Tongue-and-groove cladding is made from wooden boards that fit together (either vertically or horizontally) with the extended notch on one board locking into the rabbet (recess) on the other. Tongue and groove cladding offers durable, watertight construction with a sleek finish.
Tongue and groove boards, unlike waney edge, get planed and cut. Their profile hides the join between boards and offers a watertight face. T&G refers to the joining of the notch (tongue) into the groove (rabbet) to create a single flat surface.
Tongue and Groove Cladding
Now, we should all be familiar with the basics of cladding. All set with shiplap, overlap, and tongue-and-groove?
Then, as this is an ultimate guide to tongue and groove cladding, let’s more on to why it’s so popular. Then we can look at how to build your own T&G shed and what you need to bear in mind.
Are you after the perfect combination of quality, weather resistance, durability and price? It’s a tongue and groove shed.
Tongue and groove is also great for people who store expensive tools and machinery in their sheds. The interlocking panels make it much harder to break into than, say, overlap panelling.
This also means your shed is more protected against water ingress. And it’ll be better insulated. This is one of the first major steps in looking at how to damp proof your shed.
Tongue and groove also offers the aesthetics of exposed timber. But, it comes in a clean, modern design. If you’re looking for a more rustic exterior to your garden buildings; think overlap.
Like shiplap, though, tongue and groove boards also contract with the climate. This makes them less prone to rot and warping. T&G’s robust nature is why it’s also so popular as a flooring material. It can withstand heavy, prolonged footfall.
And if you’re worried about a DIY project - don’t be. Tongue and groove cladding is easy to put together. It’ll only need you, a friend, and a bit of time to construct a T&G shed. Plus, you won’t need many tools.
The great thing about tongue and groove cladding is that it can be used for:
Outdoor garden buildings
Installing it in your ceiling can be easier than using plaster sheets. You can then stain the boards whatever colour you want. With two people: measure your ceilings and cut T&G boards. Then, affix to your ceiling joints through the tongue joins and fit the panels together.
A similar process applies to tongue and groove flooring. But boards will still need to be nailed into your subfloor.
Tongue and groove cladding can be laid horizontally or vertically, depending on where in your house you’re decorating. The good thing about T&G is that there’s no way to get it wrong. This is especially true if all your boards are the same length and size.

Tongue and groove cladding is designed to offer a watertight, weather-resistant finish. Although, it also has enough wiggle room to expand and contract in hot weather. This means that it’s unlikely to crack or rot.
If you’re buying a T&G shed from Garden Buildings Direct, you can opt to have it pressure treated. This is where timber is locked in a vacuum in a vat. It’s then treated with preservatives and chemicals.
Barring that, you should:
Remove any old paints and treatments with a solvent-free oil remover
Built using tongue & groove panels, the Bella has a secure and stable structure that’s built to last. The panels interlock, creating a smooth finish that enhances the style of the summer house. The interlocking tongue and groove panels form a strong connection which creates a high degree of structural strength.
The Renna Summerhouse is also constructed using an interlocking tongue and groove method. The T&G boards provide a smooth engineered finish, which complements the modern style of the building. Each panel is 11mm thick and provides the summerhouse with excellent strength.
Pressure Treated Options
And for ultimate protection and longevity, we recommend opting for a pressure treated garden building. Pressure treatment is an extra step in the construction process, where the wood is treated in a pressurised tank, and chemical preservatives are forced deep into the wood’s fibres to resist rot, weathering, and pests.
This protects the wood inside and out and is better than regular dip treatment, as this only coats the surface of the wood. By pressure treating the wood, you’re left with a building that is low maintenance and cost-effective. You may even save money in the long run thanks to freeing yourself of maintenance worries.

Tongue and Groove Cladding for Sheds
And we’re done! Well done for making it this far. Now you should be an expert on tongue and groove cladding. That goes for whether it’s sheds, flooring, or decking.
We hope you’ve found the answers you need so you can make the best choice about shed cladding. But we’ll recap just in case – tongue and groove cladding:
We think that tongue and groove sheds offer all the benefits of shiplap at a more accessible price point.
If you’re working on a large scale construction where water run-off is a necessity, though, shiplap may be a slightly better option. For the average garden shed, summerhouse, or log cabin, tongue and groove construction is a perfect choice.
Here at Garden Buildings Direct, we believe that tongue and groove is the most superior all-rounder. As for shiplap’s claims to better runoff and waterproofing? Some people even say that T>ackling Condensation In Your Garden Shed
