Wood tolerates high humidity and is capable of absorbing and releasing water vapor without compromising its structural integrity. This moisture buffering effect of wood is called hygroscopicity. Although problems may arise when wood gets too wet for too long, wood buildings that are properly designed and constructed are durable and perform well in all types of climates.
For this project in the Pacific Northwest, plywood sheathing is used as an exterior substrate, onto which the weather-resistant barrier and cladding would be attached.
