Flooring finish

Definition of Baseboard

A baseboard is a narrow piece of wood, MDF, vinyl, or any other material that’s used to cover the gap between the bottom of a wall and the floor

It usually protects the wall from damage and ties into a home’s overall design.

Furthermore, baseboard moldings can serve as a transition point between two flooring materials, such as carpet and tile. They can also be used to hide cables and wires around a home.

Baseboards are usually between 3 and 8 inches in height and 2.5 to 6 inches thick.

The material you choose depends on the application. For example, baseboards in commercial settings must meet specific fire and safety codes.
