What size plywood is best for subfloor?

The minimum thickness of plywood for subflooring is about 5/8 inch. Since it does not hold fasteners as well as plywood, OSB must be a little thicker, or at least 23/32 inch. There are several factors that determine what subfloor thickness is optimal for added benefits like insulation.

What type of plywood is used for roof decking?

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.

How thick should roofing plywood be?

3/8 inch
Most roofs will be sheathed in plywood at least 3/8 inch thick. That will suffice on a roof with rafters set 16 inches apart with minimal roof loads. Loads will vary with the pitch of the roof; the flatter the roof, the greater the load on any one section. Steeper roofs will have lighter loads per square foot.

Is it better to use OSB or plywood for subfloor?

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.

Which is stronger OSB or plywood?

OSB and plywood offer similar (and sufficient) performance in terms of strength and functionality, though plywood is about 7% stronger. … Plywood will absorb moisture quicker than OSB, but consequently it will also dry quicker.

What type of plywood should I use for subfloor?

Standard plywood can be used for subfloors, but a better material is 3/4-inch tongue-and-groove plywood subflooring. The tongue-and-groove edges interlock to resist movement along the panel edges and create an overall stiffer floor.

Is it better to nail or screw subfloor?

Using code-approved screws rather than nails is the best option for avoiding movement. If using nails for subfloor installation, stick with ring-shank nails; smooth nails may withdraw easier, leading to squeaks.

Do you need tongue and groove for subfloor?

For subflooring, you use tongue and groove plywood. The tongue and groove are only along the 8 foot edges. On the four foot edges, your seams will fall on joist tops, so no need for tongue and groove.

How many layers of plywood do you need for a subfloor?

Actually you need 1 1/4 thick plywood for a subfloor but if you support it on one foot centers it will be strong enough for a good subfloor. If you don’t have it supported properly you will get break in you mortar or tiles you can’t have the movement in the subfloor for tiles .

What goes on top of a subfloor?

Underlayment

The underlayment material is installed below the floor covering and placed on top of a sub-floor. Under the visible covering, there is a layer made of soft or foam-like materials with a thickness of between 1/4- or 1/2-inch. … Some common choices include; foam, hardboard, cork, plywood, and cement board.

Does plywood subfloor need to acclimate?

The plywood underlayment should be moisture tested to be sure it is no more than 4% variance to the flooring. You’re making the same assumption many make, that wood will “acclimate” in a certain amount of time. Fact is, it’s all about moisture content.

Which way do you lay plywood subfloor?

Do I need 2 layers of subfloor?

Almost no one puts down double-thick subfloor in residential applications (for cost and handling reasons), and both layers need to be fastened to joists. Only thin underlayment can be fastened just to the subfloor.

Can you put a new subfloor over old subfloor?

One of the benefits of removing the old flooring is it allows you the chance to fix any loose subflooring or squeaks by re-securing the main subfloor to the floor joists prior to installing the new flooring. With all that being said though the answer is YES you can install New Wood Flooring over the old.

What is under subflooring?

A subfloor is the solid material beneath your floor covering. … In areas that are below grade, such as a basement, the concrete foundation is often considered the subfloor, though plywood and OSB panels can be installed over concrete using ground-level floor joists called sleepers.
