Why Choose British Larch Shiplap?
British Larch is renowned for its strength, natural durability, and beautiful grain patterns. As one of the UK’s toughest softwoods, it performs exceptionally well outdoors without the need for chemical treatments.
Over time, the timber gently ages from rich reddish tones to a stylish silver-grey, creating a timeless, weathered aesthetic.
Compared with imported alternatives, home-grown Larch offers a more open grain and rustic texture, adding unique character to each installation while supporting local forestry and reducing carbon footprint.

FAQs
1. What is Shiplap cladding?
Shiplap cladding is a traditional timber profile with overlapping boards that interlock to create a water-resistant exterior surface. The overlap design helps shed rainwater while providing a smooth, uniform look — ideal for sheds, houses, and garden rooms.
2. Is British Larch suitable for exterior cladding?
Yes. British Larch is naturally durable and resistant to decay, making it one of the best softwoods for exterior use. Its density and resin content allow it to withstand harsh weather conditions without requiring chemical treatment.
3. Does Larch cladding need treatment?
Larch can be left untreated to weather naturally to a silvery grey, or treated with a UV-protective oil (such as Osmo UV Oil) to preserve its warm colour and extend its lifespan. A light recoat every 12 months keeps the wood in excellent condition.
4. How long does British Larch cladding last?
With correct installation and periodic maintenance, British Larch cladding typically lasts 20–30 years. When well-cared for, it can exceed this lifespan even in exposed environments.
5. How do I install Larch Shiplap cladding?
Fix boards horizontally with stainless-steel nails or screws, ensuring adequate ventilation behind the cladding. Start from the bottom and overlap boards correctly to allow water to drain. A professional Cladding Install Guide is available for step-by-step support.
6. Can Shiplap Larch be used indoors?
Yes, it can be used internally for feature walls or decorative panelling, though it’s most commonly installed externally. For indoor use, consider applying a clear finish to stabilise the timber and reduce surface movement.
7. What is the difference between Shiplap and Tongue & Groove cladding?
Both offer tight-fitting joints, but Shiplap has a visible overlap that helps water run off efficiently, while Tongue & Groove boards lock together for a flush, seamless finish. Shiplap provides a slightly more traditional appearance with enhanced weather protection.
8. What fixings should I use with Larch cladding?
Use stainless steel fixings only. Other metals can react with the timber’s natural acids, leading to black staining and corrosion over time.
9. How does Larch change in appearance as it weathers?
Freshly machined Larch features warm reddish-brown hues that gradually fade to a soft silver-grey when exposed to sunlight and rain. This weathering process is purely aesthetic and does not impact structural integrity.
10. Is British Larch sustainable?
Yes. Home-grown British Larch is a renewable and sustainable timber, often sourced from managed UK forests. Using local timber helps lower transport emissions and supports British forestry.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.
