Acoustic Roller Shutter

SilentRoll® 45/50dB

Dual-Layer Acoustic Roller Shutters (Rw 45-50dB)

Model Reference: SD-RSD45/50

SilentRoll® 45 & SilentRoll® 50 – High-Performance Acoustic Roller Shutters


For environments demanding maximum noise reduction, the SilentRoll® 45 and SilentRoll® 50 acoustic roller shutters offer industry-leading sound insulation, reducing noise transmission by up to 45dB and 50dB (Rw), respectively. These heavy-duty soundproof shutters are ideal for industrial sites, manufacturing plants, testing facilities, and high-security areas where superior acoustic performance is essential.

Built with a dual-layer galvanised steel construction, integrated soundproofing materials, and a two-barrel roller system, these shutters provide exceptional durability, strength, and acoustic control.


Key Benefits:

✔ Industry-leading noise reduction of up to 50dB for high-noise environments.
✔ Dual-layer galvanised steel with integrated acoustic dampening.
✔ Two-barrel system for enhanced structural stability and performance.
✔ Heavy-duty electric operation with manual override for emergency access.
✔ Precision-engineered seals to minimise sound leakage and enhance insulation.


Whether you need high-performance acoustic control for industrial, commercial, or specialist applications, the SilentRoll® 45 & 50 deliver unmatched soundproofing, security, and reliability.


✅ Enhanced Acoustic Insulation

  • Rw 45dB – 50dB sound reduction (ISO 140-3 tested).
  • Dual-layer roller shutter system with a minimum 645mm air gap for optimal noise control.
  • 1.25mm thick hot-galvanized steel panels, filled with acoustic-grade mineral wool.
  • Double-sealed lintel system to minimize airborne sound leakage.
  • Side guides with integrated sealing strips for superior noise reduction.
  • Additional absorption lining (SilentRoll® 50 only), featuring perforated steel panels and mineral fiber damping to further enhance sound insulation.


✅ Heavy-Duty Construction & Safety Features

  • Two independent roller barrels made of pre-coated steel for enhanced stability and durability.
  • Pre-galvanized steel bearing brackets for long-term reliability.
  • Integrated hollow-chamber damping within the side guides for added soundproofing.
  • Impact-resistant T-steel bottom rails with an IP65-rated electrical safety edge for door movement monitoring.
  • Safety monitoring electronics with optical fault indication.
  • Drive chains with a 6x safety factor against breakage (for chain-driven versions).
  • Protective covers for chain-driven models installed below 2.5m.


✅ Powerful Motor System

  • Two synchronized electric drives (60% duty cycle, IP54-rated).
  • 3~400V AC / 16A power connection, 50Hz.
  • Direct-coupled worm gear system with spring-applied brake for precise control and emergency stopping.
  • Built-in anti-fall safety system (EN 12604 compliant).
  • Manual override crank with safety interlock for backup operation.


✅ User-Friendly Control Unit

  • IP54-rated control panel in a robust plastic casing.
  • Up-Stop-Down keypad integrated into the control box.

Installation & Operational Considerations


🚧 Maximizing Acoustic Performance
To achieve the highest soundproofing efficiency, building acoustics must complement the shutter's performance:

  • Walls and surrounding structures should have an Rw rating matching or exceeding the door.
  • Floor sealing should be acoustically decoupled (e.g., using an elastic joint instead of continuous screeds).


⚡ Power & Safety Requirements

  • Requires 400V / 16A three-phase power supply with a CEE socket near the control panel.
  • Optional emergency stop switch available upon request.


🛠 Surface Wear Disclaimer

  • Normal operation may cause minor surface wear on the shutter and guide rails.
  • Degree of wear depends on frequency of use, weight load, and environmental factors.
  • This does not impact functionality and is considered a standard characteristic of rolling shutter systems.


The SilentRoll® 45 & SilentRoll® 50 deliver industry-leading noise reduction while ensuring robust performance, high security, and smooth operation, making them the ultimate choice for environments requiring strict acoustic control.
