What is best plywood for subfloor?

While OSB is the most popular structural panel, CDX plywood is the most popular type of traditional or "veneer" plywood. CDX plywood is like other laminate plywoods, but the outer layers of laminate are grades "C" and "D," which means they are cosmetically rough and contain many imperfections, thus lowering their cost.


Likewise, people ask, what is the best material for subfloor?

Plywood has been a standard subfloor material since the 1950s and remains the preferred subflooring for many builders. Standard plywood can be used for subfloors, but a better material is 3/4-inch tongue-and-groove plywood subflooring.

Beside above, what is the best plywood to use for flooring? Interior plywood is ideal for rooms not exposed to moisture, such as bedrooms, and makes a good subfloor for carpeting, tiles, vinyl, engineered wood laminate flooring and hardwood flooring. Exterior plywood is a better choice for bathrooms, kitchens and any other rooms exposed to water and moisture.

Just so, what is better for subfloor OSB or plywood?

The National Tile Contractors Association and the Resilient Floor Covering Institute both recommend plywood for subflooring and underlayment, because it doesn't have the risk of swollen edges that OSB does. Plywood also has a slight advantage in stiffness, which means that subflooring panels need not be quite as thick.

Can you use treated plywood for subfloor?

Kiln-Dried-After-Treatment Agreed. Under the IRC this 19% or less moisture content lumber is called kiln-dried-after-treatment lumber and is perfectly acceptable to be used in structural sheathing, subflooring, or framing.
