Looking for siding that’s stylish, strong, and stands the test of time? Tongue and groove siding has been a go-to for generations — and for good reason. In this guide, we’ll break down everything you need to know before choosing this classic yet modern cladding solution.

What is Tongue and Groove Siding?
Tongue and groove siding consists of interlocking boards designed to fit seamlessly together. Each board has a “tongue” on one edge and a “groove” on the other, ensuring a tight seal that protects against wind, moisture, and other elements. This design not only enhances durability but also creates a smooth, polished look for both interior and exterior applications.
