ᐅ Roller shutter guides too short?

Hello,

our roller shutters do not completely block out the light.

I have now noticed that although the shutter closes down to the aluminum window sill, the guides do not extend onto the window sills, leaving a gap on the side through which a significant amount of light comes in.

In another house, I saw that the guides run down onto the window sills and are therefore completely light-tight.

Attached is a photo.
Is this installation correct, or are the guides too short?

These are aluminum roller shutters, in a prefab house.

What do the experts say?

Getting new windows? In that case, the window sill connection profiles should have been notched out (it looks like poor workmanship).

No, it’s a new build, currently being finished. I just noticed it while testing all the roller shutters.

I recall there was a similar topic before:
ᐅ Roller shutters let in a lot of light

I would say it’s quite similar in our case, and the roller shutter guide rail rests on the side track at the window sill. In the corner, wild bees always try to build nests.
We only use the roller shutters as summer heat protection, so we never fully close them anyway. Therefore, I can’t say if they provide complete darkness.

Yes, I have a direct comparison, and it looks different there; it darkens completely, and everything is perfect.

Hello,

Then complain about the other windows. In my case, all the windows are completely darkened because the roller blind guide rails extend all the way down. This also applies to the patio doors. Someone didn’t measure correctly.
