We have blinding afternoon sun and were going to have to pay big $$$ for sun shades until I thought, Let's try a room divider instead.  You had many choices but the one we selected fits our decor nicely.  Even better?  As the sun shifts, all we have to do is move the light weight screen to block the rays as the sun moves.  When we don't need it for the sun, it folds up very easily and we're able to look out the windows-no problem.  We're thrilled as we also saved lots of money!
