ᐅ Roller shutters allow a lot of light to pass through.

Hello 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?

As I said before: we have it exactly like you do, without an end cap, whether transparent or in anthracite.
We have a simply structured rail at the bottom. And I asked you what you have there. #20

Do you also have space between the window frame and the shutter rail, like the original poster?

For us, the rail is directly attached to the window frame.

In our case, the rail is directly against the window frame.
Yes, as I said before, about 2 cm (1 inch). Today I fully lowered the roller shutter on the south-facing window. It was completely dark. You could only see a slight reflection from the two bottom slats on the inside when standing very close to the window, and even then only within a radius of about 10 cm (4 inches).

I think ours are installed incorrectly. I’ll look into it this week and report back as soon as I know more.

I can’t really say exactly how it looks in our case. But when our roller shutters are down, it is pitch dark, and that is exactly how we want it.

I completely understand that it can be disturbing; as someone who suffers from migraines, it simply has to be pitch dark for me as well.
