Firelight Duo natural flap ventilator

Firelight Duo provides high performance extract ventilation for most kinds of industrial and commercial buildings, and has been designed with the ever more stringent demands of the Energy Performance in Buildings directive in mind. Tested to and in compliance with EN 12101-2.

Product information

Features and benefits

A wide range of applications - Firelight Duo is classed as a dual purpose ventilator, providing both day to day and smoke control ventilation. Polycarbonate and glass versions allow the entry of natural daylight, and a wide range of infill panels are available, including a reduced noise panel. Pneumatic or electric linear drives are available.

Proven performance - Firelight Duo has been exhaustively tested and certified to EN 12101-2: 2003 in accredited third party test laboratories and is CE marked.

High performance - Firelight Duo has high aerodynamic, acoustic and thermal performance, and has a high resistance to the effects of fire.

Acoustic performance – Firelight Duo offers a reduced noise panel with a performance of 49 dB R’w.

Thermal performance - Firelight Duo is thermally broken and has five high grade continuous EPDM and TPE seals, two which seal the panels into the lids and three between the lids and the frame. As a result there is very low air leakage and a low U-value.

In addition to this the Firelight Duo has been tested in accordance with typical window and door standards:

EN 12207: Air permeability

EN 12208: Water tightness

EN 12211: Resistance to wind load

An impact test has been carried out on the Firelight Duo in accordance to GSBau18. We achieved 300 Joule with the polycarbonate version and 1200 Joule with the insulated aluminium version.

Easy to install - Firelight Duo is designed for installation into glazing, onto a curb or into sheeting. It has a wide range of base profiles to suit most glazing, sheeting or curb types.

Durable - Firelight Duo is manufactured from tough, corrosion resistant aluminium with stainless steel fixings.

Quality of manufacture - Firelight Duo is manufactured under the ISO 9000 quality standard.

Options

Description

Natural twin flap roof ventilator, suitable for natural day to day ventilation and smoke control, for high aerodynamic, acoustic, airtightness and thermal performance. Tested to and in compliance with EN 12101-2 and CE marked. Classified as fall through resistant when closed in 300J & 1200J impact tests. Manufactured under the ISO 9001 quality standard.

Dimensions / size range

  • From 1000 mm to 2500mm overall ventilator width in 1 mm increments (to 2000mm with bracket control option)
  • From 1000mm to 3000mm overall ventilator length in 1 mm increments.

Flap options

  • Double or triple glazed: 28, 30 or 32mm overall thickness or customer specified (up to 60 kg/m²)
  • Polycarbonate: 16 or 25mm overall thickness or customer specified (from 16 up to 50 mm), either clear or opaque
  • Infill panel: a 2mm thick aluminium external sheet, 25mm thick infill with a mass of 30 kg/m2 and heat transfer of 0.03 W/m²K, 2mm thick internal sheet. 25mm overall thickness as standard.
  • Noise reduction panel, multi-layer system to achieve R’w of 49 dB.

Wind baffle

  • Without wind baffles
  • With wind baffles on two sides to improve aerodynamic performance

Materials

All components of the base and flap are manufactured from EN AW 6060-T66 aluminium alloy. The frames of both the base and flap are thermally broken.

Colours/ finishes options

  • Mill finish, standard
  • Polyester powder paint to a RAL colour, standard 75 mu

Fixing options

  • Fixing flange for curb
  • Fixing flange for glazing
  • Fixing flange for roof sheeting

Installation angle from 0 to 10° from the horizontal.

Controls options

  • Pneumatic
  • 24V DC linear drive electric

Both options are for smoke and day to day ventilation. For pneumatic versions, either double-action locking mechanisms or fail safe open. For electric versions, only double-action locking option available.

  • Bracket controls (for smaller vents and/or those installed into glazing)
  • Control channel controls (for larger vents and/or heavier lids or need to keep actuator lengths short)

If it is used as a smoke ventilator, activation is either by local thermal fuse which opens the unit at a pre-selected temperature, or by responding to an external release signal.

Performance

Performance

The following performance attributes follow tests to EN 12101-2 (standard for smoke and heat exhaust ventilators). The exact performance attribute will depend on the chosen size, controls, and flap type.

Compliance

Classified as fall-through resistant when closed in accordance with “GS Bau 18”, achieving resistance to 300 Joules with the polycarbonate version and 1200 Joules with the insulated aluminium version.

An impact test has been carried out on the Firelight Duo in accordance to GSBau18. We achieved 300 Joule with the polycarbonate version and 1200 Joule with the insulated aluminium version.
