Frequently Asked Questions
Do thermal curtain panels actually save on heating bills?
They can reduce heat loss at windows by adding an insulating air layer and reflecting radiant heat back into the room. The savings depend on window quality, how well the curtain fits, and how you use them; pairing tight installation with a thermal lining yields the best results.
How should I measure for curtain panels to maximize insulation?
Measure the full width of the window including frame, then choose panels with combined flat width 1.5–2x the window width for good pleating. Mount the rod 4–6 inches above the frame and extend the rod beyond the sides to reduce edge light and drafts.
Are thermal curtains machine washable?
Many modern thermal panels are machine washable on a gentle or cold cycle, but always follow the manufacturer care label. Heavier or lined panels may recommend low-heat drying and gentle handling to preserve the liner and weave.
