Frequently Asked Questions
Do blackout curtains actually reduce air conditioning and heating costs?
Yes. Dense, triple-weave or lined blackout curtains reduce heat transfer through windows by blocking solar gain in summer and slowing heat loss in winter. The savings depend on fit — longer panels that overlap the frame and close fully deliver the best results.
Will these NICETOWN curtains reduce outside noise?
They help. Triple-weave, heavier polyester panels absorb more mid- and high-frequency noise than single-layer, lightweight curtains. For best results pick longer, heavier panels and make sure they cover the entire window and extend past the frame.
How do I choose the right length and width?
Measure from the rod to the floor and add a few inches if you want a puddled look or subtract for just-touching. For width, each panel should be at least 1.5–2x the window width when combined so the fabric pleats properly and blocks light at the sides.
