Best to darken the windows at night?

Hello,

we have built (single-family house with gable roof, ground floor and upper floor, brick-clad exterior walls). On the ground floor, we have roller shutters.

We are now looking for a way to darken the windows on the upper floor as effectively as possible, so that hardly any light comes in from outside (street lamps etc.). Films are out of the question because they would continuously darken the rooms. Unfortunately, we have found that many retrofitted blinds always have certain "gaps" at the edges, which allow a lot of light in again. It is also difficult that one window is integrated into the roof slope.

Can you recommend specific products that, in your experience, protect the rooms almost completely from light intrusion at night?

For the (Velux) window in the sloping roof, there are track-guided blinds. They are really blackout if you choose the appropriate fabric.
For normal windows, something like that should also be available.
Although a plain roller blind running in front of the wall also works quite well. Heavy curtains are also an option, but they might seem outdated.
Sleeping in total darkness is a matter of getting used to, and I would especially not try to train children to do so.

Roller shutters ... just simple roller shutters. They are also available for [Dachfenster].

I agree - just don't get used to 'total darkness' & absolute silence; that usually doesn't work in hotels / vacation rentals / elsewhere anyway and you create unnecessary problems.

Blinds are generally not really 'opaque'; shutters are better, but then no air can get through either.

Otherwise, there are blackout curtains.

Exactly something like that combined with blinds, and it is properly dark.

For a normal window, we have a grey roller blind from Ikea in a room. Nothing gets through.
