What is the difference between ACX and CDX plywood?

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.

What is ACX plywood used for?

ACX plywood is ideal for outdoor projects like sheds, which need durable floorboards and outside covering. However, it is also generally great for rooms that are frequently exposed to moisture.

Whats the difference between ACX and CDX plywood?

As such, a sheet of A-C plywood will be very well finished on the face with a relatively unfinished back. Conversely, construction-grade plywood would be C-D (commonly referred to as CDX plywood), which is great for structural use but not suited to be finish material.

What does CDX mean in plywood?

THE LETTERS X

The letter “X” in CDX refers to the type of glue used in the factory to bond the plywood veneers. Some mistakenly think the “X” stands for “exterior”—which is not true. The letter “X” stands for exposure, which means the plywood is tough enough to withstand a little moisture—but for only a short time.

Is ACX plywood exterior grade?

ACX is a designation given to a traditional wood exterior plywood panel with one sanded face and one rough face. It can be used in a wide variety of outdoor projects.

What Is The True Difference Between Oriented Strandboard and CDX Plywood?

What plywood is best for outdoor use?

While similar to standard exterior plywoods, marine plywood is the highest quality (AA, AB, and BB), constructed from wood without knots. Eliminating the knots in wood improves durability because it practically eliminates the possibility of water pockets forming within the wood.

Is CDX plywood exterior grade?

CDX plywood is an exterior grade plywood only in the sense of considering the adhesive used for connecting the veneer plys. The wood isn't pressure treated or treated in any other way to make it waterproof, unless it is marked as being “pressure treated” plywood.

Which is better OSB or CDX plywood?

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.

Can CDX plywood be used for roofing?

CDX Plywood

Plywood gets it strength from multiple layers of wood bonded together. The wood grain alternates from layer to layer, adding significantly to the strength of the plywood sheet. A special grade of plywood called “CDX” is a popular choice for roof sheathing.

Is CDX plywood strong?

X stands for exposure, which is the type of glue used to bind the plywood together. However, note that the grading is not about the quality but the appearance of the wood because CDX is pretty strong and resistant to damage.

What is the best plywood to use for roofing?

CDX plywood is considered the best roof sheathing material because of its better dimensional stability. That means it's hardly waterproof and readily absorbs water, but it also sheds the water quickly and reverts to its original shape and thickness effortlessly.

Does CDX plywood have exterior glue?

Why is CDX cheaper than OSB?

Oriented strand board (OSB) combines wood chips, glue, and resin into the shape of a sheet of plywood and bakes them together. What is this? It is often less expensive than CDX plywood because this manufacturing process doesn't require the same costly veneers found on the front and back of CDX plywood.

Is CDX plywood water proof?

Keep in mind that this kind of plywood is water resistant, not waterproof, and can still be ruined from a leaking tub or toilet. CDX plywood is often used under shingles and roofing felt, on walls (just behind the siding and insulation), and as a sub floor just under the carpet pad or a tiled floor's durock.

Can I use CDX plywood as siding?

Allow panels to dry properly prior to installation. All wood will expand and contract so always leave a 1/8” gap between all joints and seams to accommodate swelling with varying moisture conditions. In any case, I cannot recommend using CDX plywood of any sort as siding.
