@buffyleigh@mas.to A roll of reflective insulation has gone a long way towards cutting down on solar heat gain in my apartment, with its unshaded south & west facing windows. (It's like bubble wrap coated in a mylar emergency thermal blanket.) I know other folks use aluminum foil (or even better, a mylar blanket) over foam poster board — or you could use solid foam insulation panels, which would be a little sturdier for a large window like a sliding door.
From my experience, you want something that can get as close to the glass as possible, without sealing air into a greenhouse space that will overheat. So, cut to fit each window pane separately.
But as for today, well: sunset is only 3¼ hours away. 🫠

@AmeliasBrain@mstdn.ca Is that something you can remove/replace each day? We do need some sort of pergola-type structure in front of the door outside because opening it to let the doggo in/out increases the temp 0.5 degrees every single time past noon. The window is right beside so we might get be able to have a shade over both outside. But not cheap, have to make sure things are absolutely fastened down with our wind these days, etc.
