Species of Timber Available Colours and grain patterns can vary widely from the examples shown, but the photographs are intended as a reasonable guideline as to what you might expect in the selected timber. It should be appreciated that timber is a natural product and therefore no two pieces are exactly the same. The property that causes timber to swell and shrink due to air moisture, is called hygroscopicity. The common method of preventing this is to seal the surface of timber so it cannot freely come into contact with the air. Paints, varnishes and lacquers are used for this purpose. All faces of the timber, seen and unseen, should be coated, paying particular attention to end grain surfaces.
Cedar Canadian Western Red Cedar is the most stable timber available for door construction. High colour variation can make it difficult to perfectly colour match doors. Cedar can easily vary from chocolate brown, to a redish colour. (See next timber sample for other colour variations). Care needs to be exercised when handling Cedar because of its soft characteristics. |
