Brimstone Poplar Features

Brimstone poplar is a thermally modified timber cladding made of British grown poplar. It is durable, stable and beautiful as well as being the lowest priced specie in the Brimstone range. Being relatively free of knots and lightweight Brimstone poplar is a locally grown alternative to imported Canadian cedar cladding.

Brimstone uses hardwood sourced exclusively in Britain, helping to support our woodland economy. Poplar is a fast growing renewable material, responsibly harvested and Grown in Britain certified.

Brimstone poplar is transformed by thermal modification, a chemical free process that reconfigures wood by superheating it to over 200 degrees. The result is a stable and durable material, highly resistant to pests and rot, and certified to withstand the weather for over 30 years.

Brimstone poplar has a consistent dark chocolate brown colouring with a silky grain pattern and regular birds eye pips. The wood will contain only occasional small sound knots.

Working properties
Thermally modified woods are more brittle than untreated wood. Care should be taken when cutting and nailing to prevent chipping and break out. Pre-drilling is advised.

Density
377 Kg / M3

Extractives
The modification process involves no chemicals and most naturally occurring chemicals in the wood are removed during the process. Thermally modified wood can be treated as inert.
