For those of you have never lived in Arizona, you probably don’t know about sunscreens. When we lived in midwest, we had screens on the windows to keep the bugs out. Here in Arizona flying bugs are far and few between. We put screens on our windows during the summer to reduce the amount of heat entering the house. Sunscreens are one way to reduce cooling bills in the summer. When it gets cold, not very often, you can take the sun screens off the windows to take advantage of the suns heat. We have also found that it is not too difficult to replace the fabric in the screens yourself when it gets worn out. It just takes an inexpensive tool that can be found at the hardware stores along with the fabric and replacement rubber tubing if needed.
