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.

WindsorONE WORS6 Reversible Shiplap Board
WindsorONE WORS6 Reversible Shiplap brings clean shadow lines and classic interior character to walls, ceilings, and wainscoting. With a smooth face on one side and a rough-sawn face on the other, it gives you two finish styles in one primed board.
Merchandising description
For customers who want a premium interior shiplap look, WORS6 offers flexibility without sacrificing consistency. WindsorONE positions this profile for timeless interiors ranging from modern farmhouse to coastal cottage and classic craftsman styling, while the reversible faces make it easy to match the project’s design direction.
The board comes factory primed with a three-coat acrylic latex primer, which supports a smooth painted finish, and WindsorONE highlights its straight, tight, and true construction for easier installation. Because it is a reversible shiplap board, installers can choose their own gap appearance rather than being locked into a preset reveal.
