ᐅ Experiences with "thermal" curtains or fabric roller blinds for heat insulation?

Hello everyone,
Recently, there have been many discussions in various threads about "thermal insulation in modern houses." Keeping the heat out during summer seems to be an even bigger challenge nowadays than preventing heat loss in winter.
Venetian blinds, roller blinds, awnings / sun sails, or even building an overhang? There are different preferences here, which is completely understandable.
But something I haven’t heard from anyone yet is that, for example, in the upper floor children’s rooms on a sunny summer morning, they simply close a "thermal curtain" to prevent the rooms from heating up throughout the day. It makes sense to use a lighter-colored curtain that reflects the sunlight the most. Accordingly, unlike a fully lowered roller blind, it should let in enough light so that the children can play in their room during the day without needing to turn on the lights.
Has anyone installed such special thermal curtains as heat protection and can share their experiences with them?
With Venetian blinds, I see the "office building" look as a disadvantage, and with roller blinds the room gets too dark when they are almost fully lowered. I don’t want to restart the Venetian blind versus roller blind debate here. The focus is primarily on curtains. Or maybe on those double-layered fabric blinds used inside? Do they keep the heat out?
Thanks in advance

For example, west and north windows or south and west windows?

Winniefred21 Dec 2019 12:01Our experience is that external sun protection is by far more effective than internal options. For example, on the south-facing roof window, we initially only had an internal roller blind with a coating. It blocks out light very well and reduces some heat, but only since I installed an external sunshade from Velux has the heat remained almost completely outside. It’s still not quite as effective as the other windows with external blinds, but it’s a significant improvement.
Well, that’s why I always roll my eyes when someone has children’s rooms on the north side, and then it’s said, “Oh, the kids must have the nicer south side.” Hello?
What’s so great about having to shade the room in summer? So, put the kids on the north side, then you don’t have to lower anything during the day.
Our child’s room faces east, and in summer the roller shutter (for some reason we didn’t install an external venetian blind) is left slightly open at the bottom until noon, then it can be raised all the way. Since school is usually on during that time, it doesn’t matter.
In the living area, when we’re home there’s an awning plus an under-awning outside; when we’re away, the external venetian blinds are down. That worked very well last summer.
