Why specify sweet chestnut

Six arguments to bring to the table.

Proven durability

More than a century of documented service on historic buildings. A solid argument in front of any client.

Zero maintenance

No treatment, no staining, no replacement. The wood silvers and weathers on its own, with no intervention.

Low-carbon asset

A bio-based material that stores carbon and takes little energy to produce: an asset for your environmental targets.

Heritage-approved

A traditional material recognised in heritage restoration, compliant with the French DTU 40.29 and 41.2 codes.

A look of its own

A play of shadows and a patina that neither slate nor tile can reproduce. A true architectural signature.

Traceable chain

French timber, an ultra-short chain, made to order: complete traceability for your project files.

Heritage

A material trusted on historic monuments.

The hand-cleft chestnut shingle is a traditional material many centuries old, found on countless listed buildings: church spires, castles, barns and outbuildings. Its use is compatible with the requirements of the Architectes des Bâtiments de France, the French heritage authority.

Compliant with the French DTU 40.29 (roofing) and 41.2 (cladding) codes and with Eurocode 5, and recognised by the French RE2020 regulation for its biogenic carbon storage.
