Vastern Timber

Vastern Timber is one of the UK’s longest-established sawmills, known for supplying high-quality British-grown timber to self-builders, renovators and design professionals. Based in Wiltshire and family-run for over a century, the company focuses on producing durable, locally sourced wood products with a strong emphasis on responsible woodland management and technical know-how.

Vastern Timber offers a broad range of timber cladding, including British larch, western red cedar, sweet chestnut and oak. Its team provides guidance on species choice, profiles, fixing methods and detailing – support that many self-builders find invaluable when navigating a material that varies greatly in appearance and performance.

A key part of its range is Brimstone®, a thermally modified British hardwood developed to offer improved stability and durability. It has a refined, contemporary appearance and has been used across residential and commercial projects looking for a long-lasting alternative to imported hardwoods.

Alongside cladding, Vastern Timber supplies solid and engineered hardwood flooring, plus timber for landscaping and bespoke projects. Its online Resource Centre features technical information, installation guidance, case studies and answers to common questions – a useful reference point for anyone planning or specifying timber.

Brimstone thermally modified timber cladding

Brimstone is a thermally modified hardwood produced in Britain using locally grown species such as ash, poplar and sycamore. The timber is heated to around 210°C in an oxygen-free chamber, a process that improves stability, increases durability and reduces the wood’s susceptibility to decay – qualities that make it well suited to external cladding and decking.

The result is a refined, largely knot-free hardwood with a clean, contemporary appearance. Brimstone provides the look and feel of premium hardwood but with enhanced performance, offering a credible alternative to imported timbers.

Because it’s made using British-grown wood, Brimstone also supports more sustainable forestry and reduces transport impacts. It appeals to architects, self-builders and homeowners who want a long-lasting cladding material with strong local provenance and a modern aesthetic.

With its combination of visual quality, dimensional stability and low maintenance requirements, Brimstone is a strong option for anyone considering durable, sustainable timber cladding for their project.
