Frequently Asked Questions
Do blackout curtains really save money on cooling costs in south-facing rooms?
Yes — when combined with a close-fitting shade (like cellular or roller), blackout curtains with a thermal liner can significantly reduce solar heat gain and night-time heat loss. The curtain acts as an insulating layer; for best savings, ensure full coverage and minimize gaps at the sides and top.
Should I choose 100% blackout or room-darkening panels for a living room?
For living rooms in south-facing locations, room-darkening panels can be fine if you mostly want reduced glare and a decorative look. If you need maximum temperature control, better sleep, or TV viewing without glare, 100% blackout panels paired with a daytime shade provide the best performance.
How should I measure my windows for energy-saving curtains?
Measure the full window width and add 12-24 inches (6-12 inches per side) so panels cover the frame and overlap the wall to reduce edge leaks. For length, measure from the rod to the floor and choose panels that either touch or slightly puddle for best insulation. Aim for 2x fullness (total panel width double the window width) for a proper drape.
