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?

For complete darkness, either the guide rail or the end piece would have needed to be notched out.As I have already noticed, the original poster does not have external thermal insulation composite system (ETICS) and therefore no sliding piece that could be notched out. They should have simply made the guide rail longer.
