Hausbau1221 Jun 2024 05:52Hello everyone,
our roller shutters let in an extreme amount of light at the bottom left and right corners, causing the entire shutter to be illuminated. This is very disturbing, especially in the bedroom and children’s room. The pictures show the roller shutters fully closed, yet the light only comes through the bottom corners.
Someone from the company took another look (only from the outside, they did not check from inside) and said this is how it’s supposed to be. I have never experienced such light penetration in any apartment before, so I find this quite strange. Here is the response we received by email afterwards:
Depending on the type of roller shutter and the guide rail construction, more or less light can enter here. The roller shutter type and guide rail construction were requested by us as specified in the scope of work, and we offered and finally installed exactly this construction.
According to the RAL guidelines, the roller shutter guide rail must not align flush with the window drip edge; there must be at least 8 mm (0.3 inches) of space, less is not permitted, and we have achieved these 8 mm (0.3 inches) in your case.
---
Of course, our service contract from the architectural firm did not state that the shutters should let in as much light as if there were no shutter. I would not understand why such constructions should even exist either.
My questions now are:
How is it with you? Do you experience this kind of brightness? How do your corners look? Would you say this is normal?

Buchsbaum06621 Jun 2024 08:35That looks a bit like a poor job.
The side guide rails are definitely too short. They should extend all the way down to the window sill and be finished at the bottom with a plastic end cap. You are missing this end cap.
It is called a closure cap for the roller shutter guide rail. This sits flush on the window sill and prevents any light from passing through. They must have measured incorrectly. Especially since rainwater can get in there.
Also, the roller shutter curtain is running crooked in the guide rails. This could be because a holder at the top on the shaft is broken. The bottom closure rail must lie airtight with the rubber on the window sill. Or your window sill is not level.
It will be one of those two.

Hausbau1221 Jun 2024 08:53Thank you for your assessment.
I also took some photos of the guest bathroom from the outside since I can easily access it from there. Sorry for the dirty window sills; I should probably clean them.
I briefly visited the neighbor and checked it from the outside as well. He also doesn’t have any cover at the bottom, but his trim extends further down, although not all the way to the window sill either.

Buchsbaum06621 Jun 2024 09:04As you can clearly see in your pictures, dirt accumulates behind the opening of your guide rail in the corner.
I measured and installed my roller shutters myself. Mine fit flush with the windowsill at the bottom, using these plastic end caps.
Otherwise, the bottom sealing bar with the rubber does not seal properly. There should be no gap between it and the windowsill. Either the end stop is incorrect and the shutter curtain doesn’t fully close, but I don’t think that’s the case since the ventilation slots are closed.
Or something is misaligned, so it rests on one side at the bottom but not on the other. That is not normal.

Hausbau1221 Jun 2024 09:17So, the black rubber (or whatever it is) rests along the entire width on the window sill. I think it only looks like there is a gap in the photo. I am attaching more pictures.
I looked for end caps, but I can’t find any that would fit because the rail is so short...
Regarding the window builder’s statement:
According to the RAL guidelines, the roller shutter guide rail must not be flush with the window sheet; there must be at least 8 mm (0.3 inches) of space. Less than that is not allowed, and we do achieve those 8 mm (0.3 inches) with your installation.
I measured, and in our case, it’s 2 cm (0.8 inches). But of course, you can also allow for at least 8 mm (0.3 inches) with 2 cm (0.8 inches)…

Our roller shutters look exactly like those in TS’s setup, meaning:
- The guides do NOT extend all the way down to the windowsill – this would be very complicated because the windowsill has a rebate on both sides, as shown in TS’s picture. Good luck with the precise cutting – and I would immediately remove any cover, as it only collects dirt.
- Yes, we also have about 8 mm (0.3 inches) of clearance on each side.
- No, we do NOT have a rubber seal at the bottom.
- Yes, for us it is “dark” when the shutters are lowered – however, the gap between the shutter and the window is significantly smaller.
Okay: not all rooms are equally dark, and “dark” is always subjective – personally, I see extremely well in low light and during the day I’m the first one outside to put on sunglasses.
Since I can’t judge the lighting conditions relative to the sunlight intensity at that location, I find it difficult to evaluate – what you consider “maximally disturbing” we probably wouldn’t even notice, as we never close the shutters completely at night. I can’t sleep like that and feel like I’m in a submarine. Just no.
My conclusion: works as is – state of the art.
