The two popular forms of plywood are interior and exterior. Each plywood sheet is made after following a certain procedure. Different raw materials and procedures ensure that the ply sheets can be used for different purposes. While plywood is an artificially formed component of the construction industry, it has proved its versatility and usability by becoming the preferred choice of raw material around the globe. One can obtain the ply sheets locally as well as over the internet.
Each sheet of exterior plywood is made using plies or sheets from different trees. The trees that usually lend their wood are the Australian Eucalyptus, Birch, Yellow Pine etc. These sheets of wood are then glued together using a water resistant chemical and pressed together. This lends the exteriorplywood durability, strength, resistance to water, sustainability, toughness and other unique characteristics. While exterior plywood can be used for various purposes, it is usually used by construction agencies to make different pieces of furniture. Musical instruments and sports equipments are also made using this ply.
After treating the ply using chemicals, it is coated with another chemical to protect it from decaying on the outside. This makes the exterior plywood resistant to moisture from all angles. Since these sheets of wood are made to sustain harsh weather and moisture, they are the preferred choice of raw materials when it comes to building boats. Grading systems like the WBP – Weather and Boil Proof, assure the user of quality products which have passed various quality control checks. These ply sheets that are specially treated to resist moisture are usually priced higher than their standardized counterparts. One probably for the price hike is the chemical agents that are used for the treatment. Besides that, one can attribute the increase in price to the procedure involved.
To purchase exterior plywood is easy as long as you keep a few pointers in mind. While buying a ply sheet from any ply wood supplier, look for a mark stating APA or DFPA. These are agencies that regulate control checks on the manufacture of plywood. APA is short for American Plywood Association, while DFPA is Douglas Fir Plywood Association. While you can be assured of excellent quality veneer sheets from the organizations mentioned above, there are numerous others around the globe that work to establish acceptable standards worldwide. You could either refer to guides on the internet or information provided by your ply wood supplier for the same.
Exterior plywood is also a great source for building decorative articles. Usually, pieces made of decorative plywood are used as accessories to the existing furniture line but many companies come up with limited edition furniture that is made from them as well. When you purchase furniture from retails stores, you should be sure to check for quality seals and other essential grading standards. Even when purchasing plywood as a raw material, one must ensure that good quality products are being ordered by checking their grading authority and other specific details.
Plywood is basically a combination of multiple thin veneer sheets of wood. Birch plywood is basically characterized by smooth color and texture. Birch ply is usually layered; which is common knowledge in the lumber industry. Birch plywood is primarily used in a wide variety of home improvement and smaller construction projects. It is smooth on the surface and does not have any splinters or jagged edges. This kind of veneered plywood is usually used in construction of furniture such as cabinets, desks, shelves or children furniture.
Its thickness ranges from 3 mm to 36 mm. Birch plywood comes in a variety of sizes unlike other lumbers. Birch plywood is reasonably priced, very durably and is commonly available everywhere. Birch plywood generally goes into the construction of doghouses or dollhouses that are quite popular amongst kids.
Birch plywood comes in a treated and untreated variety. Sandpaper can be applied on one side or both sides depending on the customer’s requirement. It generally is smooth so sanding may not be necessary in most cases. Some applications may need a smoother texture so that is when a little bit of work has to be done. It can also be made in such a way that the exteriors are waterproof and the interiors are water resistant.
Birch plywood is generally misconstrued as one piece
of wood. But that is not the case. It is made up of multiple layers of birch veneer. These layers determine the thickness of the plywood. Sometimes it might just be the case that about 25 veneer sheets are glued together with a high quality glue or resin. The veneer sheet can be made of a number of birch varieties such as Jacquemonti birch, canoe birch, heritage river birch, yellow birch, whitebarked Himalayan birch or European birch. The place where Birchwood is found in plenty is Russia, Finland, Baltics, Estonia and Lativia. Europe is famous for its supply capacity.
Birch plywood is also used as industrial material. The turbine blades of windmills are made out of this plywood. The boxes of Liquefied natural gas are made out of birch plywood. It is commonly seen as signboards and road signs. Owing to its smooth texture, musical instruments are also made out of them. They are popularly used in sports material too. The smooth surface, accurate thickness and its durability make them a favorite material for special products.
Other features of birch plywood include a resistance to humidity. It is also very easy to reprocess it and very easy to handle. In some types of birch faced plywood the panel surface can be altered or improved depending on its application. It is important to have the accurate weight to strength ratio. They are also light weight which makes them the automatic favorite for home appliances.
