About windows, there are many things you don't know

Doors and windows not only decorate the building and make the people living in the house feel comfortable and open, but also are an important part of the exterior style and facade effect of the building.

Different doors and windows can be classified by performance, purpose of use, structure and material.

The active windows we see every day can be summarized as casement windows, upvc sliding windows and other types. Casement windows can be divided into inward casement windows, outward casement windows, swing windows and tilt and turn windows; upvc sliding windows can be divided into right and left upvc sliding windows, and lifting upvc sliding windows.
