The Quarter is a high quality apartment development by Urbeo in Citywest, a large satellite town approximately 15 km south-west of Dublin city centre. It is a well serviced urban area with good transport links and amenities as well as business parks such as Citywest Business Campus and Magna Business Park.

Working with Cairn Homes, Crossflow Air Conditioning Ltd were engaged to fulfil the smoke control requirements. They selected FIEGER Louvre Windows and a total of 136 no. FIEGER FLW 32 SmoTec vents were installed in the facades to the main stairs and corridors across the three phases of the development.

Each vent comprises double-glazed louvres, using toughened glass outside and laminated glass inside and provides a minimum geometric free area of 1.5 m2. All vents were supplied with stainless steel crossbars for added security and some with fixed louvre blades.

The vents were finished in polyester powder to RAL 7015 Slate Grey and were supplied with pre-drilled side fixing holes to facilitate installation on site.

The vents were each fitted with D+H LDF 100-70 24V DC motors, programmed for anti-trapping, which were wired to the control system installed by Crossflow Air Conditioning Ltd, using bespoke control panels, interfaced with the smoke detectors.

Typical overall U-values of 1.90 W/m2 K were achieved, which with a class-leading low air leakage rate to Class 4 of EN 12207 provides a highly energy efficient feature of the installation.

In addition to mandatory testing to EN 12101-2 for natural smoke vents, the FLW 32 SmoTec vent has also been tested to a range of European Standards.
