Tongue and Groove Timber Cladding

Tongue and groove timber cladding is one of the most popular choices for creating a clean, professional timber finish that actually lasts. The interlocking design gives a tight, neat fit between boards, helping to keep out wind and rain while creating smooth, consistent lines across your building.

This beautiful range covers everything from small garden projects right through to full house façades, and includes premium options in larch, cedar, redwood, iroko and more – so you can choose the right timber for your budget, environment and design style.

Why choose tongue and groove timber cladding?

Tongue and groove cladding isn’t just about looks.

The boards slot together with a dedicated tongue and groove profile, which creates a strong, stable surface that handles the British weather far better than simple flat boards. It’s great for:

• Garden rooms and garden offices
• Sheds, workshops and garages
• Home extensions and feature walls
• Commercial buildings and modern façades

Because of the tight-fitting profile, you get a more weather-resistant finish, better wind protection and a cleaner overall appearance.

A wide choice of timber species

We supply tongue and groove cladding in a wide range of high-quality timbers, so you can match the performance and look to your project:

This means whether you’re building a simple shed or a high-end architectural project, there’s a board here that fits.

British larch – precision made in Devon

The British larch tongue and groove cladding is a real standout in the range.

It’s made from home-grown British larch and precision-machined in Devon using Ruby’s in-house production facilities. That means tighter tolerances, more consistent profiles and a higher-quality finish compared to mass-produced imported boards.

It’s a great option if you want something that performs brilliantly outside while also supporting British-grown and British-manufactured timber.

Looks great, works hard

You can fit tongue and groove cladding horizontally or vertically depending on the look you want. Leave it untreated and it will naturally weather to a silver-grey, or treat it with oils or stains to lock in colour and boost protection. Not sure how much you need. Consider reading our quick guide.

It works just as well on modern garden rooms as it does on traditional sheds, barns or contemporary house designs.
