Description
Iroko is widely regarded as one of the most premium hardwoods for exterior cladding, known for its rich colour, natural oils and impressive strength. Grown in West and Central Africa, Iroko has long been used in high-end construction, boat building and luxury joinery, earning its reputation as a timber that performs in harsh outdoor environments while aging beautifully over time. It’s often called “African Teak” due to its similar characteristics and long service life.
Our 94mm x 14mm Iroko Tongue and Groove cladding boards offer a sleeker, lighter profile that’s perfect for refined, modern cladding projects. This slimmer board size is ideal where a more delicate, detailed finish is desired, without compromising strength or stability.
The tongue and groove profile creates a clean, interlocking joint that delivers a smooth, seamless surface with excellent protection against wind and rain. These boards are a popular choice for garden rooms, summerhouses, exterior feature walls, sheds and modern façades.
When freshly installed, Iroko displays stunning golden to medium brown tones, which naturally mellow into a soft silver-grey patina if left untreated. To retain the warm colour and slow down the weathering process, we recommend applying a quality wood oil or OSMO stain, which also helps protect the surface from UV exposure, moisture and cracking.
If you’re looking for a cladding option that feels genuinely premium, refined and built to last, Iroko is hard to beat.

1. What are Iroko T&G boards typically used for?
They’re ideal for exterior cladding on summerhouses, sheds, garden rooms, outbuildings and feature walls.

Iroko is extremely dense and naturally oily, giving it excellent protection against moisture, rot and insect attack without chemical treatment.
3. Does Iroko cladding need to be treated?
It doesn’t need treatment for performance, but using OSMO oil or stain is recommended to preserve the rich colour and enhance surface protection.
4. How long does Iroko cladding last?
With correct installation and maintenance, Iroko cladding can last 50–60+ years.
5. What fixings should I use?
Always use stainless steel nails or screws to prevent corrosion and staining.

It can be used internally, but it is primarily designed and recommended for external use.

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.
