactured in 8' X 24' or larger panels which can be custom-cut by most manufacturers. TallerDE2 Architects uses engineered wood to create adaptable Madrid apartment. These are bonded and arranged in a three-tier structure, with the strands in the outer layers oriented in the same direction as the panel length, and those in the core layer at right angles to it. Phenol-formaldehyde products are considered to be relatively hazard-free. General use Oriented Strand Board (OSB) conditioned for structural applications in humid environments. This can be seen by observing the alignment of the surface wood chips. Sheathing is the structural covering of plywood or oriented strand board (OSB) that is applied to studs and roof/floor joists and serves as a base for finish flooring or a building's weatherproof exterior. OSB Basics What is it, you ask? Oriented strand lumber (OSL) is a structural material with very consistent properties from one unit to another, and capable of handling large loads. Like particle board and MDF, OSB comes from wood shavings. (Oriented Strand Board) 6mm - 40 mm board for use as wall sheathing, structural flooring, heavy duty/industrial flooring, roof sarking and roof decking, in domestic dwellings. [8] When tested to failure, OSB has a greater load-bearing capacity than milled wood panels. Manufactured from waterproof heat-cured adhesives and rectangularly shaped wood strands that are arranged in cross-oriented layers, OSB is an engineered wood panel that shares many of the strength and performance characteristics of plywood. It differs from other wood-scrap products because its long strips of wood are placed strategically rather than randomly. Oriented structural straw board is an engineered board made by splitting straw and formed by adding P-MDI adhesives and then hot compressing layers of straw in specific orientations.
