Brimstone poplar external cladding is an innovative and entirely natural timber product ideally suited to both commercial and residential properties.

Drawn exclusively from woodlands across England and Wales, Brimstone is the first and only thermally modified wood produced from locally grown trees. In addition, being a fast growing plantation species, poplar is an easily renewable raw material and a very efficient carbon store.

Brimstone poplar is produced by heating British grown poplar to 215 degrees in a controlled atmosphere. The extreme heat alters the cell structure of the wood, removing moisture, extractives and cellulose. This natural, toxin-free method results in natural wood that is very durable, stable and consistent.

The appearance of Brimstone poplar is dark brown with a silky grain and relatively few knots, well suited to contemporary facades where clean, straight lines are required. If left uncoated Brimstone poplar will weather naturally to a grey patina or alternatively it is possible to coat the product with an oil based UV resistant coating to maintain a brown colour.

Brimstone poplar is classed as very durable (Class 1 EN 350-2) offering a locally grown alternative to Canadian cedar and other durable old growth timber species.

Available as vertical timber cladding, horizontally timber cladding, profiled cladding and sawn cladding. Profiles available include shiplap, halflap, tongue and groove, matchboard and square edge. Cladding profiles can be both face fixed or secret nailed. Bespoke cladding profiles are available.

All Brimstone products are derived from well-managed British woodland. GIB certified.
