I want to paste some aluminium or paper on the window so there wont be any light but which is more convinient, does paper or aluminium?Which reflects heat the most?thank you
aluminum will reflect the light away much better, it also conducts heat more than paper which is a very poor conductor, but the gain in heat from the paper will be minimal, so i would go with aluminum.
