You could use one of these with foil or aluminium sheets, to pop up near the window pane & put into maybe, a few Christmas tree stands, around your office, larger workspaces, so to keep the heat out... So not to over heat windows. xxx As you have a space below and at the top... They'll be some colourful scenes, in some offices and schools, even hospitals etc during heatwaves that's for sure. As all you'll need to do is just drill an aluminium sheet onto the existing windbreak or just staple on some foil at home with your kids, making it a "fun" eco friendly project. With kids even older students you could use colourful foil sheets, using PVA and stapling on, making all sorts of shapes,. collages to combat the heatwaves of the future too !!! Let this become a revolutionary innovation idea for schools to incorporate into their design teams, as life skills, as well as making larger screens of the future for all industries, where needed !!! xxx Beloud
