Overview
Timber by nature is hygroscopic – if the environment is wet the wood will swell and if it is dry then the wood will shrink and warp.
During the manufacture of window frames, furniture and other similar products a dry atmosphere will cause the wood to shrink and this will result in gapping at joints and in the corners of frames. Where veneers are also used additional problems will occur causing the edges to become uneven and in some cases develop cracks.
By maintaining an even and correct humidity level during manufacturing process a good quality finish will be achieved with the additional advantage of airborne saw dust being suppressed from the surrounding air providing a safer environment for the workforce.
