Brimstone Sycamore Cladding Features

Being both durable and stable Brimstone sycamore is functional as well as being very attractive. The silky grain and natural ripple often found in sycamore, is accentuated by the thermal process resulting in a stunning visual affect.
The durability and colour of thermally modified sycamore make it an ideal alternative to imported Canadian western red cedar and tropical hardwood species for both indoor and outdoor cladding.
Brimstone uses hardwood sourced exclusively in Britain, helping to support our woodland economy. It is a fast growing renewable material, responsibly harvested and Grown in Britain certified.
Brimstone sycamore 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.

Characteristics

Appearance
Brimstone sycamore is a consistent brown colouring with a silky grain pattern. The wood may contain occasional small sound knots.

Weathering
The modification process removes most natural extractives resulting in relatively consistent weathering that is largely free of staining. Weathering to a grey colour occurs more quickly than for non-modified timber. Surface mould sometimes grows on south facing elevations; this can be neutralised various treatments or white wine vinegar.

Desired service life
Occasionally wet 60 yrs. Frequently wet 30 yrs.

Movement class
Small

Resistance to impact
Medium

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
550 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.

Installation
