Exterior panels sometimes referred to as RTD sheathing, are designed to hold up to constant moisture. They are completely waterproof and are great for installing in places where you expect consistent exposure to moisture. This RTD sheathing is great for roofs and other outdoor applications.
What is RTD plywood?
RTD plywood is the next generation of plywood made specifically for the construction industry. Specifically, it refers to plywood that has been manufactured using a Resistance Temperature Detector.
What’s the difference between BCX plywood and RTD plywood?
ACX is better (the A side is without knots) than BCX. Plywood is graded with a lettering system A through D, with the letter N sometimes used as well. RTD stands for Resistance Temperature Detectors, a method toe ensure the plywood/adhesive is uniformly heated during bonding of the plies.
Although specialty plywood can have any number of plies above three, most plywood is categorized as 3-ply, 5-ply or multi-ply. 3-ply is one of the most common types of plywood. It is about 2- to 3-millimeters thick and is generally used indoors, since it looks more decorative than thicker plywood boards.
What is BCX plywood used for?
BCX Plywood for Subfloor
One of the most common uses for plywood is for subflooring in new construction homes. Many people want a high-quality and sturdy wooden subfloor that will be able to support weight for the decades to come.

Which plywood is best for roofing?
Most Common Thickness
The most common rafter spacing is 24 inches, and 5/8-inch plywood is recommended for that. It will support roof loads for most situations and is the standard for most roof applications. Roofs with very heavy loads may require 3/4-inch thickness.
What is OSB RTD?
RTD refers to the method used to manufacture the plywood. This is, essentially, next generation CDX plywood which is manufactured with a quality control system using RTDs (Resistance Temperature Detectors) to maintain correct temperature during the bonding process.
Also, as a result of its lower quality, CDX plywood is less expensive than its BCX counterpart. Is BCX Plywood Exterior Grade? Yes, it is. Any ‘X’ stamped plywood can be used on outdoor structures and projects, such as buildings, siding, and even truck-lining.
What does CD stand for in 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 is high quality plywood called?
A-grade plywood: This is the highest-quality plywood and therefore typically the most expensive, since the veneers will be flawless. A-grade plywood is smooth and can be easily painted. B-grade plywood: B-grade plywood is slightly less smooth than A-grade plywood and has a solid foundation.
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.
Plywood is resistant to moisture and does not carry much risk of water damage. Plyboard, on the other hand, retains moisture and is more likely to suffer water damage. Plywood can sag and bend from the center. Plyboard, on the other hand, is less susceptible to bending because it is more stiff than plywood.
Is BCX plywood good for roofing?
Only use CDX plywood for the interior of a house, where water damage is far less likely. Do not use CDX for roofing, sheds, or other places that are exposed to moisture consistently. The sole exception to this is pressure treated CDX, which can survive for decades without even a protective coating.
What is ACX plywood made of?
What is ACX Plywood and How is it Made? ACX plywood is a high-grade plywood made not from a species of tree but from veneers, which are thin sheets of peeled wood grain. Veneers are typically stacked together with each layer’s grain perpendicular to the adjacent two layers.
Can you stain BCX plywood?
Plywood can be stained in many different colors. When building with plywood, you will often want to stain and finish the surface to enhance your project’s beauty. Staining plywood typically requires the use of special gel stains, but by preconditioning the wood you can use any wood stain.
Sheathing: Standard construction plywood used for wall sheathing, roof decking, floor structures (subflooring) and general rough construction where looks and surface imperfections aren’t important. Sanded plywood: General-purpose “project” plywood with decent-looking face veneers that have been sanded smooth.
What is marine grade plywood?
Marine plywood is the highest graded plywood in the plywood industry. The name of these plywood suggests that these are used for the boat construction industry because they are highly resistant to water. Boats require a tremendous resistance to water. Hence, they are made to withstand long exposure to water.
