Curtains are an old-fashioned fix for draughty windows, and with highly insulated windows, are only needed for aesthetic flair and privacy. That said, here’s what they can do if your windows with higher U-values in older double glazing and rattling frames are not delivering.

Look for specific thermal interlining when purchasing.
