Under the influence of atmospheric moisture differences in the whole-ruble beam, stress occurs, which is why it is deformed over time, worsening the functionality and tightness of the entire structure. In order for a wooden beam used to make a window does not succumb to deformation, it began to make it glued. The quality of the gluing elements in such a beam is ensured by the use of high -strength synthetic glue and a specifically for this developed method of gluing wooden surfaces into a microship, which increases the gluing area by half.
