ᐅ Roller shutters do not darken the room – is this really no cause for concern?

Hello dear forum,

We have the problem that our roller shutters do not provide complete blackout.
We have a small child who can only sleep in total darkness. However, a lot of light comes through the roller shutters. When our little one wakes up, they can of course see everything and do not fall back asleep. On one hand, the light comes through the sides of the individual slats, and on the other hand, the guide rail is so short that light also comes in at the lower corners. I am attaching a picture.
Our site manager and the roller shutter company say that roller shutters do not fully darken and see no reason for any improvements. But we now face this problem, and it’s about our child who cannot sleep. I’m also wondering why the roller shutters in my parents’ house, which is 30 years old, do provide blackout, as do those in rental apartments, where construction is often cheaper.
What do you think?
Is this really the standard?
And is there perhaps another solution to make the roller shutters block out more light?

Please take a photo without the flash. This way, it’s easier to see the actual conditions.

In our apartment, we had curtains that effectively darkened the room... and I’m also sensitive to light in the bedroom.

Thank you very much for your reply.

The picture is taken without flash.

Are these really roller shutters, or are they more likely venetian blinds?

It looks like the rail profile does not extend all the way to the windowsill.

Yes, they are really roller shutters.

And yes, the guide rail does not extend all the way down. We raised this issue, and they said it couldn’t be done differently because otherwise, access to the exterior window sills would have been blocked.
