Square
A Kantel is a wooden stick ( timber ) of high quality, for the production of dimensionally stable components used, in particular windows and door Friesen . Scantlings, which are used to manufacture windows, usually have a square cross-section.
Today scantlings are mostly made as glued laminated timber . Three, more rarely four layers are put together and glued , which severely restricts the later twisting of the wood (glued timber scantling) . As a rule, knots, cracks and pockets of resin (and possibly color deviations) are cut out of the wood so that only flawless, flawless sections are used. Before gluing them in layers, these are usually finger-jointed to form longer pieces. In this way one obtains dimensionally stable squared timber that would be difficult to cut from naturally grown wood.
Scantlings for windows that are exposed to unprotected weathering on the "weather side" should be made with a continuous top layer , i.e. H. the outer layer is not finger-jointed.
variants
- A solid wood scantling consists of a solid piece or glued pieces of sawn timber that are at least board thick.
- A stick-glued scantling is considered a solid wood scantling. However, the core consists of thin, rod-like glued lamellas and thus shows a non-uniform appearance. This reduces the formation of cracks and further improves the warpage stability.
- A layer-glued scantling consists of wooden slats glued together in layers. This gluing creates a barrier effect that reduces warping and cracking and increases stability.
