Finger jointed, laminated or finger jointed and laminated window scantlings, made from suitable coniferous and deciduous woods, are an excellent starting product for the production of windows. This was demonstrated by research projects
of Holzforschung Austria (HFA) and the Institut für Fenstertechnik e.V. (Institute for Window Technology). (ift Rosenheim).
In order to give the user the opportunity to purchase high-quality tested glued wooden window scantlings of consistent quality, the present Technical Guidelines
were developed as a basis for quality assurance and a quality assurance feature was created by marking the scantlings during production.
