Are you a homeowner, self-builder and renovator looking for a high-quality, long-lasting cladding and decking material for your home? Then, Brimstone timber cladding is where it's at. Their thermally modified, locally sourced British timber creates a cladding that is very durable, stable, and visually attractive.

A sustainable, UK-made alternative to imported timber, you can choose from different timbers to match your architect's best laid plans, and match your design ambitions. Low-maintenance, visually attractive, and long-lasting. What's not to like?

What is Brimstone?

Getting straight to the point, Brimstone is an acclaimed cladding and decking material carefully crafted from thermally modified British hardwoods. Manufactured in the UK by Vastern, it undergoes a precise thermal process that heats it to 210 degrees, enhancing the wood’s natural qualities with only heat and steam, with no chemicals involved.

The way the hardwood is treated not only makes it eco-friendly but also permanently enhances its durability, stability, and moisture resistance, making Brimstone ideal for tough indoor and outdoor applications.

Unlike imported hardwoods or chemically treated softwoods, Brimstone is responsibly sourced from UK-managed forests and made locally. Supporting local forestry and the British timber supply chain reduces the carbon footprint associated with imported materials.

Where is Brimstone used?

Natural timber has a unique beauty that is hard to replicate, yet it is also a hardy, versatile material. And it is these qualities that make Brimstone cladding an obvious choice for self-build and home-renovation projects. It's the perfect choice for exterior cladding, interior feature walls, and external decking.

Architects and self-builders should choose Brimstone for contemporary extensions and new-build homes where consistency of appearance and long-term performance are essential. A great example of Brimstone cladding in action is this North Somerset eco-house.

The choice of timber was especially important to the property owner, who was keen to use natural, sustainable timber that would maintain its colour and appearance. The home uses large areas of Brimstone ash cladding that have been exposed to the weather, yet continue to perform with minimal movement or maintenance.

Elsewhere, Brimstone cladding has been installed as decking on residential projects where homeowners want a natural timber surface that remains stable and durable year after year. Beyond its simpler uses, Brimstone cladding’s enhanced stability makes it suitable for a wide range of detailing styles, including rainscreen cladding, vertical or horizontal profiles, and clean-lined decking installations.

Choices, choices, choices

You don’t just get one choice of timber cladding when working with Brimstone. So what do you get to choose from? Their range includes three main species: Brimstone Ash cladding, which is durable, stable and relatively knot-free. Brimstone Poplar cladding is a lightweight, stable and durable locally grown alternative to Canadian cedar. And, there’s Brimstone Sycamore cladding with a low knot content, making it an attractive and reliable choice for external wall cladding on contemporary properties.

And it's not just the choice of timber that makes Brimstone cladding a must-have. There’s a range of timber cladding profiles suitable for both external and internal wall cladding, with the option of rough-sawn or smooth finishes. And, if they don’t have a profile to suit your needs, they can make you one.

What makes Brimstone perform so well?

Timber cladding is timber cladding, surely. The simple answer is no. Brimstone's thermal modification process is key to its performance and what makes it an award-winning project.

By altering the timber’s internal structure through heating, Brimstone timber cladding becomes more stable and far more resistant to decay and moisture absorption. This means boards are less likely to warp, cup, or split — common issues with external timber.

Brimstone has been on buildings for over 10 years now, so we have a decade of real-world experience.
