Custom window treatments by JC Penny. I had two of my windows done by them and am very happy.

I'm curious what your cold nighttime temps are... and if the insulation is great?

This will depend how much darkness you require to sleep. Where there is issue of privacy....etc. Or other.

For me? Nothing at all on the small boxy windows. If you need light control? You need a custom shade for the transom, shades mounted on the doors. I would skip any decorative "panels" /curtains. You're not going to be able to click and buy anything. Find a Hunter Douglas dealer in your area, and ask for an in house visit.

To me? When an architect does something like this? He ought to be taken to a woodshed, and beaten senseless. Total OVER DESIGN. : ( with no consideration of function within the structure.But geeeee whiz. So cute from the putside??

IMO I'm in the northeast USA. Last night the temp went down to 30F and we had our first snow of a few inches. The wind was fierce last night. Regarding insulation - are you talking about the curtains, or my home insulation in general? My heating situation is insane and a very long story that I can't get into here! I have wall to wall carpeting all over. All of my window treatments are lined. My condo was built in 1980, and I don't know what the insulation is in my walls. I'm on a concrete slab (no basement), so that helps in the heat retention department. I put those plastic kits from a home center on all my windows - even my huge slider. I have sheers on 75% of my windows. You may not think sheers make a difference, but in my opinion they do. I put the plastic between the sheer and the curtain (so the sheer is closest to the window). Years ago I attended a class from my local Cornel Cooperative Extention to find out all the things I can do to keep the home energy efficient all year 'round. A gigantic rug with a rug pad will keep your place warm as well. I am a frugal person, so I make sure to bundle up in the home in the winter. Also I put weather stripping all around all the doors and windows of my home. In the winter I keep the curtains drawn all the time for warmth, except for when there is a sunny and unseasonable warm day for the winter. That may be too much for people who need light and have SAD (Seasonal affective disorder). One of my friends has that, and she has a really cool light box that she uses. Look at all your doors and windows as heat escape hatches.
