I know that I am going to love this 10' by 13' rectangle sail shade in the color red. (I hope the color red doesn't make it seem warmer). I probably should of chosen blue, a cooler cooler. I have not been able to put it up yet due to the fact I am a 65yr old female waiting for help from family to install it. Can't wait. I plan to put it   from back of house over back door area like a patio cover. Will make a big difference in how much heat will enter home through back door and window.
