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.
How thick should plywood subfloor be?
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.
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.
What is the best wood to use for subfloor?
Plywood is considered the most popular material used for subflooring, it has been used since the 1950s and remains one of the top choices for contractors. Standard plywood works perfectly fine as a subflooring material, but the best option is ¾” tongue-and-groove plywood subflooring.
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.
Can I use plywood for subfloor?
Standard plywood can be used for subfloors, but it is more common to use tongue-and-groove sheets that interlock along the edges. The recommended thickness of the plywood subfloor is governed by the spacing of the joists. The type of OSB used for subfloors generally is made with tongue-and-groove edges (T & G).
Do you 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.
Should you lay plywood over plank subfloor?
Take time to make sure your existing planks are well secured in place. Repair any broken planks. Install a layer of at least ½” or preferably 5/8” ply over the existing planks. Like all wooden flooring products, it’s a good idea to acclimatise your plywood before laying it.
Do you have to use tongue and groove plywood 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.
Is pine plywood good for subfloor?
In many older houses, the pine subfloor was the only floor and it held up well. Uncovered pine subflooring appeals to recycling enthusiasts as well as fans of distressed wood. Drawbacks include a thinner, less-insulated floor and a less-durable surface than other flooring types.
What is the strongest plywood?
If you ever wondered “what is the strongest plywood?” The answer is Marine plywood. It is the strongest and toughest of all plywood on the market. It is bonded with high-quality glues to make the plies structurally solid and resistant to moisture.
What is the difference between subfloor and underlayment?
Basically, subfloors are a structural part of your home that provide strength and rigidity to your home’s flooring. Underlays, on the other hand, protect your floor covering from moisture, help soundproof your floor, and offer cushioning and comfort underfoot.
