Private Home – Sioo treated Canadian Western Red Cedar

Project: Private Home – Sioo treated Canadian Western Red Cedar

Architects: H2 Architecture

Completed: Ongoing

Timber Cladding Species: Canadian Western Red Cedar

Timber Cladding Treatment: Sioo wood protector – Pre-coated in house before delivery to site.

For this high end development Canadian Western Red Cedar was selected, with its characteristic of being naturally durable there is not a requirement to pre-treat this species. The client was after the ‘pre weathered’ silver/ grey look of Cedar – Sioo, a silicon based product speeds up the appearance of weathering.

With the moisture in the air, Sioo will allow the timber to visually change in appearance as seen in the photos. This process is much quicker than the natural weathering process of an uncoated example. More importantly there is more uniformity in the colour change as the moisture in the air is causing the reaction, not the UV rays that Cedar normally weathers from. (Unsightly under overhangs and varying elevations) The photos below show the timber approximately 6 months after installation.

Cladding Profiles: The project primarily uses our Ex 22 x 150mm NWCC1 chamfered cladding board, along with a smaller Ex 22 x 100mm adjusted version of the same profile. Both boards are faced fixed with Stainless Steel annular ring shank fixings. To finish off the detailing around this contemporary design we manufactured a number of bespoke Cills to drawings prodived by the Architect, these we also pre-treated before delivery to site, allowing speed of installation and a consistent coating finish. A standard trim (NWA1) was also supplied to neatly tie in the corner element of this building, ideal to subtlety soften the edges. Sioo (Official Product Page)

Decking: In a number of areas decking was specified on this project, Sioo can also be used on decking so the ‘show timber’ across the whole project could be from the same species with the same Sioo treatment.
