With single-glazed overlapping louvre blades and slim side glass fixings, the Ventüer HAHN-S9 louvre window has been developed for optimized, controlled ventilation. It combines good weather tightness with attractive architectural effect when insulated glazing is not necessary.
Single glazed louvre blades
Various glass thicknesses available, between 8 - 12mm, to suit project windloads
Glass blades will clear span up to 1600mm wide without intermediate mullions (wind zone dependent)
Certified to EN:12101-2 for use as a smoke ventilation device
Compatible with all common structure and cladding types, including precast concrete, metal cladding, fibre cement sheet, window joinery and unitised curtainwall systems
Extruded aluminium frame, available in standard RAL powdercoat colours or anodising
Multiple control options, including manual lever handle, electric actuators and pneumatic systems
Anti-finger entrapment sensors fitted to electric actuators as standard
Designed for use as a natural ventilation device or automated smoke ventilator
Single glazed blades available in thicknesses between 8 - 12mm which are able to span up to 1600mm wide without intermediate mullions (wind zone dependent)
Constructed with an extruded aluminium frame and suitable for salt-spray zones and other corrosive environments when powdercoated appropriately
Compatible with all common structure and cladding types, including precast concrete, metal cladding, fibre cement sheet and unitised curtainwall systems
Available with optional frame profile which integrates directly with standard window joinery, being set within the glazing pocket and being rubbered in
Multiple control options available, including manual lever handles, electric actuators and pneumatic systems
Certified for use as a smoke ventilation device as part of the building fire safety system
Limitations on Use
Due to being single glazed, the HAHN-S9 louvres do not provide a high level of thermal or acoustic insulation. If increased thermal or acoustic properties are required, consider using the HAHN-S9iV (double glazed) or HAHN-S9iVT (thermally broken) products instead.
Installation requirements for the HAHN-S9 glass louvre system vary dependent on the site wind loads, louvre panel sizes, cladding type and primary structure detailing. Ventüer provides full shop drawings for all installations which show sequencing, fixing type and sizing, flashing requirements and sealant details. Installers should make themselves fully conversant with these shop drawings prior to installation commencing.
Statement of Building Code Compliance
When sized correctly, the HAHN-S9 glass louvre system complies with the requirements for natural ventilation of buildings under the New Zealand Building Code clause G4
When installed in accordance with Ventüer technical literature, shop drawings and site-specific engineering the HAHN-S9 glass louvre system complies with the requirements for structure under the New Zealand Building Code clause B1
