Tongue and Groove Timber


Providing a range of high quality tongue and groove timber
Tongue and Groove (T&G) cladding is one of the most popular timber profiles, chosen for its strength, neat finish, and versatility in both residential and commercial projects. Designed with precision, each board features a tongue (a protruding edge) on one side and a groove (a matching slot) on the other, allowing the boards to interlock seamlessly. This clever system creates a smooth, continuous surface with concealed fixings, giving you a refined and professional look every time.
At The Larch Cladding Company, we supply high-quality tongue and groove timber suitable for a wide range of applications, from modern home extensions and garden rooms to commercial façades and interior feature walls. Our tongue and groove boards are manufactured to the highest standards, ensuring durability, strength, and an elegant finish that works perfectly whether you install them horizontally or vertically.
Many customers choose larch tongue and groove cladding for its natural resistance to decay, insect damage, and harsh weather conditions. Its warm tones and distinctive grain pattern bring a unique charm to any project, and over time, larch will weather to an attractive silver-grey patina if left untreated. We also offer tongue and groove profiles in cedar and Douglas fir, giving you a choice of species depending on the aesthetic and performance you want to achieve.
Our tongue and groove exterior cladding is particularly suited to exposed areas, providing long-lasting protection against the elements while delivering an attractive, uniform appearance. As with all our timber products, it is FSC® (FSC-C134890) certified and sourced from responsibly managed forests, ensuring sustainability and peace of mind.
Whether you’re an architect specifying timber for a large development, a contractor working on a bespoke build, or a homeowner planning a renovation, our tongue and groove cladding range offers the perfect balance of style, durability, and environmental responsibility.
We’re proud to supply premium-quality trade timber to professionals throughout the UK’s construction and design industries. Whether you’re an architect, contractor, engineer, estimator, or quantity surveyor, our sustainably sourced, precision-cut timber is crafted to meet the demands of today’s building and joinery projects.
