$this->bbcode_second_pass_quote('HamRadioRocks', 'S')ome of the windows on the southwest and northwest faces of my house are exposed to direct sunlight due to the lack of a tree or awning to provide shade. (Since I rent, I'm not authorized to make home improvements.)
So I just taped aluminum foil to the interior of these windows. The blinds don't do the best job of shading - they are beige and only partially obscure the direct sunlight. Aluminum foil, on the other hand, is opaque and also reflects the sunlight AWAY from the house. Since less direct sunlight can get in, the rooms should heat up less. If I really want to be a purist, I'd cover the glass entirely, but I'm leaving small gaps between the window frames and the foil coverings to let in a little bit of light.
I'm surprised that none of the experts on energy conservation suggest this. This is a cheap and easy solution. I also figured that if aluminum foil works well for the window shade in the car, it should work well for the house as well.
If nobody would objects taping it to the outside would be slightly more efficient for reflection, that way the pane of glass does not pass the light twice absorbing a portion in the process.
I am considering taping foil reflective side in on the inside of some of my windows this winter to try and reflect some of the heat back in, it is an old house with wooden single pane windows I can not afford to upgrade soon.
