SilentRoll® 25dB

Model Reference: SD-RSD25

SilentRoll® 25 – Acoustic Roller Shutter for Moderate Noise Reduction

The SilentRoll® 25 is a versatile sound-insulated roller shutter, designed to reduce noise transmission by up to 25dB (Rw). Ideal for commercial units, workshops, storage facilities, and industrial environments, this shutter provides a balance of soundproofing, security, and durability.

Constructed from hot-galvanised steel and infilled with 20mm PUR foam, the SilentRoll® 25 effectively minimises sound leakage while offering smooth electric operation with a manual override for emergency access.

Key Benefits:

✔ Reduces noise transmission by up to 25dB,  enhancing workplace comfort.
✔ Durable galvanised steel with integrated acoustic insulation.
✔ Precision-engineered side guides with rubber sealing for improved soundproofing.
✔ Reliable electric drive system with emergency hand-crank operation.
✔ Weather-sealed construction,  ensuring long-lasting performance.

The SilentRoll® 25 is an ideal solution for medium-noise environments where effective sound control is required without compromising on security and durability.

Fun Fact

Did you know that two SilentDoor RW® 35T doors together achieve a sound reduction of 38dB? In comparison, a single SilentDoor RW® 40T door would provide even greater impact.

Installation & Maintenance Considerations

🚧 Building Acoustics Matter
The SilentRoll® 25 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® 25 is a high-performance acoustic roller shutter that combines sound insulation, durability, and ease of use—an excellent choice for businesses that require noise control without compromising security or reliability.
