Roller shutter box: structure and function
A roller shutter box is the housing for the roller shutter curtain, which is rolled up in the box when open. It protects the mechanism from the weather and ensures that the Roller Shutters can retract and extend smoothly.
Inside there is a roller shutter shaft onto which the roller shutter curtain (the entirety of the roller shutter slats) is rolled up when the shutter is raised. The curtain runs downwards via lateral guide rails and closes the window. Depending on the roller shutter drive - manual by belt or crank or electric - the curtain moves up or down.
Modern boxes are also equipped with insulating materials, inspection openings for maintenance and optional elements such as insect screens or motor drives. Depending on the design, a distinction is made between top-mounted and front-mounted roller shutter boxes. ROMA offers high-quality systems for both variants - tailored to the respective structural conditions and individual requirements.
Top-mounted roller shutter box
A top-mounted roller shutter box is placed directly on top of the window and installed into the wall along with the window. It is particularly suitable for new construction and renovations involving window replacement.
Front-mounted roller shutter box
This model is mounted on the exterior of the facade and is ideal for retrofitting . The advantage: Since no modifications to the building structure are necessary, the thermal insulation remains intact when installing an exterior roller shutter box.
Retrofitting roller shutter boxes: you have these options
Many existing buildings are equipped with outdated or inadequately insulated roller shutter boxes. Retrofitting can be beneficial in several ways.
Retrofitting Ventilation in Roller Shutter Boxes
Specially designed ventilation systems ensure controlled air exchange without the need to keep windows tilted open. This improves indoor air quality and prevents mold growth.
Retrofitting brush seals to roller shutter boxes
With brush seals, you can reduce drafts and dust in the Roller Shutter box . At the same time, sound insulation is improved. Rattling noises when moving the Roller Shutter are also significantly minimized. The retrofit is usually straightforward and is also possible with older roller shutter boxes.
Retrofitting sound insulation in the roller shutter box
If you live on a busy street, you cansignificantly reduce noisewith special soundproofing mats . The materials reduce both structure-borne and airborne noise equally and contribute to a noticeably quieter living environment. This retrofit is ideal in combination with new seals or a complete box renovation.
Retrofitting an Insect Screen into the Roller Shutter Box
An integrated insect screen in the roller shutter box ensures peaceful summer evenings free of mosquitoes and flies— easy to operate and compactly housed. Retrofitting is often possible even with existing roller shutter systems and provides year-round protection without the need for additional modifications to the window frame.

This solution is ideal for automating existing systems, especially for hard-to-reach windows or for barrier-free living.
Roller shutter box: retrofit inside or outside?
Whether a roller shutter box is retrofitted on the inside or outside depends on the structural conditions and intended use. Internal systems are ideal if there are structural restrictions on the outside. External variants (e.g. Front-Mounted Roller Shutters) score points for better thermal insulation and easier integration into the façade.
ROMA recommends individual planning together with a specialist Roller Shutters company to find the optimum variant.
Modernizing roller shutter boxes pays off
