ᐅ Daylight Entry – Electric Roller Shutters Do Not Close Properly

Good day.
I had electric roller shutters installed in my new apartment (retrofit).
Now I have noticed the following and have already informed the roller shutter installer.
- In the bedroom and the children’s room, not all slats close properly. In the bedroom, it’s 3 slats, and in the children’s room, 2. Naturally, light comes through here.
- Additionally, I get a lot of light coming in (from 5 a.m. onward, because it’s the east side) because the side rails don’t extend all the way down to the windowsill, but stop about 3 cm (1.2 inches) before it!
So, on the right and left sides, light shines strongly through a gap of about 3x1 cm (1.2x0.4 inches).

The roller shutter installer says these side rails must not go all the way down to the windowsill because of rain. But 3 cm (1.2 inches) is quite a lot!

Of course, I don’t expect complete darkness, but something reasonable. However, with these large gaps on both sides plus the slats, it’s impossible to sleep from 5 a.m. in the summer...

What can or should I do now?

Thank you very much,
erika

Even if the guide rails do not extend all the way to the windowsill, the bottom of the window frame should still provide light protection.
The roller shutters should extend beyond the glass edge, that is, also over the approximately 10cm (4 inches) frame, so that no light can come through.
If light passes through the gaps between the slats, the roller shutters are not fully closed at the bottom. They should be, but in your case, it doesn’t sound like they are.

Please upload a photo of the lower part of a guide rail.

The roller shutters should extend beyond the glass edge, so also beyond the approximately 10cm (5 inches) frame, to prevent any light from coming through.
If light passes through the gaps between the slats, it means the shutters are not fully closed at the bottom. They should be, but in your case, that does not seem to be the case.

Attached is the light penetration below the guide rail.
Regarding the slats: 2-3 lock together in the middle of the roller shutter! So the roller shutter does run all the way down!

Now I understand: the roller shutters are not mounted in front of the window but attached to the outer edge of the facade. That is probably the correct way to do it?!

However, this is obviously inconvenient when you need complete darkness.

Did he cut something out there? For us, it’s also not a 100% seal because the roller shutters sit on a facing brick layer, but this is quite unusual.
I might consider attaching a "rubber lip" there that would seal the gap and, if necessary, give way slightly (in case it closes unevenly again).
