If you are considering starting a building project, you are likely considering whether to use OSB, the popular alternative to plywood that is well accepted by the construction industry.
What does the acronym OSB stand for when talking about building supplies?
- Overly Strong Board
- Oriented Strand Board
- Original Stained Board
When was OSB introduced to the building industry?
- early 1990s
- mid 1980s
- late 1970s
What are the standard thickness size ranges of OSB?
- 0.25 to 0.75 inch
- .5 to 1.0 inch
- 0.67 to 1.25 inch
What is a feature of OSB that makes it attractive to people concerned about our environment?
- OSB is made with recycled wood waste generated by sawmills.
- OSB is made with bark chips generated when pulp mills debark timber before it is made into paper.
- OSB is made with wood from trees that grow quickly with sustainability in mind.
How is OSB manufactured from harvested trees?
- Logs for making OSB are cut into strands, dried and treated with wax and binders.
- Logs for making OSB are sent through an industrial chipper and sprayed with gluing agents.
- Logs for making OSB are turned in a massive lathe that shaves off graduated slats that are glued together.
What process is used to produce finished OSB from treated strands of wood?
- Treated strands of wood are mixed with contact cement in a vat and poured into a form to dry.
- Treated strands are pressed together and then wrapped with Manila paper.
- Treated strands are grouped into big sheets before being subjected to pressure and high temperatures.
Are there any special considerations when deciding on OSB versus plywood for a building project?
- OSB may be used only for interior applications such as floor sheeting.
- Plywood and OSB are interchangeable for most building applications.
- OSB is designed only to be used as sheeting on slanted roofs.
How does OSB rate for strength, durability and life when compared to plywood sheeting of the same dimensions?
- There in no difference between the two.
- Plywood is stronger.
- OSB is stronger.
What is one disadvantage of OSB versus plywood?
- Plywood can be painted easily.
- OSB will swell on any edges exposed to water.
- OSB does not resist moisture well.
What is an additional fact about OSB that may help you decide to build your project with OSB instead of plywood?
- only non-formaldehyde based adhesives used
- superior functionality
- lower cost
