What kind of plywood do you 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.
What is the thinnest plywood I can use 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.
What size plywood is best for subfloor?
The spacing of the joists governs the recommended thickness of the plywood subfloor. Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but you should use slightly thicker 3/4-inch plywood for joists spaced further apart.
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. But to start off, we will need to remove the tongue so the plywood is tight with the exterior ICF walls.
Is it better to use OSB or plywood for subfloor?
OSB has a lower resale value than plywood due to its lower strength. For this reason, few homeowners prefer OSB in their homes. Apart from costs, plywood is superior in all the other areas, such as the strength of the structure. For this reason, it’s a superior material for use on the subfloor.
Is OSB better than plywood?
Wood fiber is used more efficiently in osb. Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists.
Can OSB be used as subfloor?
OSB Subflooring. OSB subfloor serves as a base under the finish floor (hardwood, engineered wood, vinyl tile, etc.) and even below the underlayment, in some cases. Plywood has long been used for subflooring.
Does it matter which way you lay plywood?
It is usually correct to lay sheet material across the direction of the joists, this ensures even distribution of loading on joists, however, plywood is cross laminated so each layer is of different direction providing a strong floor covering.
Can cement board be used as subfloor?
No, Hardie cement board is not meant to be structural, and it will not work in place of a subfloor. The board is very strong in compression and very stable so that the tiles applied to it do not crack, but it has very little shear strength.
Can I use plywood sheathing for subfloor?
Like Sturd-I-Floor, Rated Sheathing may be plywood or OSB. When used as a subfloor, Rated Sheathing typically requires installation of an additional layer of underlayment on top of it before finish flooring can be applied. The underlayment requirements vary depending on the finish flooring.
How many layers of plywood do you need for a subfloor?
Whenever you use two layers of material to build up to the required minimum thickness of subfloor they both need to be nailed to the joists.
What type of plywood should be used under hardwood flooring?
Hardwood flooring: Plywood is the best subfloor for hardwood flooring installation. CDX plywood ranging from 1/2 to 3/4-inch-thick and rated A/C will serve well for any hardwood flooring installation. Tongue-and-groove plywood is available to reduce squeaks and help the subfloor fit together better.
What goes on top of subfloor?
Underlayment: Some types of flooring can be installed directly on top of the subfloor, such as vinyl flooring. Other types need a middle layer, called underlayment, such as laminate,carpet and tile.
Do you nail or screw subfloor?
Ideally, nail down your subfloor using corrosion-resistant nails that will securely hold it in place and last a long time. Screws are a great alternative that you can easily remove, but they are not as sturdy. Screws are superior in terms of reducing floor squeaks, but the installation is slower.
Do I need to glue plywood to subfloor?
The answer: Glue. Although using a subfloor adhesive (or subfloor glue) is not required by code, it is a standard practice that can help prevent floor squeaks by reducing the chance for movement at the panel-to-joist connection. A quality subfloor adhesive will also increase the overall stiffness of the floor.
How do you secure plywood subfloor?
Quote from the video:
Quote from Youtube video: Because if you pound your underlayment down with nails you're going to be leaving big dips in the floor i'll show you that in a few minutes.
Should you staple or screw underlayment to subfloor?
Never use adhesive on the sub-floor to attach the plywood underlayment. Instead, fasten the plywood underlayment panels with staples, ring-shank nails or screws.
Do you stagger plywood flooring?
More plywood sheets are nailed down, staggering seams for a stronger fit. When you build, you always stagger. It’s what makes a pile of boards and materials into a solid structure. Stagger stagger.
