Hörmann Decotherm SB: The Evolution of the Insulated Roller Door

The Hörmann Decotherm SB (Spring Balanced) is a revolutionary insulated roller shutter that bridges the gap between industrial durability and manual ease of operation. Unlike traditional heavy roller shutters that rely solely on powerful motors or cumbersome chain hoists, the Decotherm SB utilizes an innovative tension spring assembly to counterbalance the door curtain's weight perfectly.

This unique engineering allows for a door that is not only effortless to operate by hand but also exceptionally smooth and durable when electrically automated. Featuring the robust "Decotherm S" double-skinned steel laths with PU-foamed infill, this door provides excellent thermal insulation and stability while maintaining a compact, space-saving design.

The "SB" Difference: Innovative Tension Spring Balancing

The core innovation of this door is its patented tension spring assembly. This system sets the Decotherm SB apart from standard roller shutters by effectively neutralizing the weight of the door curtain.

• For Manual Operation: The springs do the heavy lifting, allowing you to open and close door sizes up to 5000mm wide and 4500mm high manually with minimal effort using the interior handle or pull cord.
• For Electric Operation: The springs relieve the mechanical stress on the operator (motor) and drive components. This significantly extends the service life of the operator and ensures a smoother, quieter run.

Versatile Operation Modes

1. Effortless Manual Operation

Designed for low-frequency openings or buildings where power supply is limited, the manual Decotherm SB is a cost-effective solution.

• Simple Handling: Operated via a robust interior handle or pull rod.
• No Chain Hoist Needed: The spring balance means there is no need for slow, heavy chain mechanisms often found on industrial doors.
• Secure: Includes lockable bottom profiles and shootbolts for security.

2. Advanced Electric Automation (WA 300 Series)

When paired with the WA 300 R S4 or WA 300 AR S4 operators, the Decotherm SB offers a "soft start" and "soft stop" action that is incredibly gentle on door components.

• Cost-Saving Safety Tech: Because the spring assembly limits the power required to move the door, most sizes do not require a closing edge safety device or lintel trap guard. This eliminates the need for wear-prone spiral cables and sensitive bottom sensors, reducing long-term maintenance costs and failure points.
• Compact Installation: The WA 300 AR S4 operator can be installed in tight spaces (requiring only 100mm additional sideroom), making it ideal for shop fronts or areas with intermediate ceilings.

Key Features & Benefits

• Space-Saving Design: Requires only 165mm of sideroom, making it one of the most compact industrial roller doors available, perfect for fitting in tight spaces.
• Thermal Efficiency: The "Decotherm S" profile features special concave/convex surfaces for tight winding and PU-foam filling for thermal and acoustic insulation.
• Wind Load Resistance: Rated for Wind Load Class 4 (up to 12m widths with specific packages), ensuring stability in exposed locations.
• Low Maintenance: The omission of complex safety sensors and the reduced strain on the motor means fewer service call-outs and lower running costs over the door's lifetime.

Domestic, commercial and industrial applications where there is a need for higher performance from a roller shutter door. Smaller to medium sized openings up to 5m x 4.5m.

This is one of the more simple roller door for installation by non professionals with a simple sring balancing feature to one side.
it would require at least 2 persons and lifting euqipment for the barrel and curtain over certian sizes.
