Does anyone have these? I'm considering them for two north facing windows and I like the idea of the thermal/insulating, energy saving properties.
If you have them, do they actually make a difference in terms of keeping the warmth in and cold out?
I think DuoShade (and DuoLights) are specific to blinds2go, but I think they go by the generic terms of honeycomb or cellular blinds, so any other recommendations for this type of blind are welcome.
