I bought these for 2 bedrooms to block out light, cold air, and more importantly sound from ongoing construction on our street. I was so impressed with them, that I bought them for my living room as well. I like that they hang on their own rod, so I'm not committed to the dark, heavy, pricier black-... Read More

  • “Each panel is 45" wide. The outside dimensions of my windows is 36". I like to open my curtains in the center. If I buy two for each window, I'm sure I won't like the amount of fullness the liners would have--unless I'm imagining the weight and thickness of the liners.

    Are they supposed to be flat or have the fullness any curtain or drape would have? If I split the panel in half and hang it flat behind the curtain, would it look ok and give me the heat savings I need? ”

    • If you split the panel in half and hang both halves in the window, I think they would be fine and you could then open from the center. I used tension rods and hung them sideways with clip on hooks in my wide, shorter windows. I could then hang blinds, curtains or whatever on an outside rod. I also like to hang my rods wider than my windows so when open I don't sacrifice any of the light or view. These would be easy to cut and make whatever size you wanted. 2 panels in your window would be too bulky. I think the flatter they are when closed the better. And I liked mine up against the glass on the tension rods too. Good luck.

    • Understand that these should attach behind a drape or curtain, ideally on the same rod. For maximum benefit they should be flat/flush with the frame. For a 36 inch window, I would think that would be your best solution. The cut edge should be hidden under the drspe or curtain.

  • “I want a white or off-white liner. The color choice says 'assorted.' What does that mean?”
    Asked by Tressa from Massachusetts on 1/18/2015 11:40:42 AM
    • I really do not know. My liners are pretty much as pictured, but the dark gray may not be as dark and one pair is more taupe.

    • The ones I got were white on the outside (faces window) and grey on the inside (facing curtain)

  • “Hi, Can these liners be trimmed if they are too long, will they still be effective? Thanks!”
    Asked by HikerGal from NE on 5/23/2014 8:15:47 AM
    • Mine fit perfect. I would suggest measuring your length. I'm sure that they will work even if hemmed.

    • Hello,
      I think you could trim and rehem the fabric to make it work
      I don't know if I would just cut them and leave them unhemmed, not sure if they might fray.

    • I didn't have to but they look like they can be trimmed. Effective in what? Keeping the light and cold out? I'd think so.

  • “How do these attach to rod pocket drapes? You show them used in a picture but doesn't show how.”
    Asked by Joyce from Nevada on 4/5/2013 10:23:57 PM
    • Liner has 1 1/2" diameter metal rings at the top of the curtain.

    • I know this is an old question but in case someone else needs an answer. Everything I could find says that you're supposed to used drapery hooks. Attache them to rod pocket panel and hang the liner using the rings or loops.
