Fieger have provided their FLW 28 units for Southern Health & Social Care Trust Centre, which provides a wide range of medical facilities.

Architects Kennedy FitzGerald specified natural ventilation using double-glazed louvres to complement the natural lighting effect, as well as a sustainable approach to maintaining a comfortable environment.

A specialist ventilation contractor, Crossflow Ltd, selected Fieger FLW 28 units to meet the requirements.

94 vents were installed complete with D+H LDF motors, programmed to prevent trapping.

The vents were manufactured with Saint-Gobain Cool-Lite SKN 165 solar protective glazing and a polyester powder finish to the framework.

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

Damien Day, Associate at Kennedy FitzGerald, said: “Fieger glazed louvres efficiently achieved natural ventilation levels via vertical panels whilst complying with window opening restriction requirements.”

“Window vent fenestration was restricted to this panel, maximising the amount of fenestration free glazed viewing panels. Building users who are standing or seated therefore have uninterrupted views of planting and land-scape in keeping with the architectural vision for the project.“
