Frequently Asked Questions
Will thermal curtains stop cold drafts fully?
Thermal curtains significantly reduce drafts and heat loss through sliding doors, especially when panels overlap the frame and reach the floor. They don't replace weather-stripping or insulated glass, but paired with draft seals they make a noticeable difference in guest room comfort.
How do I measure for sliding door curtains?
Measure the full width of the door plus extra 6–12" on each side for overlap, and measure from the rod or mounting point down to the floor. Choose panels that together provide 1.5–2x the door width for a full, insulating pleat when closed.
Can velvet thermal curtains be machine washed?
Some velvet panels are machine washable on a gentle cycle, but many recommend dry cleaning or low-heat steam ironing to restore pile. Always check the manufacturer's care instructions; polyester triple-weave panels are generally easier to launder.
