Acoustic Roller Shutter

SilentRoll® 31dB

Enhanced Acoustic Roller Shutter (Rw 31dB)

Model Reference: SD-RSD31

SilentRoll® 31 – Acoustic Roller Shutter (Rw 31dB)


The SilentRoll® 31 is a high-quality acoustic roller shutter, engineered to reduce noise transmission by up to 31dB (Rw). Designed for industrial, commercial, and high-traffic environments, it provides superior sound insulation, making it ideal for warehouses, workshops, recording studios, and commercial facilities.


Crafted for durability and reliability, this soundproof rolling shutter features a hot-galvanised steel construction with a mineral wool infill, ensuring enhanced acoustic performance while maintaining strength and security.


Key Benefits:

✔ Superior noise reduction for medium-noise environments.
✔ Durable steel design with integrated acoustic dampening.
✔ Smooth electric operation with manual override.
✔ Weather-sealed side guides for added protection.


The SilentRoll® 31 is the perfect sound insulation solution where noise control, durability, and security are essential. Contact us today to discuss


✅ Advanced Sound Insulation

  • Reduces noise by up to 31dB (ISO 140-3 tested).
  • Constructed from 1.25mm thick hot-galvanised steel with a clear protective coating for enhanced longevity.
  • Mineral wool infill provides superior sound absorption and thermal insulation.
  • Sealed side guides and lintel rubber lips for effective noise containment.


✅ Robust & Weather-Resistant Design

  • Wind load class 2 (EN 12424) for resilience against moderate wind pressure.
  • Side guides with multi-layer rubber sealing to minimise sound leakage and provide a secure fit.
  • Prime-painted steel bearing brackets for long-term structural support.


✅ Reliable Motorised Operation

  • Directly coupled electric drive (3/N/PE ~ 400 V 50 Hz) with an integrated safety arrestor (EN 12604 compliant).
  • Emergency hand-crank for manual operation during power failures.
  • Control unit (190x300x115mm) with integrated keypad for simple up-stop-down functionality.
  • Dead man’s control system (self-hold function available for door heights over 2.5m).
  • IP54-rated protection, ensuring reliability in industrial environments.

Installation & Maintenance Considerations


🚧 Building Acoustics Matter
The SilentRoll® 31 delivers its full acoustic performance only when installed in a suitable environment. To prevent sound leakage:

  • The surrounding walls must provide at least the same sound insulation rating as the shutter.
  • The best acoustic seal at the floor level is achieved through elastic decoupling, such as using an acoustic break in the flooring (avoiding continuous screeds or flooring materials).



⚡ Power Requirements

  • Requires a 400V / 16A three-phase power supply with a CEE socket near the control unit.
  • An optional lockable main switch is available instead of the CEE plug (upon request).


🛠 Surface Wear Disclaimer

  • Due to the rolling mechanism, abrasion marks may appear on the shutter surface and within the guides over time.
  • The extent of wear depends on profile type, weight, frequency of use, and environmental factors.
  • These marks are a normal part of operation and do not indicate a defect.


The SilentRoll® 31 offers an ideal balance of sound insulation, durability, and operational safety, making it the perfect choice for noise-sensitive environments that require secure and efficient access solutions.
