Large roof lanterns and expansive skylights create breathtaking spaces. But without proper shading, they can become unusable during peak sunlight or colder nights. The Hercules XL system is engineered to reclaim comfort and usability in oversized glazed areas, without compromising on aesthetics or performance.
Single blind spans up to 4m wide by 7m. Ideal for large-format roof lanterns and roof glazing.
Designed for scale without sacrificing the structural opening
Over 80kg of tension which is more than 8x the force of standard CTS systems.
Ensures a tauter fabric finish, defying gravity with much less sagging.
Robust spring and pulley system maintains consistent tension across the full width.
Smooth, reliable operation even at maximum dimensions.
Specially selected fabrics resist heat deformation and maintain alignment even under immense tension. This is essential for high-exposure glazed environments.
Install with or without Blindspace boxes for a clean, integrated appearance.
Bespoke, made to measure, to suit your build and design preferences.
Powered by the Altus 50 motor. Mains only.
Delivers the torque required for large blinds coupled with seamless automation.
Compatible with home automation systems for effortless control.
Integrates with Somfy RTS and hardwired setups.
Concealed integration for a hidden appearance when retracted.
Headbox sizes containing fabric tube, tensioning spring assembly and motor.
125mm wide × 125mm high for blinds up to 5m long
145mm wide × 180mm over 5m long
80mm side shelving makes a neat perimeter for the Hercules to squarely sit in for a uniform appearance.
Hercules XL is the pinnacle of oversized electric roof blind engineering. Created for vast roof lanterns and expansive skylights, it brings control, comfort, and usability back to spaces that were once overwhelmed by heat, glare, or cold. Designed for scale without compromise, Hercules XL delivers immense tension, flawless stability, and architectural integration that feels effortless.
With precision mechanics, dimensionally stable fabrics, and the torque to move serious weight, Hercules XL doesn’t just shade large spaces, it transforms them. More than a blind, it’s a structural solution that makes even the biggest glazed areas beautifully comfortable, day and night.
Hercules XL is bespoke built for large-format roof lanterns and expansive skylights. It reclaims comfort in oversized glazed areas by managing heat, glare, and cold without compromising aesthetics or usability.
Each blind can span up to 4m wide by 7m long, with the potential to go larger, making it ideal for substantial architectural openings.
Over 80kg of fabric tension more than 8x stronger than standard CTS systems
Robust spring and pulley mechanics for consistent tension across the full width
Dimensionally stable roller fabrics that resist heat deformation and sagging
Powder-coated aluminium headbox and shelving for a clean, integrated finish
The cords can stretch slightly over time due to the immense tension applied to them which will reduce the fabric tension.
Its advisable to have the Hercules XL electric roof blind serviced, to ensure the spring mechanism is at its optimal fabric tension. Just like it is when first installed.
Yes. Hercules XL offers flexible concealment options, including Blindspace integration or bespoke concealment at at 1st fix.
If installed into a completed upstand then headbox, side & end shelving are powder-coated for a seamless appearance.
It uses the Somfy Altus 50 mains-powered motor, delivering the torque needed for large blinds with smooth, automated operation.
Absolutely. Hercules XL integrates with Somfy RTS and hardwired automation setups, making it easy to control via home automation platforms such as Control 4 or Somfy Tahoma Switch
125mm × 125mm for blinds up to 5m
145mm × 180mm for blinds over 5m
These headboxes can be powder coated to any RAL Classic colour but standard is RAL 9016 traffic white.
The side & end shelving creates a neat perimeter for the blind to sit flush within the opening, ensuring a uniform and refined appearance.
It ensures that ‘out of square’ lantern upstands can be neatly compensated for.
It closes off light gaps that also helps stop flies entering the lantern.
The high performance fabrics are used to improve comfort beneath large glazed areas.
Selected correctly they combat excessive summer heat gain, winter drafts, TV glare, Room Darkening (near blackout) & allow natural light to be managed.
