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.
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.
Harmony Series panels manage room acoustics without giving up the look of real wood. Each panel is a layered assembly: hardwood slats form the visible surface, MDF core slats diffuse and dampen sound internally, and a True Black recycled PET felt backing absorbs what passes through.
They are specified for home theaters, recording studios, offices, conference rooms, and open-plan spaces with hard-surface reverberation. Panels align edge to edge for a continuous, uninterrupted surface and install vertically or horizontally, on walls or ceilings.

Tongue and groove boards connect through a tongue on one edge and a matching groove on the other. Shiplap boards use overlapping rabbeted edges. Both can be used for walls, ceilings, and select exterior applications, but they create different joint details.
