Aluminum Foil on Windows for summer heat or what works?

Does Aluminum Foil really work to help beat the summer heat?I live in San Diego which is known for having perfect weather pretty much all year round, but just yesterday we are starting to get some record breaking heat. Most apartments, condos, and houses do not have A/C because like I just mentioned it's usually in the high 60s or low 70s during the spring and summer, perfect.Will Aluminum Foil work or can someone else suggest anything else?!PLEASE note that I'm just putting aluminum foil on my bedroom window which just faces some other apartment complex and I am not concerned with the aesthetics. I might consider putting something up (but just not sure what) on the living room window other than aluminum foil since everyone can see that window.

Answer:

First, get rid of the black curtain. Black absorbs solar heat, truthfully, any dark color. Put up white or a very light color instead. That will reflect the heat back out. You can buy an insulated pull shade or use automotive window tint on the window to help too. Another idea is to cover some foam board with foil and stick that in the window. And keep your bedroom door closed since you now have a window a/c unit. Good Luck!
Realize that foil is a conductor of heat. Your best action would be to open the top 1/4 of your window and also the bottom 1/4 of the window . This would get convection rolling, or a cooling breeze going, even if you are closed in, even in a ventilation column. Use sun blocking shades in the hot early morning sun and the hot evening west sun. Use the open on the top- open on the bottom- window idea to create the loss of heat - even moreso than a fan... which creates heat! Try using a room partition such as a pretty 3-fold dressing screen to stop the blazing sun from heating your space. It is a moveable shade screen to be used for your advantage.Stay cool Babe!
If it was me id put window tint that has a reflective(aluminum coating) facing outward. It works well and is more appealing,also your apt mgr may not approve of the foil on the window.

The aluminum foil does work, shiny side out. It just reflects some of that bright afternoon sun to keep the room from heating up. I use a window film I found at Home Depot that is UV filtering that works too. You cut it close to size, spray the window with water put it on. You squeegy out the water get rid of the bubbles and use a razor to trim it to exact size. Both of these work, it just depends on whether or not you want to eleminate any light that comes into the room or not.
