Key Takeaways
Is CDX or OSB better?
Although some people will ultimately choose CDX, many experts argue that OSB is better overall for roofing. OSB is far less likely to expand and contract when exposed to humidity and moisture, even though it will take longer to dry. With wrapping, though, it can withstand the elements without issue.
Is CDX as strong as plywood?
The less the number of knots, holes and repaired defects the more expensive the plywood. If so, it therefore, means CDX has the most number of knots and defects, making it a lower grade plywood. C in CDX means one side of the plywood is of grade C, and the other is of grade D.
Is CDX the same as plywood?
CDX is veneer plywood, which is manufactured by gluing and pressing together sheets of wood. The letters C and D represent the grades of either side of the plywood, while X stands for exposure.
Is CDX waterproof?

Is OSB as strong as CDX?
OSB is made using small wood chips or wood flakes that are then glued together. On the other hand, CDX is a type of plywood that uses very long and thin wooden veneers that are oriented in a cross-grain pattern. This, therefore, means that CDX plywood is quite a bit stronger than OSB
Is OSB cheaper than CDX?
If you are big on saving, then you would want to go with OSB since it is a cheaper version of CDX. However, in as much as CDX is more expensive in relation to OSB, generally, they are both affordable and easily available in lumberyards and stores.

Is OSB board stronger than plywood?
Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists. However, nail-holding ability controls performance in shear wall applications.
What are the disadvantages of OSB?
If you are big on saving, then you would want to go with OSB since it is a cheaper version of CDX. However, in as much as CDX is more expensive in relation to OSB, generally, they are both affordable and easily available in lumberyards and stores.
