Genuinely interested: do you have external shutters or awnings on buildings like schools in Italy? I have to pay £500 to a council planning department to get them approved to be installed. (Which is utterly ridiculous)
Sure but they don’t work as-well because the energy has already penetrated the glass and now needs to traverse the glass again to escape, better than nothing but not as good as external shutters
