Application

Can provide inlet and extract ventilation as well as the entry of natural daylight for most kinds of industrial and commercial buildings. Suited for installation into the facade.

Typical applications are hospitals, schools, shopping centres, apartments and commercial buildings.

Description

Natural louvred glazed ventilator, suitable for natural day-to-day ventilation and smoke control.

Its form and function makes it particularly suited to naturally ventilated buildings where good aerodynamic and measured free area ventilation is required while achieving high acoustic, thermal and aerodynamic performance. Whilst it is primarily designed as a glazed element of the building envelope, it can also be applied as a high specification fire, smoke and air control damper.


Features and benefits:

  • CE marked.
  • Most variants conform to both EN 12101-2 as smoke ventilators; all models conform to EN 14351-1 as natural ventilators.
  • It can provide inlet and extract ventilation as well as the entry of natural daylight for most kinds of industrial and commercial buildings.
  • Achieves high acoustic, thermal and aerodynamic performance.
  • Suited for installation into the facade.
  • Easy to install.
  • Safe in operation.
  • Durable: manufactured from tough, corrosion resistant aluminium alloy, with stainless steel fixings.
  • Manufactured under the ISO 9000 quality standard.
  • Aesthetic design.
