- Is this worth it for soundproofing a room?
- It helps with echo and mid-to-high frequencies, not with bass or loud neighbors. For real sound isolation you need mass and decoupling, such as added drywall or resilient channels. Treat this as an absorber and heat reflector, not a soundproofing wall.
- Which thickness should I buy?
- Use 5mm to 10mm for lining cabinets, car doors or ducts where space is tight. Go 20mm to 50mm for wall panels where you want more sound absorption and thermal buffer. Thicker sheets cost more and weigh more per square meter.
- How much area does one order cover?
- Each unit covers 1 square meter, roughly a 1m x 1m sheet. Measure your wall and add 10 percent for cuts and waste. A 3m x 2.5m wall needs about 8 units.
- Will the adhesive hold on a painted or dusty wall?
- It holds best on clean, smooth, dry surfaces. Wipe off dust and grease and let the wall dry fully before pressing the sheet down. On rough brick or loose paint, plan on extra mechanical fasteners or an adhesive primer.
- Is it fire safe?
- The listing describes it as flame-retardant and fireproof, but that is a material claim, not a certified rating. Ask the seller for the test standard before using it near stoves, flues or electrical panels.
- When is it cheapest?
- The best new price was $18.94 at eBay as of November 4, 2026. Thin sheets and multi-sheet bundles usually come in lowest per square meter, so compare price per unit rather than per listing.
