Frequently Asked Questions
Do insulated blackout curtains actually reduce drafts?
Yes — curtains with a sewn-in blackout liner and dense triple-weave fabric reduce air exchange at the window and door area, lowering drafts and improving perceived warmth. For best results mount the rod high and wide so curtains overlap the frame.
Can I machine wash lined blackout curtains?
Care varies by model. Some NICETOWN premium long panels are machine-washable on a gentle cycle, but many lined designs recommend hand wash or dry cleaning to preserve the liner and fabric. Always check the product care instructions before washing.
Will blackout curtains block outside noise too?
They can help. Heavy, multi-layered curtains absorb a portion of ambient noise and reduce reverberation, but they won't soundproof completely. For significant noise reduction combine curtains with weatherstripping, heavier rods, and overlap at the edges.
