Fieger have provided their FLW 28 units for The Hawkhead Centre, a new activity and support centre for the charity Scottish War Blinded, which provides free support to ex-service men and women who have lost their sight during or after military service.

The design team at Page Park Architects specified natural ventilation using double-glazed louvres to complement the natural lighting effect, as well as a sustainable approach to maintaining a comfortable environment.

Gray & Dick Ltd selected Fieger FLW 28 units to meet the requirements for extract via the Rooflights and inlet air through the West elevation.

The vents were manufactured using Saint-Gobain Cool-Lite SKN 176 & 174 solar protective glazing with a Ritec coating and a RAL 7012 Basalt Grey polyester powder finish to the frame-work.

The low-level vents were fitted with D+H LDF motors, programmed to prevent trapping.

In addition to normal day-to-day use, the vents are the “SmoTec” type, tested to EN 12101-2 for use in emergency smoke venting.

A key characteristic of the vents is the energy efficient design, achieved by the class-leading low air leakage rate, together with low U-values.

To assist with enabling a flow of fresh air through the building, as well as in fire conditions, Fieger FLM single-glazed louvre vents were installed above an internal partition wall.

The design of the roof meant that the vents had to be manufactured with a sloping top frame.
