Cathy Schwabe Architecture Hi -
The siding is Western Red Cedar -- it was applied using a rain screen assembly with a fully vented and screened back side. We use 3 coats of a penetrating sealer -- the first coat was applied prior to the installation, so that all faces of each piece of wood were sealed. The second two coats were applied to the visible surfaces - and every cut joint was also sealed during installation. I expect that depending on the orientation, the siding will need refinishing, every 3 - 5 years to keep it well protected.
One alternate to consider would be the composite wood products by companies such as Hardie - especially if regular maintenance is not appealing and if the natural wood look is not essential to your design.
Thanks for the question.
