Oriented strand board Oriented strand board (OSB), also known as sterling board, sterling OSB, aspenite, and smartply in British English, is an engineered wood particle board formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations.t was invented by Armin Elmendorf, California US in 1963 OSB Patent. OSB may have a rough and variegated surface with the individual strips of around 2.5 × 15 cm (1 × 6), lying unevenly across each other and comes in a variety of types and thicknesses.

- OSB boasts a more consistent density. While a sheet of plywood might be 5 to 7 plies thick, a sheet of OSB is made from as many as 50 strand layers packed and compressed into the same thickness. There's no equivalent of the weak spots that can be left in plywood when knotholes in adjacent plies overlap.

Osteoblast Osteoblast (from the Greek combining forms for  bone , ὀστέο-, osteo-and βλαστάνω, blastanō germinate) are cells with single nuclei that synthesize bone.steoblasts are the major cellular component of bone. The functional part of bone, the bone matrix, is entirely extracellular (outside of the cells). The bone matrix consists of protein and mineral. The protein is called the organic matrix; it is synthesized first, and then the mineral is added.

Plywood or OSB Panels: Which is better? Building codes consider OSB (Oriented Strand Board) and plywood interchangeable and refer to both as “structural wood panels” as both OSB and plywood panels are created when wood is glued and compressed to form a rigid panel. Despite the obvious similarities, there are some essential differences.here are approximately 50 layers of wood strands in every OSB panel. While the two kinds of panels carry the same span rating (because they are based on strength and not thickness), nail pull and screw hold, OSB panels have several structural advantages over plywood panels:

OSB ...slick side in/out & up/down? Re: OSB ...slick side in/out &amp; up/down? If you want to know why physically one side is rough and the other side is smooth - it originates in the manufacturing process. Strands are deposited on screens in the forming or orienting process (hence oriented strand board).
