Rooflights

Rooflights have long been recognised as an efficient means of bringing natural light to the interior of a building. In addition overhead daylighting and natural ventilation bring benefits in the form of a reduction in carbon emissions and running costs allowing designers the opportunity to develop more environmentally friendly buildings. Automatic opening vents (AOV) are an effective means of protecting occupants escaping from a fire, allowing cool air into a building and smoke and hot air to flow out.

For daylighting, roof access, ventilation and smoke evacuation

Axter has been manufacturing a complete range of rooftop equipment for natural daylighting, ventilation and smoke evacuation for over 50 years. Offering robust galvanised steel kerbs or adapter plates with a range of covers and control equipment Axter can satisfy all expectations of the architect or building owner in terms of aesthetics, comfort and safety.

Innovative products, unrivalled quality and commitment to service make Axter the first choice for rooflights and smoke control equipment.

Functionality

Rooflights have four essential functions :

  • Daylighting

  • Ventilation

  • Smoke/Evacuation
    Smoke evacuation
  • Roof access

DAYLIGHTING
Rooflights provide overhead natural daylight, saving energy on electric lighting and providing an evenly distributed light that enhances the internal environment. The health benefits of natural daylighting are well documented and Building Bulletin for Schools 90 "Lighting Design for Schools" recommends that natural lighting should always be the major source. Actual light levels depend upon the characteristics, dimensions and location of the installed units.
VENTILATION
Natural, controlled ventilation provides an effective alternative to air conditioning systems in modern buildings creating healthy living conditions, a precondition for physical and mental well being. Installing ventilation units reduces energy consumption, lowers operating expenses and allows savings of investment cost of air conditioning plant. Permanent trickle ventilation, available on all Axter units, reduces condensation.
SMOKE EVACUATION
In case of fire, natural smoke evacuation improves visibility to the emergency exits by partially evacuating smoke and combustion gases. This facilitates the evacuation of people and enables the early intervention of firemen. Gas and smoke evacuation reduces the risk of fire propagation within the building.
ROOF ACCESS
Safe and easy access to roofs can be provided without the need for external ladders or towers thus conforming to CDM requirements. Ladder attachments and grab handles enhance the safety aspects and inopportune intrusion can be prevented with grills and lockable gratings.

Control

All types of units have control requirements in common:

  • Controls
    Controls
Control mechanisms are required to open and close smoke evacuation and ventilation units. These fulfil regulations concerning smoke evacuation of public access buildings, protected stairwells, residential buildings etc. In addition to temperature sensitive fail-safe mechanisms, control can be mechanical, electromagnetic or pneumatic (CO2) linked to smoke detectors and to centralised control boxes as required.
