Great info thanks guys. We were leaning toward honeycomb blinds, but then we came across this:

It's a roller shade, but it's two shades-in-one. You can pull down the sheer shade, or you can pull down both for a blackout function. Anyone have any experiences with roller shades like this?
I wonder how much insulation you actually get from honeycomb, or is that just fancy marketing?
