Greetings. I live in San Antonio area of Texas, so it's very hot in the summer. My house faces east/west, with our living room and kitchen area on the west side windows. Our daughter's room is the east facing side. Our windows had wood blinds installed already when we bought it. I like the natural light coming in from the windows so I don't have to turn lights on, and we usually keep the blinds mostly/totally closed to help keep out the sun and some of the heat. I open the blinds somewhat during the day to let in some light, but not when the sun is directly blazing in (like in the morning, or the winter months where I open windows if it's cool enough out). I don't want to put curtains up to block the light. Do you have any thoughts or ideas on how to help keep out more of the heat without using curtains? Thank you.
