Officially unveiled at Ecobuild 2016, Brimstone is the first commercially available thermally modified British timber.

Sourced exclusively from English and Welsh woodlands, the Brimstone range is designed for cladding, decking, external joinery and furniture, and includes thermally modified British hardwoods including ash, sycamore and poplar.

Brimstone Ash (New)

Officially unveiled at Ecobuild 2016, Brimstone is the first commercially available thermally modified British timber. Sourced exclusively from English and Welsh woodlands, the Brimstone range is designed for cladding, decking, external joinery and furniture, and includes thermally modified British hardwoods including ash, sycamore and poplar.

The thermal modification process re-configures the wood to deliver a material of high stability, durability and aesthetic uniformity that is resistant to water and fungus. The Brimstone range represents new levels of sustainability for specifiers interested in modified timber products, as the process does not rely on impregnating the timber with chemicals.

By using homegrown timber the development of Brimstone creates value for the UK’s native woodlands.

The Product and Benefits

A proven technology, thermally modified timber is 60 – 80% more stable than non-modified timbers, meaning significantly less expansion and contraction when faced with changes in ambient temperature and humidity, making thermally modified timber a superior solution for a range of exterior uses.

The thermal modification process also results in a product that is naturally durable to its core. Similar thermally modified hardwood products reach the equivalent of Class 2 EM350 and in some cases Class 1, giving a minimum service life of between 30 – 50 years.

Brimstone products are currently being tested by the BRE for durability, stability, strength and hardness. Results will be available by the end of 2016 and we will make this information available on our website.
Imported thermally modified products are already widely available and growing in popularity as the benefits become more widely recognised. What sets Brimstone apart is that it is produced exclusively from trees grown in English and Welsh woodlands, and from species that are currently underused, thereby supporting our local domestic woodlands and offering clear benefits with regards miles travelled, carbon impact and wider social value to the UK.
