Dillon Kyle Architects office building
Gives the wow factor with Accoya
Over the years, the Houston Museum District located in the Montrose neighbourhood has morphed from a residential area into a lively art district, home to art galleries, museums, and aesthetically distinct buildings. When Dillon Kyle Architects set out to design their new office space across the street from the Houston Center for Photography, they needed creative solutions to fit a 5,000 square foot building plus parking on the lot’s small unique space.
An abstract leaf-like pattern was carved into 2,500 eight-foot long by eight-inches tall and 11/16-inches in depth with Accoya wood boards wrapping the entire building. The leaf pattern serves as a gentle reference to the live oak trees that line the neighbourhood. The rainscreen was made of G80 galvanized steel sheets offset from the building with the Accoya leaf boards attached to it.
Selected as the material of choice
Accoya wood siding for new respite center Oregon
PeaceHealth and Ronald McDonald House Charities have built a new respite facility, the ‘Heartfelt House’ featuring Accoya wood for its exterior siding. Located in Oregon, the house provides accommodation for families of loved ones being treated at the Sacred Heart Medical Center, RiverBend. The project completed in May 2019.
The ambition was to provide a more homely feel for guests who have spent long days at the hospital, creating a warm and welcoming environment and connecting them with nature. 2fORM Architecture chose Accoya for the exterior facade to help meet these goals.
Research has shown that exposure to natural materials such as wood rather than today’s common concrete, metals and plastic, can help to promote wellbeing. Accoya being grown in FSC certified and sustainable forests, is Cradle to Cradle Certified Platinum for material health, combining these features with the outstanding performance made Accoya wood the natural choice for the project.
The Accoya siding was manufactured and installed by Tall Pine Contractors. They coated it with Sansin Precision Coat SDF in a custom tint. Sansin finishes are well suited for Accoya, helping to create a warm, beautiful aesthetic.

testing
Tested to the limit
Leading timber research institute, BM Trada, tested the stability of Accoya wood against other widely used engineered wood siding materials by cyclic exposure of coated boards to wet and ambient conditions.
BM Trada found that Accoya wood had exceptional stability and stated that Accoya used for siding 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 siding 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 siding boards in a number of ways – showing excellent coating performance. Pine siding 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 wood, 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 siding made from timbers of durability class 1 are suitable for situations where there is a desired service life of 60 years.
