Tongue and Groove Joining System: Why it’s the preferred choice of floor installers and how it benefits you
Renowned over many years for its superior performance and minimal issues during the installation process, it’s no surprise that tongue and groove is the preferred joining system among many builders and floor installers.
Let’s discuss what the tongue and groove joining system is, the suitable installation methods, and why it not only benefits installers but homeowners as well.
What is the tongue and groove joining system?
The tongue and groove joining system refers to floorboards designed with a protruding tongue on one edge and a groove cut out on the other. The tongue on one board slots snugly into the groove of the adjoining board, resulting in a strong and stable connection.
Installation is simple, as the boards fit together easily, producing a smooth, seamless finish.
What are the benefits of the tongue and groove joining system?
Apart from being versatile across different installation methods, the tongue and groove joining system has many benefits for both homeowners and builders.
These include:
Aesthetic appeal
The secure fit ensures no visible gaps between boards, creating a smooth, seamless look throughout your space. This clean finish suits both traditional and modern design schemes.
Stability and Durability
This proven joining system forms a strong, stable joint that reduces the chance of creaking and squeaking. The boards support each other, distributing weight and stress evenly, resulting in a floor capable of withstanding daily wear and tear for many years.
Quick and easy to install
Its classic design makes installation straightforward for any floor installer.
Larger raft sizes
When installed as a floating floor using a cross-linking PVA adhesive, larger raft sizes can be achieved. Because the floor behaves as one sheet, there is no risk of boards sliding along the joins or binding during natural expansion and contraction. This reduces the need for internal expansion joints.
Installation over hydronic heated slabs
Yes; with a few simple extra steps and the right know-how, both installation methods can be successfully used over hydronic heated slabs.
What are the installation method options for tongue and groove flooring?
Tongue and groove flooring can be installed using either a Direct Stick method or a Floating Floor method.
Direct Stick Installation Method
Compared to other joining systems, tongue and groove boards are very straightforward and efficient to install via direct stick. Adhesive is applied directly to the subfloor, and the boards are bedded into the adhesive, ensuring a long-lasting finish with no movement underfoot.
Pros:
• Less movement underfoot, resulting in a superior feel and increased longevity
• Can be refinished like a traditional timber floor
• Suitable for installation under kitchens and cabinetry
• Enhanced design flexibility
Cons:
• More costly than floating
• A professional installation is required
Floating Floor Installation Method
Where a floating floor is preferred, a cross-linking PVA adhesive is applied along the groove before the next board’s tongue is tapped gently into place. This secure bond minimises any potential creaking and ensures the joining system remains tight over time. The glue also acts as a sealant, forming a barrier against small accidental spills.
Pros:
• Quicker installation
• DIY & budget friendly
Cons:
• Less overall stability
• Slight floorboard movements can be experienced
• Lower perceived value compared to a direct stick installation
