The renovation frame is used for constructing windows that will be installed in historic buildings, on old wooden frames (without removing them). Before installing the renovation frame, it is necessary to inspect the wooden frame for wood quality (damage, moisture). If needed, the old wooden frame should be re-impregnated with appropriate agents. It is also important to ensure the possibility of ventilating the wooden frame that remains in the reveal. When preparing to install the new renovation frame, the old one must be properly processed. The renovation frame is installed from the inside. From the outside, depending on the building conditions, it is possible to install a suitable masking angle profile.
