Product Description

Scope of use

Designed for use as a screening louvre, as a decorative facade element or as a visual screen around mechanical plant enclosures. Constructed from extruded aluminium and suitable for salt-spray zones and other corrosive environments when powdercoated appropriately. Typically fixed directly to primary building structure such as walls or columns. Not suitable for use as a weather louvre due to its low resistance to wind driven rain.

Product Criteria

Design requirements

- Extruded aluminium construction, available in any standard powdercoat colour or anodising

- No size limitations (the clip-fixed front blade profile provides a continuous appearance)

- Excellent airflow characteristics, allowing maximum ventilation to mechanical equipment

- Independently tested and certified to BS/EN:13031

- Cost effective  

- The VL-100CM should not be used as a weather louvre due to its low resistance to wind driven rain.

Installation requirements

Installation requirements for the VL-100CM 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.

Maintenance requirements

Company Product Information

Environmental

All Ventüer ventilation louvre systems are fabricated from aluminium which is extruded locally here in New Zealand. The majority of this aluminium is "green aluminium", meaning that the electricity for smelting is supplied from renewable energy sources (such as is the case with Tiwai Point, which relies on hydro-power). Any waste generated during manufacture is fully recycled, as can be any louvres at the end of their useful life. All powdercoating of louvre components is carried out by certified applicators and the use of chomate treatment processes is strictly avoided.

Effective use of passive ventilation devices such as louvre systems can significantly reduce the energy consumption of a building, reducing both its carbon footprint and whole of life cost.
