Charred Accoya cladding

Globally-renowned Barangaroo development

Charred Accoya cladding

Barangaroo House, a three-storey restaurant, was one of the first projects in Sydney to utilise Accoya wood cladding, the world-leading high performance, sustainable wood product, and the distinctive Japanese charring technique, Shou Sugi Ban. Situated in Barangaroo, a dynamic commercial and residential area, Barangaroo House opened in December 2017, the latest venture by one of Australia’s most celebrated chefs, Matt Moran.

The Barangaroo project has sustainability at its heart. With a commitment to becoming carbon neutral, the 22-hectare harbourside site is concerned with zero waste emissions, being ‘water wise’ and contributing to the overall well-being of the community. As a result, the internationally recognised mission celebrates design excellence, natural beauty, world-class eco-living and its aboriginal history to preserve the project for future generations.

The unique split level restaurant was designed by architects, Collins and Turner. Supplied by leading timber experts, Britton Timbers.

Sydney’s Darling Square District

Accoya is the wood of choice

Sydney’s Darling Square District

Accoya cladding has been chosen for the wood siding on the Darling Exchange, part of the Barangaroo reserve. Taking prime position, the Accoya timber cladding stands out on the spiralling 6 story structure at the heart of Sydney’s Darling Square District.

20 kilometres of Accoya exterior cladding was supplied to contractors Lend Lease for the manufacture and installation of an Accoya screen that wraps the exterior of the building in a dynamic and exciting manner.

FR treated by Fire Resistance with their product Flame Fix the building contains a library, childcare centre and market hall as well as a rooftop bar and restaurant with views over Tumbalong Park, the Chinese Gardens and Cockle Bay.


Tested to the limit

External coatings test

Leading timber research institute, BM Trada, tested the stability of Accoya wood against other widely used wall cladding materials by cyclic exposure of coated boards to wet and ambient conditions.

BM Trada found that Accoya cladding had exceptional stability and stated that Accoya used for cladding boards could increase from standard 150mm wide profiles to 200mm when used externally. This increased width specification board shows Accoya wood’s design flexibility and superior performance when compared to western red cedar, larch and thermally modified pine.

Leading timber research institute, BM Trada, was commissioned by Accsys to perform a series of exposure trials. The trials using the same coating began in February 2007 in
Buckinghamshire, England and tested Accoya cladding board’s resistance to natural weathering and splitting in comparison to Pine and Siberian Larch.

This test, using a translucent black coating for maximum radiant heat build is a particularly difficult situation for wood products.

After 3.5 years, Accoya wood was found to outperform the competing wall cladding boards in a number of ways – showing excellent coating performance. Pine cladding boards showed severe levels of fissuring, resin exudation, end fissuring, paint peeling over fissures, shelling,surface checking and board distortion; whilst Siberian Larch was found to have extensive surface checking and burst resin pockets.

Accoya cladding, however, had a flat surface with no grain raising, virtually no shelling, cracking, checking or fissuring. External dirt was easily cleaned off revealing a sound clean surface with no coating issues.

This harsh test proves that Accoya wood has superior coating performance compared to many competing materials.

Though BS EN350-2 does not strictly speaking apply to modified timbers such as Accoya, the BRE have made an assessment that the durability class 1 rating achieved by Accoya wood in trials is equivalent to class 1 of natural timbers. Therefore service life statements attributed in BS 8417 are applicable to Accoya wood.   Under BS 8417, only cladding made from timbers of durability class 1 are suitable for situations where there is a desired service life of 60 years.
