External roller shutters

Top-mounted roller shutters

The undoubted advantage of external top-mounted roller shutters (also called window-mounted roller shutters) is their unobtrusive and elegant appearance resulting from the design specifications. The roller shutter box is installed on top of the window or door frame. Next, the tracks are fixed to the outer part of the window frame, and then the whole set is mounted in the window recess. Top-mounted roller shutters are a perfect solution for new or renovated buildings where windows are yet to be mounted, and the lintel has not yet been specifically shaped. We manufacture all external roller shutters to custom measure, which makes them precisely fit to the window joinery.

Features of Nitus top-mounted roller shutters

Better protection

Robust curtains of Nitus window roller shutters provide increased protection of your home. Lowered external roller shutter makes it difficult to break into the house and protects the windows and façade against vandalism.

Protection from the sun and low temperatures

External roller shutters provide excellent protections during summer and winter. In the summer, they protect against sunlight, ensuring the interior stays pleasantly cool, while in the winter they help reduce heating costs.

Protection from noise

External roller blinds provide better acoustic insulation, bringing silence and peace to your home. This may be important for people living in close vicinity of busy roads.

Sleek design

The final visual qualities of top-mounted roller shutters are highly satisfactory. Part of the box hidden under the elevation finish and the guides matching the colour of windows and/or façade make the rolled up shutters almost invisible.

Stable top-mounted roller shutters

The box and guides are made of PVC. Side guides feature brush seals, and the bottom slat includes a rubber seal. Internal inspection plates are available in two options. The inspection plate opened from the bottom (RND) allows the box to be mounted externally or internally, while the plate opened from the front (RNB) allows the box to be built in only externally.
