FAQs

Is a tongue and groove subfloor worth it? ›

Increased Strength and Rigidity

The interlocking design of tongue and groove plywood enhances the overall strength and rigidity of the subfloor. When properly installed, the interconnected panels distribute weight more evenly across the entire floor surface, reducing the likelihood of weak spots or structural failures.

Know More ›

Is OSB or plywood better for subfloors? ›

Because of its inherent stiffness and rigidity, plywood is a better choice for flooring under ceramic or stone tile. While a well-built subfloor should endure the lifetime of the house, OSB is more flexible than plywood, making it unsuitable for use under heavier flooring such as ceramic or stone tile.

Do you stagger tongue and groove subfloor? ›

By staggering you have cut the number of potentially weak corners by 50%. Non-staggered joints will not result in the immediate, or even long-term, self destruction of your flooring because: Tongue and groove subfloor also means that subfloors are stronger than ever.

Does tongue and groove subfloor need blocking? ›

Tongue-and-groove plywood is actually more effective than solid blocking at preventing squeaks, because over time the blocking will shrink, leaving unsupported edges.

Does tongue and groove need underlayment? ›

Don't Skip Out On the Underlayment

As a floating floor, tongue and groove flooring does not need to be attached to the subfloor. However, if you don't add an underlayment between the subfloor and the panels, you can run into several problems. Most notably, your floor will squeak and bend as you walk across it.

Know More ›

Should I use tongue and groove for flooring? ›

Long-Lasting Quality. The tongue and groove method creates a seamless lock between planks. As we mentioned above, tongue and groove flooring can be refinished numerous times (lasting for decades), and even engineered hardwood flooring can be sanded and refinished up to two times!

Is tongue and groove better than plywood? ›

Each sheet has a protruding tongue on one long edge and a corresponding groove on the opposite long edge. This design creates a tight and secure connection when the sheets are joined together, resulting in a strong and stable surface. Tongue and groove plywood excels over standard plywood for floor decks.

Know More ›

Is tongue and groove worth it? ›

Pros And Cons Of Tongue And Groove

Tongue and groove also tends to be stronger. As opposed to boards laid on top of one another, interlocking boards create more friction and surface area, which prevents movement and strengthens the paneling. However, it's not as watertight as shiplap.

What is the best subfloor to use? ›

Both plywood and OSB are effective choices for your subfloor needs, but OSB may be a better option for a garage than plywood. Plywood is a better option for projects that require a lot of cutting and molding, while OSB is a good option for those who need to cover areas where moisture exposure may be an issue.
