Also searched as acoustic roller shutter, sound-insulating rolling door and noise-control shutter.
An acoustic roller shutter that closes a noisy opening with a dense, sealed barrier — dense insulated slats, full-perimeter sealing and a tight bottom edge to cut sound transmission. Built to your opening and your target attenuation, from prototype to full production runs.
One idea: a rolling door that does the job of an acoustic wall — closing a wide opening with mass and airtight seals so plant noise stays inside the room.
Sound escapes through the weakest part of an enclosure, and a standard shutter is full of weak points: thin single-skin slats, leaking guides and a gap under the bottom bar. A soundproof roller shutter attacks all three. Dense, insulated slats add mass; sealed guide channels close the edges; and a compressing bottom seal takes up the floor gap — so the closed shutter behaves like a rated acoustic barrier rather than a thin metal skin.
RAX builds each acoustic shutter to your opening and your target sound reduction, matching slat construction and sealing to the attenuation you need. The achieved Rw is confirmed per project on the matching acoustic test data, because the installed result depends on the surrounding wall as much as on the door itself.
Sound reduction (Rw) figures shown are industry-typical ranges for acoustic shutters of this construction; the achieved value for your installation is confirmed per project on the matching acoustic test data, since the surrounding wall and sealing detail govern the result. Cycle life of 100,000 cycles is validated in the RAX fatigue test lab.
Every shutter is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification. Each row states whether the value is RAX-measured, an industry-typical range, or per project.

Need an Rw value evidenced for a noise assessment? We arrange the matching acoustic test data per project — see Compliance below for what is held versus arranged per project.
Validated substrates, processed in-house on an auto PU foam panel line and CNC punching / bending centre. No outsourcing of the structural parts.
Openings that need vehicle or equipment access but must not become a path for noise.
Your installers get the full document set before the shutter ships — the same package our EPC and distributor clients rely on.
Certificates we hold today, and the project-specific acoustic test data we arrange against the matching standard. We state held versus per-project so you can tender honestly.
Rigorous 100,000-cycle fatigue testing, validated galvanized steel materials, and precision manufacturing — performed in-house, with acoustic performance confirmed per project on the matching test data.
Large industrial doors from prototype to container-load delivery. Start with an OEM sample and scale to container-load branded production.
Every acoustic shutter is built to your opening and your target attenuation. Send the clear opening size, the required Rw and the duty (or site photos) and our engineers return a proposal, technical confirmation and lead time.
From custom engineering to container-load delivery — the document set your local installers need.
Warranty: door body 2 years · operator/motor 3 years · servo motor 5 years. Free spare parts within warranty (DHL/FedEx 5–7 days). Lead time: sample 7–15 days · standard container 12–20 days · custom first order 20–35 days.
Acoustic shutters of this dense, sealed construction typically achieve a sound reduction in the Rw 25–40 dB range, depending on slat mass and sealing detail. The achieved value for your installation is confirmed per project on the matching acoustic test data, because the surrounding wall and the perimeter sealing govern the final result as much as the door itself.
Three things: dense double-skin slats with acoustic infill add mass to block sound; sealed guide channels close the edge leakage paths; and a compressing bottom seal takes up the floor gap. A standard shutter has thin single-skin slats and open edges, so sound passes straight through. The acoustic version is engineered so the closed curtain behaves like a rated barrier.
Yes. The acoustic shutter accepts tubular or side-mounted motors with a RAX servo VFD drive, plus radar, geomagnetic or light-curtain activation and optional WiFi / RS485 remote control. A manual gear override is available for low-cycle or backup use. The acoustic sealing is maintained across all drive options.
Yes. Every shutter is engineered to your clear opening width and height, or from site photos. Every order is custom-manufactured, so you can buy a single shutter built to a non-standard size, in any RAL colour. Our engineers confirm the feasible span and produce a technical proposal for approval before production.
RAX holds ISO 9001:2015, CE marking against EN 13241 (industrial door product standard) and EN 12453 (operator safety), plus SGS material reports and Product Liability Insurance. The acoustic Rw value and AS/NZS 4505 / UL counterpart test data are arranged per project, not held as standing certificates.
Sample orders run 7–15 days, a standard container 12–20 days, and a custom first order 20–35 days (repeat custom orders 15–20 days). FOB ports are Tianjin and Qingdao; FCL and LCL are both supported.
Every order includes wiring diagrams, an English installation manual, FAI first-article confirmation and pre-assembly photos, a factory inspection report (speed, noise, insulation resistance, visual), the 100,000-cycle fatigue test video/report, and the CE Declaration of Conformity with the EN 13241 test report.
Send your opening size (W × H), the target sound reduction (Rw) and the duty. Our engineers reply with a proposal and lead time — no obligation.
