OSB boards

The OSB board- is the Oriented Strand Boards, so the board with the oriented flat scobs. It is a wood- product, flatly-pressed, three-layered board, which consists of rectangular flat scobs, which under the high-pressure and temperatures, with the use as binders of the special waterproof, formaldehyde-phenolic-carbamide-melamine resin, are pressed to boards with a method of the hot rolling . This is the first wood-derivative board, worked out especially for the building.

The board contains over 90% of woods. It is produced from the specially selected trunks of trees – so-called pine leftovers gained mainly from glades of nursing forests. The wood is decoricated and cut completely into the

rectangular flat scobs, which have the assumed dimensions: the length - 100 mm, the thickness - 0, 6 mm and the different width, depending on the part,which they come from.. The strands of scobs in the OSB board run in the topcoats, parallelly to the length of the board , and perpendicularly in the internal layers

High technical parameters of the OSB board get out of maintenances of the wood fibrousness, the adjustement of flat scobs in layers and fitting of long scobs, and by spraying of scobs with the special glue system and the paraffin- emulsion in so-called glue-finishers - it obtains the large weather resistance.
The board is free from humps, cracks and other internal defects , and both surfaces show the similar quality. Produced in the modern technology, it attains plywood- comparable parameters and is relatively cheaper. Easy in the processing and transformation, causes the smaller waste of tools, and thanks to its own large endurance, does not cause problems with fastening of screws and building clamps. The OSB board marks with the stability of the shape, with the very good weather resistance, stroke resistance, with the good sound insulation, easy machinability and processing. The microstructure of fitting scobs prevents breaking off the edges, also at the joining of the edges with nails and gives the high stiffness and the inflexion resistance, as well as on cutting off - these are important properties in the skeletal building.

The use

The OSB board, because of the resistance to the activity of the moisture contracted in the air , low absorbability and the heave, especially is fitted to constructions of buildings in the skeletal technology. It possesses the suitable technical parameters in the range of endurances, guaranteeing the stiffness and the endurance of the building construction. .

The OSB board is wood-derivative material of the future. The quality, the harmlessness to environment, as well during production as boards uses and versatile possibilities of the use are the most important features of OSB boards.

It is perfectly fitted to :

roofing external and internal walls, floors, ceilings, structural elements: girders, double-tee beams and frameworks,

The OSB board can also have the use in other spheres, and namely is used to :

• roofing under bituminous tiles or other roof plating, instead of the traditional shuttering,
• repairs and adaptations
• stairs constructions, landings, outlets,
• boardings of concrete platforms or external stairs,
• temporary fencing of building sites,
• closings of such builder′s openings as door and windows.
• constructions of forwarding boxes and palettes,
• the construction of shelves, stands and exhibition stands,
• skid plates of foam boards,
• furniture- shelves , shop- counters , table- tops , internal window sills,
• strengthenings in upholestery furniture,
• structural elements at the construction of summer-houses and recreational cottages ,
• production of walls in campings, hutment and containers,
• production of rooms on ships and in railway cars (dividing walls, ceilings, etc.)
• panel wainscots.

The OSB board is also the revolutionary step towards of the wooden building. The houses built in the skeletal technology with the use of the OSB board are:

ecological energy-saving cheaper to construct and exploit multi-generation raised in several weeks

The quick building does not mean that these houses are less valuable. Thanks to the advantages of the OSB boards the detached and semi-detached buildings in the skeleton construction, are built more quickly, cheaper, and raised into the precise manner can survive many years. The house in such a construction, holds out strong shocks - it bends, and does not break. If floors, walls and columns of skeletal houses are correctly gasketed, then such houses can be easily and thrifty heated . The coefficient of the heat transmission „k” for the wall executed in the skeletal system depends on the kind and the thickness of the used insulating material. Building of the house with an utilization of the OSB board is 20% cheaper than in the traditional technology. The OSB board will assure the healthy house, user and environment friendly.
