What is CDX plywood good for?
CDX Plywood is used primarily by contractors to build exterior walls and roofs. CDX plywood has one side veneer grade “C” and one side veneer grade “D”. The two are bonded together with glue which can withstand a little moisture.
What is the difference between CDX and plywood?
CDX is a type of plywood. Basically, plywoods are thin veneer sheets that are glued and held together with linking plies. 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.
Which is better OSB or CDX plywood?
CDX and OSB are used for almost similar things, but because they have different features, one is better applied in some tasks and the other one on other tasks. CDX is best for sub-flooring. OSB also seems to be good for roof sheathing. But take care, it also requires that you use water-resistant coating at the edges.
Is CDX plywood waterproof?
When it comes to CDX plywood, the ‘X’ signifies exposure, which means that while CDX plywood is slightly water-resistant, it is not waterproof, and therefore the CDX plywood can only withstand a limited amount of moisture over a short period of time before showing signs of degradation.
Which plywood is waterproof?
CDX is made of rough, lower-quality wood that is heavily treated for water resistance and is ideal for things like roof sheathing. Marine-grade plywood is much smoother and higher quality and has the best waterproofing of any plywood.
Does CDX plywood have Formaldehyde?
Phenolic formaldehyde glue is one of the formaldehyde based family of adhesives commonly used in the production of pressed wood products. It is primarily used as the glue in structural external rated softwood plywood panels such as CDX.
Is ACX stronger than CDX?
Since ACX plywood is a higher grade material than say CDX plywood, it is specifically used in cases that require good appearance or a smooth finish, along with durability. Because this plywood is more expensive than other grades of softwood plywood, it is only used where needed, not in all situations.
Can you use CDX plywood for subfloor?
When placed across equally spaced beams, joists or rafters, CDX is almost 10% stronger than OSB, the other alternative which is often utilized as a subfloor due to its economy. This additional strength really helps when using CDX plywood as subfloors. This added strength means less bowing/flexing in the subfloor.
Is CDX plywood rated for outdoor use?
CDX plywood, a stock item at most lumberyards, is a utility grade suitable for most outdoor projects.
Is OSB stronger than plywood?
Wood fiber is used more efficiently in osb. 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.
Should I use OSB or plywood for roof?
OSB takes longer than plywood to get saturated, but also takes much longer to dry out. When used as roof sheathing, this tendency to hold moisture means it will degrade faster than plywood when exposed to chronic leaks.
Is OSB more water resistant than plywood?
OSB takes longer to get wet than plywood but also takes longer to dry out. Manufacturers insist that OSB’s moisture problems have been corrected, thanks to the development of water-resistant edge seals. But of course that edge seal is lost when panels get cut on site, as they often do.

How long will CDX plywood last outside?
How Long Will Exterior Graded Plywood Last Outside? Pressure treated exterior graded plywood can last roughly 20 years – even in rainy and/or humid climates. But this is only if the plywood has been properly sealed (especially along those tricky exposed sides).
What can I put on plywood to make it waterproof?
Liquid Latex Spray – on or paint – on Latex is another effective plywood protector. It’s available at hardware stores and forms a waterproof layer on the surface of the plywood to protect it from moisture. Liquid Latex products are easy to apply and relatively inexpensive.
