> For example, I've been meaning to research reflective blinds to see if they do more than normal blinds at keeping out heat. I can confirm they work. It's much cooler in my small flat when they are closed for day, even though they are inside and a little warm. On a sunny day, my outer wall heats up to 60°C. Inside temperature can be 50°C with blinds open or 35°C with blinds closed. This was with outside temp 30°C and wall directly exposed to sun.
