Tongue and groove flooring was developed in the late 1800’s when flooring manufacturers began producing planks with interlocking edges as a way to make hardwood flooring that eliminated the need for exposed nail heads while creating a smooth, level surface. This material is available in solid and engineered hardwood and is commonly called T & G flooring.
Many homeowners consider using tongue and groove to be the best way to create a perfect hardwood floor, whether you DIY or hire a pro.
What is Tongue and Groove Hardwood Flooring?
Tongue and groove planks have a protruding ridge or “tongue” on one side and a concave slot or receiving “groove” on the opposite side. During installation the tongue of one board fits into the groove of the next. The ends of the boards also have a tongue and a groove.
Tongue and groove creates a tight, solid seam while allowing some movement between the separate boards so that the wood flood can expand and contract with humidity and temperature changes.
Tongue and groove flooring is relatively easy to install because the tongue will fit securely into the groove on the adjoining board.
Types of Tongue and Groove Hardwood Flooring
Engineered T&G Flooring Solid Hardwood T&G Flooring
There are two different types of tongue and groove flooring – solid hardwood and engineered hardwood. Both of these types of flooring come in nearly endless varieties of color, texture, and grain.
Solid Hardwood T&G Flooring
Solid hardwood flooring is made from a single solid piece of hardwood. Solid hardwood is durable, easy to maintain, and can be sanded and refinished several times.
Engineered T&G Flooring
Engineered hardwood is made with a real hardwood top layer or veneer, a piece of wood on the bottom, and a highly stable core in the middle. The core consists of 5 or more layers of plywood pressed and glued together in a crisscross pattern. This type of construction makes engineered hardwood less likely to expand and contract with temperature and humidity. Most engineered hardwood flooring can be refinished at least once depending on the thickness of the top layer.
Buying Tip: Another advantage of engineered hardwood flooring is that it can be installed in areas of higher humidity such as a bathroom or below grade. Check with the manufacturer to make sure it is designed for your specific use.
