Wooden windows are made from laminated wooden scantlings consisting of multiple layers glued in thickness (lamellae). The middle lamellae of the scantling are usually finger-jointed, the external can be both jointed (the so-called “glued” or optimized scantlings) and solid unjointed (fixed scantlings). Windows are made from a variety of materials of wood species.

The bottom of the frame contains cuts for the easy installation of internal and external windowsills. Let’s not forget wood is exceptionally environmentally friendly and offers the lowest heat conductivity of any frame material.
