Interior finishing · Canada

Wood and natural materials, read for a Canadian winter.

Wooden Room collects practical notes on finishing interior rooms with solid wood and other natural materials. The focus is the Canadian context: dry heated air from October to April, wide humidity swings, and the species that handle them.

Topics

Three areas, written from the room outward.

Each topic starts with how a material behaves indoors, then moves to the decisions that follow from it.

The Canadian variable

Indoor humidity is the recurring problem.

In much of Canada, indoor relative humidity drops sharply once heating begins. Wood responds by losing moisture and shrinking slightly across the grain; in spring it takes moisture back and expands. Solid-wood finishing that ignores this tends to show open joints in winter and tight, cupped boards in summer.

Most of the choices described on this site — leaving boards to acclimatize, allowing expansion gaps, picking quarter-sawn stock for stability — exist to manage that single seasonal cycle.
