1. What is a Tongue and Groove? (Woodworking Joint)
A tongue and groove joint is a type of woodworking joint that simplifies the installation process of wood boards and materials. Its main purpose is to easily fit groove boards and joints together with minimal stress or effort involved. The tongue and groove woodworking joint is mostly used in panelling, ceiling or wall wood design, and flooring. The wood joint works by slotting the edges of the wooden tongues into the grooves.
2. Type of Woodworking Joints
There are many types of woodworking joints to choose from! The most popular joints in home design and building construction include the following:
- Lap Joint.
- Dado Joint.
- Dowel Joint.
- Butt Joint.
- Miter Joint.
- Mortise and Tenon Joint.
- Through Dovetail Joint.
3. Benefits of Woodworking joints
Different woodworking joints can offer different benefits and these vary depending on who is installing them, and the projects that they are being used for. For example, the butt joint is often the most inexpensive type and is very easy to install, making it great for smaller pieces of furniture. However, the butt joint is also one of the weakest joints which means that if used on the wrong project, you won’t be able to enjoy the benefits!
Tongue and groove boards, in our professional experience, are one of the most stable woodworking joints. They are also incredibly smooth and will last a long time – one of the many reasons why it is the most popular joint for floors!
4. What is a Tongue and Groove Joint?
Tongue and groove joints are a popular wood joining method, which is also commonly referred to as ‘edge to edge joints.’ The joint works on the basis of two key individual parts: the solid tongue joint and the slip groove joint.
The tongue joint is a bit of extended wood that can be slotted into an opening in another block of wood (or similar material)- this opening is called the groove. The edges are then perfectly slotted together to produce a flat and smooth surface, with no need for nailing!
These joints create flat boards that are perfect for use in the house, with their tight joints producing quality floors that will last for many years. These wood joints are also used to create paneling boards and ceiling decorations!
5. How are Tongue and Groove Joints made?
Primarily there are two methods of making tongue and groove joints, these are by machine or by hand:
By machine, you can use a table saw to cut into the wood. In terms of material, it is best to use sturdy wood with consistent thickness when making the joint by machine. Once you have worked out the dimensions for the tongue panel that you will be slotting inside the groove, you can then use a table saw on the edge of the wooden board to create a groove.
After making a first line in your groove, compare its dimensions against the tongue board – this will help you to identify whether your groove is too narrow. You can then recut your groove on the table saw again in line with the adjustments that need to be made. Creating the tongue by machine is basically the same method, but it focuses on the outside edges of the boards, rather than the inside.
Making tongue and groove joints by hand requires a certain level of expertise and can be slightly more time-consuming and laborious. You will require a handplane tool (these can be purchased at most local handyman stores). Again, we recommend using sturdy wood boards that are of a consistent thickness.
6. Why should you use a Tongue and Groove Joint
The tongue and groove joint is one of the most popular woodworking joints used by professionals and D.I.Yers alike! It’s one of few joints that uphold the historic essence of wood binding, and it has been used for infrastructure design since the early periods of woodworking. The fact that it is still commonly used today emphasises its strength and sturdiness.
A tongue and groove joint also doesn’t require adhesives in its most simple form. This prevents the wood from shrinking if the adhesive is to expand – allowing the joint to last longer.
Other woodworking joints, such as the mortise and tenon joints, are much harder to replicate for D.I.Yers. Due to this, this type of joint can be far more time-consuming with higher pricing levels when compared to the tongue and groove joint.
