It’s common to look for moisture performance, strength and fastener-holding power when choosing subflooring. But there’s one other quality that should be factored in: a secure-fitting tongue and groove profile. Chris Vegas, technology manager for Huber Engineered Woods, discusses why an “easy fit” may not be a squeak-reducing, secure fit. Read below to learn how a secure-fitting tongue and groove profile can help create a quiet, stiff floor.
What’s the main function of the tongue and groove profile on subflooring panels?
The purpose behind a tongue and groove profile is edge support. It may seem like a small detail, but the way the edges of a panel are manufactured not only affects how the panels lock together during installation, but it also affects the long-term performance of the subflooring system. While some panels claim to provide an easier fit, it’s important to make sure panels have a snug-fitting tongue and groove to reduce the chance for deflection — the up-and-down movement that can lead to squeaks.
What are the different types of tongue and groove profiles?
Many traditional OSB and plywood panels have a wedge-shaped tongue that may allow panels to go together easily but can limit the amount of edge support provided. When using this kind of panel, consider using a subfloor adhesive that will fill the gaps within the tongue and groove connection to create firmer support at this vulnerable joint where movement leading to squeaks can occur.
Premium engineered wood panels such as AdvanTech® subflooring have a tongue and groove profile that is shaped to fit snugly like a puzzle piece within a uniquely shaped groove. This helps provide more consistent edge support at this connection. While this secure fit profile provides resistance against deflection that can lead to squeaks, part of the proprietary design of the tongue and groove profile of AdvanTech® panels is the inclusion of a self-spacer. Wood products by nature will expand and contract due to moisture content. Next time you select a subfloor product, make sure not to overlook the edge support and built-in spacing design of the tongue and groove profile. Reducing movement at this critical joint helps prevent squeaks and pops for a quiet floor and happy homeowners.
