Description
Crafted from sustainably sourced, home-grown British Western Red Cedar, these shiplap cladding boards combine natural warmth, striking grain character, and dependable performance.
Each board features a planed smooth finish and a shiplap profile, where boards overlap neatly to create a water-resistant, shadow-line appearance — perfect for sheds, garden offices, exterior walls, and fencing.
British cedar is naturally durable, lightweight, and low-maintenance, making it an excellent choice for both traditional and contemporary architecture. Over time, its light reddish-brown hues mature gracefully to a silvery-grey patina, adding long-lasting elegance to any project.

FAQs – British Cedar Shiplap Cladding (145mm x 19mm)
1. What is shiplap cladding?
Shiplap cladding is a profiled timber board with a rebated overlap that creates a tight, water-shedding joint. It gives a clean, uniform finish with a subtle shadow line, making it ideal for modern and traditional exteriors.
2. How does shiplap differ from tongue and groove cladding?
Shiplap boards overlap each other, while tongue and groove (T&G) boards interlock. Shiplap creates a more defined horizontal line and offers excellent water runoff, whereas T&G provides a smoother, continuous face.
3. How long does cedar cladding last?
With correct installation and basic maintenance, cedar cladding can last 20–30 years or more, thanks to its natural resistance to rot and decay.
4. Does cedar cladding need to be treated?
Cedar doesn’t require treatment, but applying a UV-protective oil or Osmo finish every 12 months helps preserve its natural colour and prevent surface cracking or warping.
5. What colour changes should I expect over time?
When first installed, cedar displays light red and honey-brown tones. Over time, exposure to sunlight will naturally turn the surface to a soft silver-grey, giving a beautifully aged appearance.
6. Can shiplap cedar be used indoors?
Although mainly designed for external cladding, cedar shiplap can also be used for interior feature walls if a rustic or natural aesthetic is desired.
7. How is shiplap cedar installed?
Boards are fitted horizontally or vertically using stainless steel fixings. Each board overlaps the one below, ensuring good drainage and a secure, weatherproof surface.
8. Is British cedar as good as imported Western Red Cedar?
Home-grown cedar has a more open grain and visible knots, offering a rustic, characterful look. While slightly less dense, it provides excellent durability and a significantly lower carbon footprint.
9. What wastage should I allow for?
Because home-grown cedar is a natural, ungraded timber, allow for up to 15–20% wastage to account for natural variations such as knots or sap pockets.
10. Are free samples available?
Yes — free cedar samples are available to help visualise the colour, texture, and finish before committing to a larger order. Email us for an order.

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.
