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.
1. 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.
2. Self-adhesive backing means no drilling, no contractor, no damage when you peel them off later.
3. 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 Weather Strip (KK1154) to close drafts and high-frequency leaks around the door perimeter. Most customers buy both together.
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.
Weather strip and tools sold separately. See the "Frequently Bought Together" section above to add them at a discount.
No drill. No nails. No contractor.

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.
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.
Yes. Use scissors or a utility knife. The polyester fiber cuts cleanly without fraying.
Designed for clean removal on most interior doors. We recommend a 24-hour test patch in a hidden corner first.

I train dogs out of my house. I ordered two door kits because on the other side of my door is a rental apartment. I don't want my renter to be bothered by the dogs barking. Easy to install. So far, it is working out well. Looks pretty good too.
Got exactly what I paid for. Nice clean cuts as well. Easy to install because of the adhesive on the back.
Our basement is a multi-use space, and this soundproofing kit has been perfect for reducing the noise that travels upstairs. Installation was easy, and the noise reduction is impressive.
I have big door gaps for my apartment and the tape works like a charm. The adhesive was easy to apply. No nasty plastic smell. It was easy to trim and good fit for my door.
