Oriented strand board (OSB) has speedily established itself together with time-tested plywood as a staple of the property building market place. OSB is typically manufactured from replenish-able fast growing trees of small diameter, and it is typically produced making use of reduced amounts of hazardous formaldehyde compared to plywood. Therefore, oriented strand board is just as effective and durable for even some of the most challenging commercial and residential construction requirements as it is friendly to nature as well as the natural environment.
Typically, 3 layers of wood strands, combined with a resin of low formaldehyde content, are laid in opposite directions to create OSB, and it is both the strong yet flexible young wood which is used and the way its laid out that provides OSB its distinctive strength. Oriented strand board can be purchased in a number of grades for various uses, and it is generally found precisely where strength and
versatility are key, for example in wall sheathing, roof sheathing and flooring for single and multi-family residences in addition to commercial structures.
Oriented strand board is actually less prone to imperfections when compared with plywood, as it doesn't allow for the open spaces between
ply that often cause problems for plywood of even the highest grade. Manufactured in size-able continuous mats that are cured under intensive heat for additional strength, specialized surfacing can be achieved by oriented strand board makers for specific uses as different as radiant barrier roofing and furniture making. These kinds of mats can be cut to panels of sizes significantly larger than the largest sheets of plywood out there, which adds to the versatility and economy of this innovative, yet already accepted and reliable, wood construction product.
The standards of manufacture for oriented strand board are quite strict, and that is due to the insistence on the use of small dimension trees from managed forests. Such trees provide wood that is tough and consistent; this in turn is the reason why every piece of OSB conforms consistently to its declared technical specification, without the allowances for voids and different sources of timber that are inherent in conventional plywood production, grading and setting of standards. Up to 50 layers of the tough and resilient strands of this renewable and supple young timber are utilized to produce each panel of OSB. With more recent methods of wood treatment and state of the art isocyanate resins guaranteeing much better water resistance and durability, oriented strand board is just as weather proof as even the best plywood plus it is usually considerably lower in cost.
Therefore, more and more residential and commercial builders are turning to Oriented Strand Board for all of their particular wood construction material needs. Eco-friendly as well as favorable to the budget of any builder, oriented strand board is the wood building material into the future, because it is stronger, more consistently reliable and more adaptable than plywood. Research and development is constantly being carried out to further improve upon the properties of oriented strand board, and it is offered by the majority of the most renowned manufacturers in construction material in north America as well as in other major markets. Plainly, oriented strand board will become the new standard in several elements of residential and commercial construction.
