WISA-Hexa is a plywood panel coated with brown or grey film and imprinted with a hexagonal pattern intended for use as flooring in the transport industry, i.e. Some marine plywood has a Lloyd's of London stamp that certifies it to be BS 1088 compliant. It is a very flexible, sustainable, natural, non-toxic and durable material and some grades are very finely finished and highly suited to furniture type applications, as well as structural and wall making or lining. Many of these programs offer tax benefits to both the manufacturer and the end user. Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. : Smooth surface and accurate thickness combined with the durability of the material makes birch plywood a favorable material for many special end uses e.g. Full pack quantity: 33 Reverse side permitting jointed veneers, large knots, plugs, etc. Softwood Plywood is plywood which has a face and back veneer of softwood as opposed to a hardwood such as Birch, Maple, Oak, etc. For greater strength properties the veneers are laid crosswise, i.e. "Hughes H-4 'Spruce Goose'. 12mm Latvian Birch Plywood Throughout BB/CP 2440mm x 1220mm (8′ x 4′) Birch plywood is made from only Birch veneers of the same thickness, glued and laid up in alternating directions to the required thickness. Plywood produced to "E0" has effectively zero formaldehyde emissions. That is, it's not waterproof. By choosing WISA, you have the confidence that the plywood and veneer come only from legal, sustainable sources and conform to all relevant standards and regulations, including the European Union Timber Regulation (EUTR). WISA-Form Beto is a coated special plywood for less demanding loose panel concrete shuttering (mainly slabs) where the high strength of birch is not required. Programme for the Endorsement of Forest Certification (PEFC) Forest Stewardship Council (FSC), Leadership in Energy and Environmental Design (LEED), Sustainable Forestry Initiative (SFI), and Greenguard are all certification programs that ensure that production and construction practices are sustainable. Plywood was also used for the hulls in the hard-chine Motor Torpedo Boats (MTB) and Motor Gun Boats (MGB) built by the British Power Boat Company and Vosper's. Tropical plywood is superior to softwood plywood due to its density, strength, evenness of layers, and high quality. Learn More. Most notable is the British de Havilland Mosquito bomber, with a fuselage made of birch plywood sandwiching a balsa core, and using plywood extensively for the wings. Tropical plywood is widely used in the UK, Japan, United States, Taiwan, Korea, Dubai, and other countries worldwide. As responsibility is at the core of UPM's Biorore strategy, all businesses are committed to continuous improvement and replacing fossil materials - aiming to mitigate climate change. Panels measure 2400 mm x 600 mm in 18 mm or 22 mm thicknesses – ideal to install in all joisted or floating floor applications. Better grades also tend to be lightweight, strong, and virtually free of defects. This grade is often used for sheathing the surfaces of a building prior to being covered with another product like flooring, siding, concrete, or roofing materials. "WISA plywood is considered a valuable ingredient in our profession and is equally valued in our Department at Kingston School of Art. Films and laminates imprinted with various patterns improve the panel's frictional properties. : Phenolic resin film coated (Film Faced) plywood is typically used as a ready-to-install component e.g. UPM Plywood manufactures high-quality WISA ® plywood and veneer products mainly for construction and transport industries and the new thermo-formable UPM Grada ® wood material for the form pressing industry. All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called cross-graining and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. Strong standard construction can be optimised even further by using strength oriented construction when needed. Learn More. Plywood panels manufactured for structural applications are built up from multiple layers or plys of softwood veneer that are glued together so that the grain direction of each layer of veneer is perpendicular to that of the adjacent layers. Plywood as a building material is very widely used due to its many useful properties. Coatings, CNC-machining and cutting-to-size convert plywood panels into ready-to-install products. However, many countries’ forests have been over-harvested, including the Philippines, Malaysia and Indonesia, largely due to the demand for plywood production and export.[12]. The fuselage had exceptional rigidity from the bonded ply-balsa-ply ‘sandwich’ of its monocoque shell; elliptical in cross-section, it was formed in two separate mirror-image halves, using curved moulds. It is a good-quality, hardwood plywood made with waterproof glue, but since it's not treated with chemicals it is not rot-resistant. WBP is the most durable classification. Active R&D work and extensive traditions have shaped our production processes … Plywood for flooring applications is often tongue and groove (T&G); This prevents one board from moving up or down relative to its neighbor, providing a solid-feeling floor when the joints do not lie over joists.

The coating replaces the additional anti-slip mats, which are thrown away after use. The sheets are then patched, graded, glued together and then baked in a press at a temperature of at least 140 °C (284 °F), and at a pressure of up to 1.9 MPa (280 psi) (but more commonly 200 psi) to form the plywood panel. In his patent applications, he described the concept of laminating several layers of veneer with glue to form a thicker piece – the first description of what we now call plywood. [4] Bentham was a British naval engineer with many shipbuilding inventions to his credit. Aircraft plywood is available in thicknesses of 1⁄8 inch (3 mm) (3 ply construction) and upwards; typically aircraft plywood uses veneers of 0.5 mm (approx 1/64 in) thickness although much thinner veneers such as 0.1 mm are also used in construction of some of the thinner panels. Grading rules differ according to the country of origin. Subfloors are at least 3⁄4 inch (19 mm) thick, the thickness depending on the distance between floor joists. It is an economical, factory-produced sheet of wood with precise dimensions that does not warp or crack with changes in atmospheric moisture.
