WHAT IS TONGUE & GROOVE CONSTRUCTION?
Tongue and groove is the type of joint construction on wood flooring planks that allow them to easily fit together. One side of the plank has a projection called the tongue while the other side has a groove to match. The panels are laid flat with each tongue fitting into the groove next to it. This allows the planks to interlock seamlessly across the floor. Tongue and groove flooring can be installed in either a glue down, nail down or floating method. If floating tongue and groove, a seam glue is used to adhere the tongue and groove together.
