Description
Crafted from home-grown British Western Red Cedar, these Tongue and Groove (T&G) boards combine natural beauty, durability, and precision machining.
Each board is planed smooth for a clean, modern appearance and features an interlocking tongue and groove profile for a seamless, professional fit — ideal for exterior cladding, fencing, garden rooms, and contemporary outdoor designs.
British cedar is naturally rot-resistant and low-maintenance, making it perfect for outdoor use without chemical treatment. Over time, the warm reddish-brown tones gently weather to a stylish silver-grey, creating a timeless, natural finish that suits both rustic and modern aesthetics.
These boards are machined in-house for consistent quality and accuracy, ensuring easy installation and a snug fit. For a cohesive look, matching corner trims are also available.

Customer FAQs
1. What does T&G mean in cedar cladding?
T&G stands for Tongue and Groove, a profile where one board has a projecting “tongue” and the other a matching “groove.” This allows boards to interlock tightly, creating a smooth, seamless surface ideal for exterior cladding or decorative walling.
2. What’s the difference between T&G and shiplap or square-edge boards?
T&G boards provide a flush, joint-free appearance, while shiplap boards overlap slightly with a visible shadow line. Square-edge boards don’t interlock and are better for open-joint or slatted designs. T&G offers the neatest and most weather-resistant finish.
3. Is British cedar suitable for outdoor use?
Yes. Home-grown British Western Red Cedar is naturally durable (Class 3) and resistant to rot and insect attack. It performs well outdoors without chemical treatment and is perfect for cladding, fencing, and garden structures.
4. Does cedar need treating before installation?
Cedar can be left untreated for a natural look. However, applying a UV-protective oil or Osmo Natural Oil Stain helps retain its warm reddish tone and slows down the natural greying process caused by sunlight.
5. How does British cedar differ from imported Western Red Cedar?
Home-grown cedar has a more open grain, visible knots, and a slightly rustic character compared to imported cedar. While less dense, it’s still highly durable and offers a more natural, textured aesthetic that many prefer.
6. What colour will the cedar turn over time?
When new, cedar displays light reddish-brown tones. As it weathers, it gradually transitions to a silver-grey patina, depending on sunlight exposure and moisture levels.
7. How should T&G cedar boards be fixed?
Always use stainless steel nails or screws to avoid staining and corrosion. Fix through the tongue where possible to hide fasteners and achieve a clean, uninterrupted finish.
8. Can these boards be used horizontally and vertically?
Yes. T&G cedar can be installed horizontally, vertically, or diagonally, depending on the desired design. Just ensure proper ventilation and water runoff for long-term performance.
9. Is home-grown cedar graded?
Home-grown cedar is not formally graded, so boards may include natural features such as knots, sap pockets, or shakes. This variation adds to its character and rustic charm, but a 5–20% wastage allowance is recommended.
10. Are free samples available?
Yes. Free sample boards are available to view the grain, tone, and finish before ordering. Samples help ensure the right match for your project’s design and colour preferences.

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.
