Choosing the right tongue and groove cedar for ceilings, walls, and soffits — profiles, grades, and installation.

Tongue & Groove Cedar Buying Guide

Tongue and groove (T&G) cedar is a versatile profile used for ceilings, walls, soffits, and feature installations. The interlocking profile creates a clean, uniform appearance with no visible gaps.

Common Applications

  • Interior ceilings and feature walls
  • Exterior soffits and porch ceilings
  • Sauna lining
  • Accent paneling

Profiles

T&G cedar is available in 1x4, 1x6, and 1x8 widths. The most common choice is 1x6 for a balanced appearance. Narrower profiles (1x4) create more visual texture, while wider profiles (1x8) create a cleaner look.

Grades

  • Clear Cedar — ideal for visible applications where appearance matters
  • Select Tight Knot (STK) — good value for general-purpose installations

Installation

T&G cedar installs with concealed nailing through the groove. The interlocking profile keeps boards aligned and eliminates gaps. Plan your layout to minimize waste and ensure board ends land on joists or studs.
