In this video, we present our Old Building EL-Window Mounting Angle. It has been developed for old buildings and is used for exposed reveals, in bathrooms or for interior and exterior window sills. During installation, the reveal remains undamaged, which is important for existing tiles or exposed concrete. Screwing through the window into the angle is immediately blocking. The window fixing with the Old Building EL-FMW takes place in front of the façade.
