Thses shutters are used in newly built buildings and are a special construction system. The components of this system guarantee quick and easy adaptation of the shutter to any type of masonry. This system provides secure and stable fastening to the structural components of the building and effective thermal and acoustic insulation. The stability of the box is guaranteed thanks to the strong reinforcement made of steel and thanks to the aluminum plaster carriers. RKS shutter box is fully in-built. As a result, this system goes perfectly to the architectural concept of the building. We can use any type of profiles (PA-39, PA-45, PA-52, PVC-37 or PVC-52) in any color range.
