Frequently Asked Questions
Do thermal curtains actually stop drafts?
Thermal curtains reduce drafts by adding an insulating layer that slows heat transfer through windows and blocks air movement at the window edges. For best results, choose full-length panels, mount them to overlap trim, and pair them with a tight rod installation or an underlayer like a cellular shade.
How should I measure for thermal curtain panels?
Measure the full width of the window including trim, then multiply the usable rod width by 1.5–2x to get the ideal total curtain width for proper fullness. For length, decide whether you want sill-length, floor-length, or puddle-length — measure from the intended rod position to your desired hem and order panels accordingly.
Can I machine wash these panels without damaging the thermal layer?
Most polyester thermal panels in this roundup are machine washable on a gentle, cold cycle and can be tumble dried at low heat; always follow the manufacturer care instructions. Avoid high-heat drying and bleach to protect the fabric weave and any thermal lining.
