Frequently Asked Questions
Are these curtains machine washable?
Yes — all three Lazzzy panels list machine-washable care (cold). Use a gentle cycle, avoid high heat drying, and steam or iron on low if needed to reduce creases. Follow the care label for best results.
Will these curtains block street noise?
Heavier, denser fabrics like velvet do help dampen sound compared with lightweight curtains. The velvet panels here will reduce echo and soften street noise, but they won't create complete soundproofing — combine with seals, carpet, and heavier window hardware for better results.
Which header style works best for full blackout?
Rod-pocket panels are shown for these products and provide a close fit, but for tighter blackout you can add a grommet header or use clips with a wraparound blackout liner and a close-fitting curtain rod. Ensure the rod and mounting are sturdy to support heavier velvet panels.
