OSB, or Oriented Strand Board has become the utility sheathing of choice. Commonly used in construction of homes, garages, sheds and commercial structures, OSB offers a very affordable material that is strong, easily cut and structurally superior at a very affordable price. OSB is made from a completely renewable resource -- small-diameter, fast-growing trees, so itís forest friendly. It's use started in the Ď70ís and since the early Ď90ís, OSB has become the standard for sheathing in todayís home building.
John's Lumber stocks OSB in 4x8 and 4x9 sheets 7/16" thick, 4x8 1/2" and 5/8" thick and a 4x8, 3/4" thick, tongue and groove used for flooring underlayment.
- When compared by weight, wood is used more than all plastics, metals, and concrete combined.
- Unlike steel or concrete, OSB is made from a completely renewable resource -- small-diameter, fast-growing trees.
- Pound for pound, wood is stronger than steel because it has a more favorable strength-to-weight ratio.
- In 1980, North American OSB panel production was 751 million square feet (3/8" basis) (0.7 million cubic meters). By 1990, this figure was 7.6 billion square feet (7.0 million cubic meters). In 2005, this figure had grown to 25.0 billion square feet (22.1 million cubic meters) - that's enough to circle the earth 46 times.
- Since the 1990's OSB has proven to be an economical and competitive structural panel.
