Frequently Asked Questions
Do thermal curtains really reduce drafts and heating bills?
Yes. Well-constructed thermal or triple-weave curtains add a layer of insulation at the window, reducing heat loss through glass and gaps. They won’t replace structural upgrades but can noticeably reduce drafts and help lower heating costs when used correctly—especially when panels overlap frames and reach the floor.
How do I measure my windows for thermal curtains?
Measure the rod-to-floor or rod-to-sill height and the width of the full window opening. For best insulation, choose panels long enough to reach the floor or puddle slightly and a combined panel width 1.5–2x the window width for proper fullness. Consider extra-wide panels for large windows to reduce seams.
Can I machine-wash thermal curtains without damaging the insulating layer?
Most modern triple-weave polyester thermal panels are machine-washable on a gentle cycle and designed to withstand home laundering. Always follow the manufacturer care instructions—cool water, mild detergent, and low-heat drying or air dry to preserve color and fabric structure.
