@grams super easy, they are vertical sliding secondary glazing. There’s a wee button in the centre, press that and you can slide the secondary unit pieces up or down and then you can access the sash, it’s a 2 second operation!
@tyeness I was so nervous about how shit they could look, and obviously read lots online about other peoples views (for/against) but I really could not complain about these at all and I’m generally quite particular about details.
@tyeness here are some pictures of one secondary glazing unit. They have wood surround as the glazing is in a bay of sorts to needed the angled edge.
