How does this impact things like ventilation in the summer?
Just thinking that the time they're most needed is in the summer, and with the heat in recent summers it could cause an issue.

Yeah - not ideal for ventilation but better than nothing . We have windows open and blinds down all day/night. When the sun swings round and comes off the east facing side if we are around I pull the blinds up to increase air flow. The blinds defo help reflecting some heat back but only external shutters - triple glazing and rebuilding two whole facades and roof would actually solve our issue 🤣.
The channels are going to restrict air much more.
with the sleep stuff - I feel your pain - but before you know it they’ll be old enough to make themselves breakfast and play switch …

we had some where the roller and channels were attached to the window frame immediately adjacent to the glass, so didn't interfere when the windows were open.
this was in EU land, mind - so not sure how ubiquitous they are.
they do look a bit cheap, all plastic and self-adhesive, but worked pretty well.

These - we just got regular rollers with blackout fabric because - money - but they are decent and with design award etc. so I imagine the full job is pretty good.
