We all know that Plywood is one of the best materials to be used for indoor construction purposes, personal projects, facing veneers of a different material, making furniture more resistant to damage and moisture, and so on. Individual panels are then cut from the mats into finished sizes. (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. A wide variety of oriented strand board uses options are available to you, All Rights Reserved. A few facts about wood. OSB is also used in furniture production. Some manufacturers treat the wood chips with various borate compounds that are toxic to termites, wood-boring beetles, molds, and fungi, but not mammals in applied doses. Plywood vs. OSB (Oriented Strand Board): Major Differences . Safety Data Sheet (SDS) Weyerhaeuser Oriented Strand Board ( OSB) Products including: Sheathing, Edge â¢, OSB is engineered for strength and designed for a variety of applications. All wood-based structural use panels can be cut and installed with the same types of equipment used with solid wood. OSB is a material with favorable mechanical properties that make it particularly suitable for load-bearing applications in construction. That's ⦠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 ⦠The layers can vary in thickness to give different finished products.Plywood is made from good log called peelers. The strips are sifted and oriented in belts or wire cauls. Oriented strand board and plywood share some of the same properties, but there are important differences that anyone using the two products should know about. Or use âSquare Edgeâ⦠You did not provide a valid email address. Its performance has allowed OSB to gain entry into new markets, Unlike plywood, which is built up from thin layers of wood veneer, OSB consists of strands of wood. 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. One-third of the United States ⦠OSL is produced by aligning long strands of wood in parallel and binding them together using adhesives, pressure and heat. Standard Smartply OSB Panels and Sheets. Add to basket. Most of the world's OSB is made in the United States and Canada in large production facilities. The result is a solid panel with no core gaps that will not delaminate under normal use. Finished panels are available in large dimensions, minimizing the number of joints that can "leak" heat and admit airborne noise. 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]). Unlike itâs plywood counterpart, OSB lacks the forces that tend the wood to warp, and so is easier to get perfect dimensions and avoid warping tendencies.The one major disadvantage of OSB is its propensity to expand with moisture. Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives.It is typically used for headers, beams, rimboard, and edge-forming material.LVL offers several advantages over typical milled lumber: Made in a factory under controlled specifications, it is stronger, straighter, and more uniform. The sheets are generally 4 x 8 or 4 x 12 feet in size. Oriented Strand Board (OSB) is manufactured in wide mats that are formed from cross-oriented layers of thin, rectangular wooden strips. It uses less wood to make more wood products. 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. OSB is beneficial in that it uses small-dimension and waste wood for its fiber; however, resin type should be considered for human health impact, and the production process monitored for air-pollutant emissions. The finished sheet size varies by country. OSB is now used for about 70 percent of all floor, wall and roof sheathing in North America. In 2005, Canadian production was 10,500,000 m2 (113,000,000 sq ft) (3⁄8 in or 9.53 mm basis) of which 8,780,000 m2 (94,500,000 sq ft) (3⁄8 in or 9.53 mm) were exported, almost entirely to the United States. 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. 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. It also describes where Performance Rated panels are used and provides updated trademark and performance category information. The number of layers placed is determined partly by the thickness of the panel, but is limited by the equipment installed at the manufacturing site. Plywood usually produces pieces of furniture that are dull-looking unless coated with stain or paint. PR-N136: Georgia-Pacific Wood Products LLC, ESR-2586: APA – The Engineered Wood Association.

APA-trademarked OSB is suitable for a variety of end uses including subflooring, single-layer flooring, wall and roof sheathing, sheathing ceiling/deck, structural insulated panels, webs for wood I-joists, industrial containers, mezzanine decks, and furniture. 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. However, pieces of furniture built using OSB do not require any staining or painting because the design of the board itself can stand alone. OSB looks a lot like a collage of different wood chips. Wood strips on the external layers are aligned to the panel's strength axis, while internal layers are perpendicular. The edges of OSB will dramatically expand (>15%) when wet, and takes much longer to return to normal size. [1] OSB may have a rough and variegated surface with the individual strips of around 2.5 cm à 15 cm (1.0 by 5.9 inches), lying unevenly across each other, and is produced in a variety of types and thicknesses. Oriented strand board (OSB) is a completely different material than the previous two mentioned. Oriented strand lumber (OSL) is a structural material with very consistent properties from one unit to another, and capable of handling large loads. The mat is placed in a thermal press to compress the flakes and bond them by heat activation and curing of the resin that has been coated on the flakes. Oriented strand board (OSB) is a completely different material from the previous two mentioned. This mat is then cured, trimmed to size Thickness: 6mm, 8mm, 12mm, 18mm, 21mm. Sign In Failed. It was invented by Armin Elmendorf in California in 1963. OSB is produced in huge, continuous mats to form a solid panel product of consistent quality with no laps, gaps, or voids. In 2001, oriented strand board surpassed plywood in terms of square footage produced. The finished product has properties similar to plywood, but is uniform and cheaper. The design of the oriented strand boardallows using it the same way as plywood. 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. [2] It is now more popular than plywood, commanding 66% of the structural panel market. 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. sheathing, oriented strand board (OSB) is helping to shape how the world builds. Are you looking for the reasons why OSB is leaving behind Plywood for construction purposes? Describes OSB composition, properties, code acceptances, and applications. While OSB does not have a continuous grain like a natural wood, it does have an axis along which its strength is greatest. Oriented strand board was created in the late 1970s as inventors extended the use of waferboard. Kronospanâs Oriented Strand Board (OSB) Superfinish ECO offers a wide range of applications for both interior and exterior use.
