Windows and railings are important details of both the exterior and the interior. By using natural stone in constructing windows and railings, we give them a unique style and look. They can be made of different materials: granite, marble, travertine or limestone, as well as adding underlays and various processing profiles to give them the look you want. Apart from aesthetic value, these elements also have a practical use. They are easy to maintain, and the barrages built into the exterior elements will protect your facade from rainwater pouring and seepage.
