Certificate type
Natural twin flap roof ventilator, suitable for natural day to day ventilation and smoke control.
Application
Suitable for natural smoke control and provision of extract ventilation for most kinds of industrial and commercial buildings.
Description
Natural twin flap ventilator, suitable for natural smoke control and day-to-day ventilation.
Features and benefits:
- Wide range of applications: Firelight DUO 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 or electric linear drives 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. Manufactured under the ISO 9001 quality standard.
- Easy to install: 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: Manufactured from tough, corrosion-resistant aluminium, with stainless steel fixings.
Also tested in accordance with:
- 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, achieving 300 Joule with the polycarbonate version and 1200 Joule with the insulated aluminium version.
Also available as a single flap ventilator (Firelight FL2 or FL3); both specified separately.
