Best in its class, the Ventüer VL-2SD is a high performing two-stage weather louvre that provides optimum rain defence. The extruded aluminium louvre blades are supported on a two-piece pressure equalised mullion system, and bordered by a 150mm frame that ejects captured water to the front of the panel.
Like the VL-3SD triple bank system, it can be combined with the VL-50CM louvre system to provide cost savings in inactive (blanked off) areas, and can also be fitted with bird mesh, insect mesh or dust filters.
Available in a wide range of standard powdercoat colours, the VL-2SD is manufactured to order and can be fabricated in a wide range of sizes. Independently tested and certified to BS/EN:13030.
Due to its relatively high pressure loss, the VL-2SD should be used with care when mechanical plant is operating near the limit of its design capacity. If a lower pressure loss is required and a moderate level of water ingress is acceptable, consider using the VL-104D louvre system instead.
Installation requirements for the VL-2SD 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.
The VL-2SD louvre system was developed in New Zealand in 2013. Since that time it has been used extensively on a wide range of projects including hospitals, apartments, commercial office towers and events centres throughout New Zealand. Refer to the Ventüer website for detailed case studies.
Engineered to withstand site-specific structural, seismic and wind loads in accordance with NZS:1170
Fixings, flashings and sealant details are designed to comply with NZ Building Code Clause E2
Warranty information and maintenance requirements to comply with B2 can be found in the Ventüer Aluminium Ventilation Louvre Operation & Maintenance Manual.
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 chromate 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.
Ventüer designs and supplies engineered natural and mechanical ventilation products and systems for commercial, industrial and high-density residential construction projects.Product Enquiries
