Top-mounted roller shutters, also known as surface-mounted roller shutters, are mounted onto the window during construction and installed as a permanent unit in the window opening. They are suitable both for new buildings and for window replacements during modernisation projects. Unlike front-mounted roller shutters, they are always flush with the façade and invisible from the outside when open. Thanks to the heroal IB Unique insulation box system, heroal top-mounted roller shutters provide superior insulation values that can meet passive house standards and be flexibly adapted to any window size with a variety of box sizes. Find out more about the many possibilities of top-mounted roller shutters.
Depending on your requirements, you can choose between a roller shutter box that can be opened from the inside or a roller shutter box that can be opened and closed from the outside.
