How the kit works
Door noise has two enemies: the door panel itself, and the gaps around the frame. This kit handles the panel, the bigger of the two surface areas and the part most people ignore.
High-density polyester panels (200 kg/m³) bond directly to the door surface. They absorb mid-to-high frequencies inside the room and add mass to the door to reduce sound transmission both ways.
Self-adhesive backing means no drilling, no contractor, no damage when you peel them off later.
Trim-to-fit design works on any standard interior door, hollow-core or solid, single-side or both sides.
Result: a measurable drop in noise within 20 minutes of opening the box.
Want to seal the frame gaps too? Add our to close drafts and high-frequency leaks around the door perimeter. Most customers buy both together.
What the numbers mean NRC 0.85 — Absorbs 85% of the sound that hits the panel. Your room sounds calmer, less echoey, better on calls.
STC 25-30 — Reduces conversational noise coming through the door by roughly 50-60%. Normal speech in the hallway becomes a low murmur.
Honest note: Panels alone will not fully block bass, drumming, or shouting. For maximum reduction, pair with the Weather Strip add-on and treat your walls and ceiling.
ASTM E84 Class A — Highest US fire-rating tier for interior finish materials. Same class accepted in commercial buildings, hotels, and recording studios.
What's in the box No drill. No nails. No contractor.

Frequently asked questions Will this stop a noisy neighbor? Partially. STC 25-30 cuts conversation-level noise by roughly 50-60%. It will not block bass or shouting on its own. For maximum reduction, add the Weather Strip and treat your walls and ceiling.
Does this kit include the weather strip? No. The kit includes acoustic panels only. The Weather Strip (KK1154) is sold separately and seals the gap between the door and the frame. Most customers buy both together for full coverage.
Can I cut the panels to fit my door? Yes. Use scissors or a utility knife. The polyester fiber cuts cleanly without fraying.
Will the adhesive damage paint or wood when I remove it? Designed for clean removal on most interior doors. We recommend a 24-hour test patch in a hidden corner first.
How many doors does one kit cover? 2 to 3 standard 80×36 inch interior doors, depending on whether you choose Single-Sided (20 panels) or Double-Sided (40 panels) and your layout.
Does it work on hollow-core doors? Yes. Hollow-core doors actually benefit most because the panels add the mass they're missing.
Does it work on glass doors? Yes, on the opaque sections. Avoid covering vision glass.
Is it renter-safe? Yes. No drilling, no permanent adhesive damage on standard interior finishes.
Will it smell? No. The panels are polyester fiber, not foam. No off-gassing complaints in 350+ verified reviews.
Is it fire-safe? Yes. ASTM E84 Class A in the US, the highest tier for interior finish materials. Equivalent to GB B1 / E1 standards in China.
Should I also do my walls and ceiling? For full room treatment, yes. The door is the highest-leverage starting point. See our Room Kit collection for full-room bundles.
Shipping? Ships in 1 business day. Delivers in 5-12 days depending on your location.
Returns? 60-day quiet-room guarantee on the kit. Defective or damaged items replaced free of charge.
