Façade Single Leaf – Residential (FSL-R)

Product features and details.
Product Overview

Façade Single Leaf – Residential (FSL-R) smoke vent windows are mounted in façades to provide smoke and heat ventilation, air inlet, comfort ventilation and daylight. They are particularly suited to apartments and commercial buildings at the head of stairs or end of corridors.

With their thermally broken aluminium profiles and a wide range of double and triple glazed options they are able to meet the strictest thermal requirements. The frame may be polyester powder coated to any RAL colour and incorporated assembly grooves to enable hidden cable management.

They are configured as bottom hung opening out units and incorporate chain or spindle actuators enabling a wide range of size options or opening angles and ventilation areas.

Specific Features
  • Fully certified to BS EN 12101-2 for smoke and heat ventilation
  • May be used for comfort ventilation
  • Thermally broken aluminium profiles give excellent thermal properties
  • Available with double and triple glazing for increased thermal performance or solid aluminium panel where no daylight is required
  • May be installed in structural openings or as part of a patent glazed system
  • Wide range of sizes and opening angles utilizing chain or spindle actuators
Optional Features
  • Vertical frame connection detail for continuous vertical louvres for high atriums or feature glazing
  • Security bars may be installed to reduce the opening width to 100m to achieve guidance of Approved Document K
  • A wide range of glass to achieve specific Light Transmission (LT) and Solar Gain (g-value)
  • A range of aluminium cills are available to enable units to be installed in masonry facade and maintain weathering detail
