Firelight natural flap ventilator

Colt Firelight is a natural casement roof ventilator, suitable for natural smoke control. It has high aerodynamic, acoustic and thermal performance, providing extract ventilation for most kinds of industrial and commercial buildings. It is particularly suited for installation into glazing systems. Firelight conforms to EN 12101-2 and is CE marked. Firelight is manufactured under the ISO 9001 quality standard.


  • Single flap with centre controls
  • Single flap with side controls
  • Chain drive (mechanism within the frame)
  • Tubular drive with gas springs

Dimensions / size range

  • From 700mm to 2500mm in width in 1mm increments.
  • From 700mm to 2500mm in length in 1mm increments.

These are the maximum overall ventilator sizes:

  • 2.64m² with one pneumatic cylinder
  • 5m² with two pneumatic cylinders
  • 3m² with one 24V DC actuator
  • 5m² with two 24V DC actuators

These dimensions depend upon the type of flap, the geometry of the ventilator and its opening angle.


All components of the base and flap are manufactured from EN AW-6063 T6 aluminium alloy. 

Flap options

  • Double glazed
  • Polycarbonate
  • Infill panel either from insulated or uninsulated aluminium

Glazing and panels are between 7 and 35mm in thickness with a standard of 32 mm.


All components of the base and flap are manufactured from EN AW-6063 T6 aluminium alloy. The frames of both the base and flap are thermally broken.

Colours/ finishes options

  • Mill finish, standard
  • Polyester powder painted to a RAL colour, standard 70 µm
  • Anodised, standard 20 µm

Fixing options

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

Fixing flanges are between 8 and 34mm.
Installation angles are from 0º to 110° from the horizontal.

Controls options

  • Pneumatic
  • 24V DC linear drive electric
  • 24V DC chain drive electric
  • 230V AC electric fail safe
  • Manual (for day to day ventilation only)

For both electric and pneumatic versions, double-action locking mechanisms. For electric and pneumatic version, fail safe open (only the pneumatic version has been tested to EN 12101-2).

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


The following performance attributes follow tests to EN 12101-2:2003 (the standard for smoke and heat exhaust ventilators). The exact performance attribute will depend on the chosen size, controls, and flap type.

  • Aerodynamic coefficient: Up to 0.64
  • Reliability: RE 1000 (10,000 cycles)
  • Wind load: up to 2000 N/m²
  • Snow load: up to 2000 N/m²
  • Resistant to heat: B 300
  • Low temperature class: T(00) to T(-15)
  • Materials resistance to fire: E (to EN 13501-1)
  • U value: up to 1.6 W/m²K
  • Air permeability: Class 3 - Maximum of 9m3/hr/m² or 2.25m³/hr/m at 100Pa (to EN 12207:1999)
  • Water tightness: Class 9 A - No leaks at static pressure of up to and including 600Pa (to EN 12208:1999)
  • Sound insulation: (R'w) 40 dB R’wCompliance


Tested to and in compliance with EN 12101-2 and CE marked.
