Solar Screens can keep a lot of sun out. They come in different strengths of 90% and 80%. 90% is a bit thicker so it lets in less sun. The frames and the inner material come in a variety of
colors. We charge $5 per sq.ft. for 80% and $5.5 per sq.ft. for 90%. We use Twitchell Textilene product. Click here to see their website and screen colors.
