ᐅ Practical size for windows and roller shutters (or blinds)

Good evening,

We are currently planning two fairly large patio doors in our living area.

1.: Height: 2.55 m (8 ft 4 in) Width: 3.20 m (10 ft 6 in)
2.: Height: 2.55 m (8 ft 4 in) Width: 2.40 m (7 ft 10 in)

The plan includes a built-in roller shutter box with a height of 25 cm (10 inches). Flush ceiling lintels are planned in the concrete ceiling. The floor construction measures 20 cm (8 inches). The rough construction height is 3 meters (9 ft 10 in) (from the top of the raw floor to the underside of the ceiling).

The height is composed as follows:

- 20 cm (8 inches) leveling element for screed due to floor construction up to the finished floor surface
- 2.55 m (8 ft 4 in) window/door height
- 25 cm (10 inches) built-in roller shutter box

= 3 m (9 ft 10 in)

My question to the experts: Should I reduce the width of the openings to avoid problems with the roller shutters? For example, instead of 3.20 m (10 ft 6 in), make it 3 meters (9 ft 10 in)?

The other windows in the building are planned by the architect with a width/rough opening of 1.60 m (5 ft 3 in) (double windows).

Thanks and regards

I don’t want it to sag or require a special custom-made solution either.

I think their glass sizes have long since gone beyond the standard 😉

The roller shutters are then simply produced with a separation; this is quite common.

Does separation then also mean two roller shutter boxes with two motors?

I am thinking more along the lines of: one box, one shaft, one motor – just two pairs of guide rails and two sections of blinds.

Great. I was missing that information. Thanks.

Is it also possible to feed the power cable for the motor into the roller shutter box from above? We operate every roller shutter with a power cable from the utility room (controlled via KNX). The cables are routed through the concrete ceiling and then come out of the ceiling above the roller shutter. Connection to the motor is made via Wago terminal block inside the box. I would like to avoid a junction box and drilling into the exterior wall.

Here is the floor plan of the ground floor with the two windows. The window openings can still be changed.
