Hormann HR120 Aero Roller Shutter
The Hormann HR120 Aero is a premium perforated roller shutter solution engineered for high-visibility security applications. Unlike standard open grilles which allow debris to pass through, the HR120 Aero uses a finely perforated aluminium profile (approx. 30% free area) that acts as a secure screen. This makes it particularly suitable for underground car parks where ventilation is mandatory for exhaust extraction, but protection against wind-blown litter and unauthorised access is equally critical.
Profile Technology & Safety
The shutter curtain is constructed from single-skinned, concave aluminium profiles with fine perforations. This smart design offers dual benefits:
- Climb Resistant: The smooth, concave shape makes it virtually impossible for children or intruders to gain a foothold or climb the shutter, significantly reducing injury risks and enhancing security.
- Visual Contact: The perforations provide a "see-through" effect when back-lit, allowing security personnel to view the secured area without opening the door.

The Hormann HR120 Aero requires professional installation due to its specialised perforated profile and precise tensioning requirements. Installation procedures vary significantly between the compact SB system and the heavy-duty Classic system.
SB Rolling Shutter (Compact Applications)
The SB system features a unique tension spring assembly that simplifies installation while reducing sideroom requirements:
- Pre-Assembled Components: The SB system often arrives with pre-assembled components to speed up site work.
- Tension Spring Balancing: The integrated tension springs counterbalance the door weight, making manual operation effortless and protecting the electric motor (if fitted) from excessive wear.
- Reduced Sideroom: Typically requires less sideroom (approx. 165mm bearing side / 100mm non-drive side) compared to traditional industrial shutters, making it easier to fit in tight spaces.
- Low Headroom: The innovative spring system allows for a smaller lintel requirement (approx. 450-580mm depending on height).
Classic Rolling Shutter (Large Applications)
For large openings up to 11.75m wide, installation is a heavy-duty operation requiring mechanical lifting equipment:
- Mechanical Lifting: The barrel and curtain weight for large Classic shutters necessitates a forklift or scissor lift for safe positioning.
- ZAK® System Option: On Classic shutters, the optional ZAK® gear system moves the barrel horizontally as the door operates. This keeps the curtain entering the guides vertically, reducing friction, noise, and wear—critical for the longevity of perforated profiles.
- Electrical Supply: Large Classic systems typically require a 3-phase (400V) power supply for the direct drive motor.
General Fitting Requirements
- Structural Fixing: The guide rails and brackets must be fixed to a structural substrate capable of supporting the dynamic loads (wind and operation).
- Level Floor: A level floor is essential for the bottom profile to seal correctly and for the locking mechanism (if fitted) to engage.
- Safety Compliance: All electric installations must be commissioned by a qualified engineer to set limits and safety edge devices in accordance with BS EN 13241-1 standards.
Measuring Guide
Precision is paramount. The Hormann HR120 Aero is a fully bespoke roller shutter system, manufactured to order in Germany. Unlike standard shutters, there are no "stock" sizes. Every millimeter counts to ensure the curtain, guides, and drive system fit your specific aperture perfectly.
Why Professional Measuring is Crucial
Due to the complex engineering of the HR120 Aero—particularly the tension spring assembly on the SB model and the ZAK® system on the Classic model—inaccurate measurements can lead to significant installation failures. Given the manufacturing lead times from Germany, errors are costly and time-consuming to rectify.
Critical Dimensions to Record
When preparing for a quotation or order, you must ascertain the following structural dimensions:
- Structural Opening Width (Daylight Width): Measure at the top, middle, and bottom. The shutter is typically manufactured to the Ordering Size, which corresponds to the final guide width (Daylight Width + Guide Widths).
- Structural Opening Height (Daylight Height): Measure from the finished floor level to the underside of the lintel at the left, centre, and right.
- Headroom (Lintel Space): This is the clear space above the opening where the coil and mechanism will sit.
- SB System: Requires approx. 450mm - 580mm depending on height.
- Classic System: May require significantly more headroom (up to 900mm+) depending on the curtain height and rolling diameter.
- Sideroom (Left & Right): The clear space required on either side of the opening for guides and drive mechanism.
- SB System: Very compact, typically needing only ~165mm on the bearing side and ~100mm on the non-drive side.
- Classic System: Requires larger sideroom for the direct drive motor and potential ZAK® system displacement.
Determining the Installation Type
Your measurements will dictate the final "Ordering Dimensions" based on how you intend to fit the shutter:
- Face Fix (Internal/External): The guides and coil sit outside the structural opening. This maintains the full clear passage width but requires sufficient sideroom and headroom.
- Reveal Fix (Between Jambs): The shutter sits inside the opening. This reduces the drive-through width and height but is necessary when no face-fixing surface is available.
