Sawn timber & further processing
SAwn timber use
Versatile, easily workable and natural material
Sawn timber is used for construction applications such as floor and roof structures, exterior cladding, windows and doors, and wall structures. Other uses for sawn timber include various engineered wood products, such as glued laminated timber, cross-laminated timber (CLT) and industrial packaging.
Sawn timber serves as a raw material for many interior decoration products, such as mouldings, flooring and panelling, furniture as well as solutions for outdoor living areas and gardens.
Planed timber is often special kiln-dried, split and/or surface-treated. There is an endless number of various plane profiles available and new ones can be made per customer request. Planed products include mouldings, floor boards, and interior and exterior cladding panels.
STRUCTURAl TIMBER etc.
A finger joint is a strong joint used for extending the length of a timber product. Finger joints make it possible to produce strong, straight, knot-free and long sawn timber, or to only use heartwood, for example. Finger-jointed sawn timber is used, for example, in the furniture and window industries.
Glu laminated timber
Glued laminated timber is made by gluing together at least two lamellas of strength-graded sawn timber. Various solutions, dimensions and strength grades are available. The primary uses for glulam timber are load-bearing structures, and the products are standardised according to SFS – EN 14080.
The rot-resistance of timber products designed for exterior uses is improved by impregnation. The impregnation agents used for sawn timber contain copper-based compounds and give the timber either a green or brown colour. There are two impregnation classes, A and AB, to match the intended use.
exterior cladding etc.
Thermal modification, or heat treatment, increases the biological durability of sawn timber and decreases deformations due to moisture variations. The process does not involve chemicals, and relies only on a high temperature and steam. The treatment may also modify the colour of the wood.
Typical end uses
Differend tree species and different grades are used in different kind of end uses and applications. The most typical end uses and their grades are listed here.
