Traditional sliding window, usually made up of two sashes that slide up and down in vertical grooves. They are counterbalanced either by weights on cords or by springs.
It is made of fir of the prescribed moisture and three-layer laminated, which increases its mechanical strength and, at the same time, eliminates deformation (warping) along the length. The surface receives a top quality treatment and is coated with water-based ECO varnishes. The varnishes are resistant to external influences and provide a UV barrier, which increases durability and eliminates cracking due to exposure to sunlight and moisture. It can be traditionally divided into a number of glass panes within each sash or with no divisions.
