Tongue-and-groove Planks in Wood Flooring Installations

What is Tongue-and-Groove and how does it work?

"Tongue-and-Groove" is a method of joining two pieces of wood together, commonly used in wood flooring. This design involves milling each wood plank with a protruding edge (the tongue) on one side and a corresponding groove on the opposite side. The tongue of one plank fits snugly into the concave (the groove) of the adjacent plank, creating a tight, interlocking connection and also the system holds the boards together securely without the need for visible nails or fasteners on the surface.

Which type of Wood Flooring is suitable for Tongue & Groove installation?

Tongue-and-groove (T&G) installation is a versatile method suitable for various types of wood flooring, as it ensures a tight and secure fit. Below is a description of the types of wood flooring where T&G installation is most appropriate:

Solid Hardwood Flooring

T&G is an excellent choice for solid hardwood flooring, which consists of planks made from a single piece of natural wood. The interlocking edges provide the stability needed for this type of flooring, especially since solid wood expands and contracts with changes in humidity. Solid hardwood planks are typically nailed or glued down using the T&G system.

Engineered Wood Flooring

Engineered wood flooring, made from multiple layers of wood with a hardwood veneer on top, is highly compatible with T&G. Its dimensional stability makes it less prone to warping, making T&G installation effective. Engineered wood can be nailed, glued, or floated, offering flexibility in installation methods.

Bamboo Flooring

Both solid bamboo and engineered bamboo flooring often feature T&G edges. T&G installation is suitable for bamboo flooring as it provides a snug and secure fit. Depending on the type, bamboo flooring can be nailed, glued, or floated during installation.

Parquet Flooring

Parquet flooring, whether made from solid wood or engineered wood, commonly features T&G edges. This is essential for ensuring precise alignment of the intricate patterns (e.g., herringbone or chevron). T&G parquet flooring is typically glued down for added stability.

Summary for Tongue-and-Groove

Tongue-and-Groove is best for homeowners seeking a secure, durable, and visually seamless flooring option that can adapt to various materials and environments. The installation and maintenance requires more effort and expertise compared to some modern alternatives, such as click-lock systems.
