Location

Also known as Brazillian Teak, Cumaru grows widely across South and Central America. Architects Walker Nicholas used its varied colouring to bring a fresh look to timber cladding in this project, featured on TV’s Grand Designs programme.

 

TTF Member Bennetts Timber only sources FSC® certified Cumaru for its cladding, machining it for this project in their own milling facilities. Bennetts arranged to have the Cumaru kiln dried to 7-10% moisture content, giving it an above-ground service life of some 30 years.

 

Cumaru cladding is naturally resistant to rot, insect attack, mould, fungus and decay. It requires little maintenance and no treatment prior to installation. Though Cumaru is difficult to work, Bennetts Timber has the expertise to do so. Cumaru planes and finishes to a smooth surface and can take a high polish. Cumaru cladding naturally weathers to an attractive grey over time. The extent to which it changes colour is highly variable, and every project is different.

 

To reduce the rate of colour change, Bennetts Timber can apply a clear treatment containing a UV filter, which will occasionally need to be renewed. A further alternative is to apply a stain which will maintain its rich variation in colour. With their specialist cladding knowledge, Bennetts Timber can offer both machining and timber treatment facilities. Stains and treatments are factory-applied, ensuring consistency.
