Firelight Duo 

The Firelight Duo is a dual-purpose natural ventilator providing both smoke control and day-to-day ventilation, while letting in natural light. Tested to EN 12101-2, it combines fully thermally broken construction with excellent acoustic insulation (up to 49 dB), high weather resistance (Class A9), and superior air tightness (Class 4). Available in sizes up to 2500 × 3000 mm with glass, polycarbonate, or aluminium infills, it offers flexible control options and a discreet low-profile design.

Product Highlights:

• Dual-purpose smoke and day-to-day ventilation with daylight entry.
• Fully thermally broken for improved energy efficiency.
• Acoustic insulation up to 49 dB for occupant comfort.
• Low-profile design – only 120 mm high when closed.
• Certified to EN 12101-2 and multiple window/door standards.
• Flexible sizes up to 2500 × 3000 mm in mm increments.
• Wide choice of glass, polycarbonate, or aluminium infills.
• Operated by pneumatic or electric actuators with control options.

Product Technical Information

Dimensions:

• Unit width: from 1000 mm to 2500 mm (in mm increments).
• Unit length: from 1000 mm to 3000 mm (in mm increments).

Panel Options:

• Polycarbonate: Transparent or opaque polycarbonate, 16mm or 25mm thick, or up to 50mm available on request
• Glass: As standard double 32 mm thick insulating glass or customized insulating glass up to 50 mm thick. Triple insulating glass can be used without any problems.
• Aluminium insulated panels: Outer skin 2 mm thick aluminium, polyurethane infill panel with a density of 30 kg/m³, thermal conductivity 0.030W/(mK), inner skin 2 mm thick aluminium. As standard 25 mm thick, available with other panel types available on request.

Thermal Performance (U value):

The Firelight Duo can achieve a U-Value of up to 1.01 W/m2 K depending on the variant selected. Please contact our technical team

Controls:

The Firelight Duo can be opened and closed either by double-acting pneumatic cylinders that lock in their ends positions, or by 24 V DC or 230 V AC electric actuators. A 230 V AC electric actuator offers the advantage over a 24 V DC electric actuator of a faster opening speed, as well as noticeably reduced wiring costs.
