Hormann DD S6 Decotherm S High-Speed Insulated Roller Shutter

The Robust Alternative to Fabric High-Speed Doors

The Hormann DD S6 Decotherm S bridges the gap between traditional security shutters and modern high-speed doors. Designed for busy industrial openings, it combines the security and thermal efficiency of a double-skinned steel roller shutter with the rapid performance usually associated with PVC fabric doors.

For facilities where energy loss, security, and speed are all critical priorities—such as external loading bays or busy logistics corridors—this door offers a "best of both worlds" solution in a single, durable package.

High-Speed Performance with S6 Motor

Unlike standard roller shutters that operate slowly, the DD S6 is powered by a high-performance S6 motor and frequency converter package. This advanced drive system achieves opening speeds of up to 1.1 m/s, allowing forklifts and vehicles to pass through without delay. The integrated soft-start and soft-stop technology significantly reduces mechanical stress on the door components, ensuring a long service life even in high-cycle environments like factories and warehouses.

Superior Insulation and Security

The curtain is constructed from Decotherm S double-skinned steel laths filled with rigid polyurethane (PU) foam. This design provides:

• Thermal Efficiency: Minimises heat loss in winter and keeps cool air inside during summer, far outperforming single-skin shutters.
• Acoustic Insulation: Noticeably reduces noise transfer between internal and external zones.
• Enhanced Security: The rigid steel curtain resists forced entry, while heavy-duty wind locks in the guide channels keep the door secure against storms and high wind pressure.

Compact and Easy to Retrofit

Space is often at a premium in industrial buildings. The DD S6 system is engineered to require only modest headroom compared to standard shutters, and significantly less space than bulkier spiral doors. Its pre-engineered components and compact operator make it an ideal choice for retrofitting into existing openings where a standard shutter is too slow or a fabric door offers insufficient security.

Smart Safety Features

Modern safety standards are built-in. The door features an integrated light grille or advanced safety sensors within the side guides. This creates a non-contact safety zone that detects obstructions instantly, removing the need for vulnerable safety edges on the bottom of the door. The control panel supports partial opening settings and traffic light interfaces, allowing seamless integration into automated building systems.

Busy External Loading Bays

For goods-in areas that see frequent forklift traffic, standard shutters are too slow and fabric doors lack security. The DD S6 Decotherm S offers the perfect middle ground: fast access during the day for efficiency, and a secure, insulated steel lock-down at night.

Energy-Critical Warehouses

In temperature-controlled environments, leaving a door open for even a few extra seconds wastes significant energy. The rapid 1.1 m/s opening speed, combined with the insulated PU-foam core, minimises air exchange and helps maintain stable internal temperatures.

High-Security Logistics

Facilities storing high-value goods need more protection than a PVC curtain can provide. The robust double-skinned steel curtain of the Decotherm S provides a formidable physical barrier against forced entry, without sacrificing the speed needed for modern logistics operations.

Production Halls

Where noise and dust control are important, the insulated curtain acts as an effective sound barrier. Its smooth, quiet operation improves the working environment for staff located near large access doors.

 ● = Standard   ◌ = Optional

For the purposes of pricing we require the width and height of the daylight opening, but also the inside return dimensions either side of the opening and the headroom above the lintel. Most roller shutter doors are installed to the inside face of any opening to maximise width and height and to keep the side guides and curtain roll out of the way, but is is always possible to install a roller door inside, inbetween, or outside and opening if required.
