That's not cheap - it cost me $50 to do the big window.
So you want to get it right the first time.
And that helped quite a bit, but not enough.
I don't have an awning on that side of the house - that's NEXT year's project - but realize I need something to break the sun beating into the window.
I put the umbrella up outside my door and Man! I immediately felt a difference.
Just pray a gust of wind doesn't come up.
