Last summer when we had a heatwave, I tried out some window coverings as an experiment. The two south-facing windows are large, and have a cement driveway outside them, so a lot of heat radiates into the house. With one, I covered it with aluminium foil, on the inside, and the other had shade cloth hung on the outside (my kids whinged about how bizarre it looked, but I told them that the silver tinfoil looked kind of Christmassy
) Both of these methods made the area inside much more comfortable, so now I'm looking for a longer term solution.
I'm thinking of exterior blinds, but want ones that can be retracted, and also that allow some visibility out. I've been looking at Bunnings and online, and come across two basic types: shade cloth type material blinds, and ones that are made of a fabric that resembles heavy-duty insect screening. I'm wondering whether anyone has any experience of how effective either type is in keeping out heat, while allowing some visibility?
