What does CDX mean with plywood?
What is CDX? 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.
What’s the difference between CD and CDX plywood?
CDX sheathing is used primarily by contractors to build exterior walls and roofs. The letters “CD” represent the veneer grades used on the front and back, and “X” means the glue (not the wood) is rated for outdoor exposure—but only for a short time.
What means CDX?
The Credit Default Swap Index (CDX) is a benchmark index that tracks a basket of U.S. and emerging market single-issuer credit default swaps. Credit default swaps act like insurance policies in the financial world, offering a buyer protection in the case of a borrower’s default.
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 exterior grade plywood?
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.
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. The APA would recognize CDX Grade Plywood as C-D Exposure 1 plywood.
Is CDX plywood waterproof?
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.
How can you tell if plywood is outdoor grade?
Exterior plywood is marked with an X to denote this use and the construction grade is in the first two letters; the first letter refers to the front of the plywood and the second refers to the back. A is a premium grade that can be used on cabinetry or other higher-end uses where appearance is crucial.
What are the 5 grades of plywood?
Typical plywood grades and characteristics “A” Grade. Sanded smooth, paintable. “B” Grade. Solid surface with some repairs, usually football-shaped patches and/or wood filler. “C” Grade. Tight knots to 1-1/2 in. “D” Grade. Knots and knotholes up to 2-1/2 in.
What is OSB good for?
OSB is now used for about 70 percent of all floor, wall and roof sheathing in North America. Some panels have a textured surface, which makes them less slippery when used for roof sheathing. OSB panels often have lines at 16- and 24-in. intervals so you know where underlying studs, rafters and joists are for nailing.
What is BCX plywood used for?
BCX Sanded Plywood Project Panel. BCX plywood for projects such as shelving, paneling, stairs, exterior wall sheathing, soffits, a base for siding materials, the support structure for cabinets and other built-ins and more.
What is OSB used for?
Applications. OSB is extensively used for wall sheathing, floor underlayment, roof cover and I-joist in both commercial and residential building. OSB also is used in furniture, reels, trailer liners and recreational vehicle floors. Figure 3 shows siding and I-joist application of OSB in building construction.
Can I use CDX for subfloor?
OSB and CDX subfloors come in tongue and groove. It’s ideal for subflooring, because it prevents the edges of the plywood from moving and squeaking after insulation. Construction adhesive is used to better seal the tongue-and-groove joint.
What is the best wood to use on a roof?
Builders love plywood for its water resistance, structural stability and low cost. They also love oriented strand board, though. It costs even less and is comparable to plywood on the other two counts, and they increasingly prefer OSB for roof sheathing. Either is an acceptable choice in most jurisdictions.
What is the best roof sheathing?
OSB is now the most-used sheathing and subflooring material for new roofs and roof replacements. OSB is currently selling for less than plywood by approximately $3 per sheet, meaning a savings of several hundred dollars per conventional home.
Is CDX plywood strong?
CDX is a type of plywood. 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.
Can you paint CDX plywood?
CDX plywood has one smooth side and one rough side. Although it is constructed from waterproof glue, it still needs painting if used outside. CDX plywood displays an array of grain direction and imperfections that must be covered.
How long will CDX plywood last?
Exposure 1 panels have a fully waterproof bond and are designed for applications having temporary exposure to weather such as where construction delays may be expected prior to providing protection. It is not uncommon for panels to be exposed to weather for six months to a year. Also, can you use CDX plywood outside?.
Does CDX plywood rot?
After all, because of the composition of wood grain that is used during CDX plywood production, this type of plywood is able to absorb moisture at a certain level without warping, splitting, or rotting.
What is the cost of CDX plywood?
Construction Grade Plywood Thickness Type Price 15/32″ CDX $28.97 23/32″ CDX $35.97.
What is the difference between CDX and pressure treated plywood?
Pressure-treated plywood: This type of plywood is highly resistant to mold and mildew, as it is saturated with chemicals. CDX sheathing: An inexpensive type of plywood, CDX sheathing should never be left uncovered. It’s usually covered with bricks or shingles for roofs, garages, or storage bins.
