Natural casement roof single flap ventilator, suitable for natural smoke control and day-to-day ventilation.
Application
Suitable for natural smoke control and provision of extract ventilation for most kinds of industrial and commercial buildings.
Particularly suited for installation into glazing systems.
Description
Natural casement roof ventilator, suitable for natural smoke control and day-to-day ventilation.
Features and benefits:
- Wide range of applications: Firelight is classed as a dual-purpose ventilator. Polycarbonate and glass ventilation versions allow the entry of natural daylight, and a wide range of infill panels are available.
- Pneumatic, electric linear, electric chain or electric tubular fail safe drives or hand controls are available.
- High aerodynamic, acoustic and thermal performance, and has a high resistance to the effects of fire.
- Exhaustively tested and certified to EN 12101-2: 2003 in accredited third-party test laboratories and is CE marked. Tested and certified according to EN 14351. Manufactured under the ISO 9001 quality standard.
- Easy to install: delivered fully assembled to site. May be installed at any angle from the horizontal to the vertical (0–110º) onto a curb, into sheeting or into glazing.
- Wide range of base profiles to suit most sheeting, curb or glazing applications.
- Durable: Manufactured from tough, corrosion-resistant aluminium grade 6063-T6 alloy, with stainless steel fixings.
- Low profile and slim frames.
Also available as a single flap ventilator with high aerodynamic, acoustic and thermal performance (Firelight FL3) or as a double flap ventilator (Firelight Duo); both specified separately.
