What thickness plywood should I use for flooring?
The recommended thickness of the plywood subfloor is governed by the spacing of the joists. Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but slightly thicker 3/4-inch plywood should be used for joists spaced further apart.
Is plywood or OSB better for a 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.
Is plywood OK for flooring?
But plywood’s softer surface has a tendency to chip and dent, making the final application of a hard top coating vital to the success of your floor. Plywood floors are suitable for any room where you’d otherwise install hardwood, though kitchens and bathrooms are less desirable since frequent water spills are likely.
Is 18mm plywood OK for flooring?
structural 18 mm ply is fine,you may have to add some timber noggins to offer further support at edges where butting up to chipboard on joists and adjoining edges.
What type of plywood is best 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.
Can you use treated plywood for subfloor?
Use pressure treated wood in any situation where there’s direct contact between the wood and anything that could supply moisture. Subflooring in the kitchen and bathroom may also be pressure treated since water leaks are common in these rooms and subflooring is inaccessible to the residents.
What kind of subfloor do I have?
Subflooring is the structural surface of a floor that supports the finished flooring. The most common types of modern subflooring are plywood or oriented strandboard (OSB), while older homes may have lumber subfloors. A subfloor can also be made of concrete.
Is it OK to use OSB for subfloor?
Most local codes allow OSB to be used for subflooring. It’s always best to check with your local permitting office before using OSB for your subfloor. One advantage that OSB has over plywood is its larger formatting. For plywood, 8-foot and 10-foot long sheets of plywood are standard.
Do plywood floors last?
Plywood Floor Lifespan Although plywood itself is very durable, many other factors come into play when it comes to durability. The plywood can last up to twenty years, sometimes even more. But, if you regularly expose it to water (let alone leave it in the rain), the lifespan can drastically shorten.
Is 12mm plywood OK for flooring?
12mm Plywood The cross-graining technique used in our 12mm ply improves strength, stability and prevents warping, making it excellent for bath panelling, wall lining floors and roofs.
How do I protect my plywood floor?
One way to preserve plywood flooring is to coat it with layers of clear sealant, which will prevent the plywood from becoming damaged by moisture or wear. Sealant can be painted over a plywood floor using tools that are readily available at any hardware store, such as paint rollers.
What thickness plywood should I use for bathroom flooring?
Consider what the top layer of the bathroom flooring will be since some types of plywood are better suited for different flooring. For hardwood, tongue-and-groove CDX plywood rated AC with a 1/2- to 3/4-inch thickness is best. Specifically for subflooring, tongue-and-groove plywood is strong and will reduce squeaks.
Does flooring need structural plywood?
Applications which Require Structural Plywood This includes flooring, wall sheathing and roof sheathing. You will also find structural plywood used in places which may not be specified in the building code, but are still parts of a home’s structure, such as bracing for roofs and floors.
Is 18mm thick enough for flooring?
With the thickness of the floor being at least 18mm, you can be sure it is stable enough to go over joists. Fitting over joists can add extra pressure to your hardwood floor, but structural wood has the correct load bearing properties to cope with this.
