Frequently Asked Questions
Do blackout curtains actually save on energy bills?
Yes. Blackout and thermal curtains reduce heat gain in summer and heat loss in winter by blocking direct sunlight and creating an insulating air layer at the window. Proper fit (covering the window and overlapping the frame) and heavier or lined fabrics improve savings.
Are these NICETOWN curtains machine washable?
Most NICETOWN polyester panels are machine washable on cool cycles, but lined curtains sometimes recommend gentle washing or dry cleaning to preserve the liner. Check the care tag for the specific model before washing.
Which saves more energy: shades or curtains?
It depends. Cellular shades typically have the best single‑product insulation value, while layered treatments (a cellular shade plus a heavy curtain) provide the highest combined R‑value. For large windows where shades are impractical, thermal curtains are an efficient, cost‑effective choice.
