rema S2 frames are designed for installation on an existing wall. This type of product can be installed after finishing the wall and floor. It's possible to install the complete door set, steel frame and door, in one step on the finished existing wall.
The great advantage lies in installation. As the rebate part and sleeve part are separate, it is possible to fit them hidden by screws behind the rubber seal. In order to meet requirements and ensure a high standard of quality, the mitre joints are fully welded. In this way, the frames can get a final powder coating that is clean and smooth on the surface without any visible unevenness in the area of the mitre joints.
