In this life, we always choose something: apartment, work, building materials. Particularly carefully selected the necessary building materials for finishing apartments and country houses. Here the main thing is not to sell it cheap, so that in the future you can not fly "like plywood over Paris". What are the criteria for choosing OSB plywood?

What is OSB plywood?
Wood and wood-chip materials occupy, and will occupy a leading place among construction materials. More practical and cheap material for construction and installation work simply can not be found.
Therefore, the appearance of new materials, such as osb plywood, builders and installers are looking with optimism. This is due to the result of the development of advanced technology of composite wood materials. Orientation-chipboard or OSB is a product of natural origin, which is formed by pressing rectangular chips. Plates represent a multilayer sheet with an amount of layers of 4 or more that are glued together with synthetic resins with the addition of wax.
The technology of pressing chips is carried out under conditions of considerable pressure and temperature with the participation of a gluing base - a water-resistant resin. Obtaining a "special wood chip" of osb plywood is promoted by a special technology for chipboard laying. Long chips, up to 140 mm in size and up to 0.6 mm thick, are distributed in the forming carpet with three layers.
The inner layer is the most responsible, responsible for the subsequent strength characteristics of the material. Therefore, in this layer the chips are laid perpendicular to the length of the plate.
Thus, the preservation of useful properties of natural wood and the absence of growth defects and changes in the direction of the fibers take place in the osb or plywood slab. For reference: the OSB plate contains more than 90 percent of the wood.
Properties of OSB plywood
Any building material characterizes consumer properties, as well as opportunities. Among the main properties of OSB can be called:
• Strength
• moisture resistance
• ease of handling
• high fastener retention rate.
According to physical and mechanical properties, the strength of OSB is 2.5 times that of chipboard (chipboard).
The moisture resistance of the material makes it possible to maintain the strength characteristics during the day. The swelling ratio of wood is 10%.
OSB slabs are available for cutting, grinding, planing and drilling, as well as painting and gluing using paints and glues designed for woodworking. Plates are perfectly treated with protective agents - fungicides and biocides.
In comparison with the possibility of coniferous plywood, the coefficient of retention of fasteners for slabs is 25 percent higher.
In addition to the above properties, OSB-plywood is not subjected to spoilage by insects and is the owner of an insignificant level of wood defects.
And if we add to the positive properties a high decorative and aesthetic component with a clearly expressed natural wood structure and a non-waste material application, the advantages of OSB over plywood becomes clear.
The possibilities of using OSB plywood are striking in the ease of installation and accessibility, because the work can be done manually.

Scope of plywood osb
The most active consumers of osb plywood are, undoubtedly, the construction industry, the production of packaging, as well as furniture production. Wood chipboard is considered to be the ideal option for such works:
• roofing and roof covering and its structural elements
• plating of walls of external and internal, rough floors, furniture elements
• construction of temporary fences and closing of openings
• manufacturing and construction of stairs, formwork, crates, scaffolding, racks and shelves.
In each apartment or country house there are several items or elements of interior decoration, made of plywood or OSB plates.
Probably, therefore, the osse plywood, whose price is much lower than the cost of the analogue of plywood, is preferred to use. The ideology of introducing OSB technology "worked" without fail. Plywood osb, the technical characteristics of which are identical to the characteristics of coniferous plywood, make it possible to use cheap raw materials throughout production.
So what are the advantages of using osb plywood when decorating living quarters?
In order to learn how to choose building materials, you need to start by studying the differences between OSB and plywood.
What is the difference between OSB plates and plywood
From the point of view of operational characteristics, to clarify what is better plywood or osb, the latter has proven itself as a better product. The behavior of the plate during operation can be foreseen and predicted, which is impossible to say about the behavior of plywood after intensive exposure to mechanical and atmospheric influences.
The phenomenon of bundle inherent in plywood is absent in OSB. No voids or air pockets emerge from the knots that have suddenly fallen out. A well thought-out binder formulation and perfect pressing technologies tightly press such an opportunity. Moreover, the process of plywood production is technologically and automated. The conformity of the plates to the manufacturer's standard is subjected to rigorous testing for the detection of internal stresses.
A more favorable ratio of strength characteristics and weight provides an optimal possibility of subsequent processing by a standard construction tool. By the way, it's time to remember the elastic modulus for compression, stretching and bending. Plywood osb has the same modulus of elasticity and tensile strength as plywood. Even, oh, happiness! more homogeneous or homogeneous structure, as well as the shear strength of OSB plywood is higher. In this case, the strength characteristics of the plates do not change under the influence of humidity.
It is desirable that the ends of the moisture-resistant plywood osb are reliably protected from the possibility of swelling.
Manufacture of OSB boards is carried out in demanded thickness range from 6 to 38 mm. Therefore, to choose the necessary thickness of the material is easy. Recall that on slabs with a thickness of more than 12 mm, it is possible to make a tongue and groove joint by milling.
