Suitable for natural smoke control and provision of extract ventilation for most kinds of industrial and commercial buildings.

Suitable for natural smoke control and provision of extract ventilation for most kinds of industrial and commercial buildings.

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.

Certification + Test Results:

• Tested and is certified to EN 12101-2.
• EN 12207 – Air permeability: Class 4.
• EN 12208 – Resistance to weather: Class A9.
• EN 12211 – Wind loads: Class C5.

Acoustics:

Up to 49 dB.
