Frequently Asked Questions
Do these curtains really block all light and improve room temperature?
Many NICETOWN lined panels use a sewn-in black liner and triple-weave fabric that produce very high blackout and measurable thermal benefits. Full blackout is typical where the curtain covers the window and hangs close to the wall. For best temperature control combine lined curtains with a tight mounting and use insulating liners or multiple layers if needed.
Can I machine wash thermal blackout curtains?
Some NICETOWN models are machine washable (check the product care notes). Budget lines often allow machine washing on a gentle cycle; higher-weight or double-deck panels may recommend hand wash or dry clean to protect the liner and finish. Always use mild detergent and low heat for drying or ironing.
Will grommet curtains shorten when hung?
Yes — grommet headers create a three-inch sewn header and the fabric folds where grommets sit, which slightly reduces the measured hanging length. If you need exact floor-to-rod coverage, allow for this when measuring or choose a longer length to compensate.
