Strand board osb flooring.
Osb sometimes called chipboard is composed of large flat flakes of wood arranged in many layers and sealed together with phenolic resins to make sheets.
Strandboard is a high density substrate which blends practical and creative elements together for a variety of uses in residential and commercial applications.
Oriented strand board osb is a type of engineered wood similar to particle board formed by adding adhesives and then compressing layers of wood strands flakes in specific orientations.
Osb oriented strand board is a different form of sheet material.
In 2001 oriented strand board surpassed plywood in terms of square footage produced.
While the name may be unfamiliar you probably recognize this material.
23 32 cat ps2 10 tongue and groove osb subfloor application as 4 x 8.
Osb when exposed to the weather will eventually swell and bubble up minor instances of bubbling can be sanded but for the most part the osb is irreparable and should be replaced.
It was patented under the name waferboard in 1965 and it quickly claimed a major share of the new construction market being used extensively for sheathing roof decking and subfloors.
Moisture also affects the strength of plywood.
Osb or oriented strand board is an engineered wood product often used as sheathing in walls floors and roofs it is cheaper than plywood and with no internal gaps more rigid.
Osb may have a rough and variegated surface with the individual strips of around 2 5 cm 15 cm 1 0 by 5 9 inches lying unevenly across each.
So while exterior glued plywood can be used outdoors it works best.
First there was plywood and then came oriented strand board osb a less pretty and less expensive but arguably more stable substitute.
Building codes the engineered wood association architects and most builders rate plywood and oriented strand board obs sheathing equal in strength and durability.
Manufacturers of osb often cover it with a water resistant film and add borate compounds to the wood making it toxic to insects like termites and wood boring beetles.
While osb oriented strand board is generally cheaper than plywood it is heavier and not as stiff as plywood and can result in soft squeaky floors under weight the biggest complaint against osb is that it doesn t handle moisture very well so it is more suited for indoor use.
When you need to cover large areas quickly and provide a more rigid floor surface choose tongue groove to give an excellent base for tiles carpet or vinyl.
A viable alternative to plywood this osb board is engineered to prevent any cupping warping or splitting.
Or use square edge.
It was invented by armin elmendorf in california in 1963.
