BRE - Reducing kiln-drying twist of Sitka spruce

Organization: BRE
Publication Date: 1 January 1998

This paper describes the extent and significance of twist in UK-grown and commercially prepared Sitka spruce. It describes how top weighting during kiln drying, together with modified kiln schedules, can limit twisting, and assesses distortional stability of timber under fluctuating humidity conditions in storage and use. This paper will be of interest to sawmillers, timber agents, suppliers and specifiers.
