Tongue-and-Groove

Definition

Tongue-and-groove (T&G) is a type of lumber, metal, or precast concrete having matching or mated edges to provide a tight fit.

Purpose

The purpose of tongue-and-groove construction is to create a strong, tight, and seamless joint between boards or panels, enhancing structural stability and aesthetic appeal.

Examples of Use

1. Flooring: T&G boards are commonly used in wood flooring to create a smooth and stable surface.
2. Paneling: Interior and exterior wall paneling often uses T&G boards for a tight fit and attractive finish.
3. Decking: T&G boards are used in decking to ensure a durable and weather-resistant surface.
