Tongue & Groove
Tongue and groove wood offers a clean, continuous look for walls, ceilings, siding, and other architectural applications. At Mason’s Mill & Lumber, we offer a variety of wood species, profiles, and finishes for both interior and exterior projects.
What Is Tongue & Groove Wood?
Tongue and groove, commonly referred to as T&G, is a milling profile that allows adjoining boards to fit together using a tongue on one edge and a matching groove on the other.
This connection creates a consistent surface with clean lines and a uniform appearance. Depending on the profile and wood species, tongue and groove can complement traditional, rustic, or modern architectural styles.
From traditional Southern Yellow Pine to thermally modified hardwoods and softwoods, our team can help you find the right material for your project.
