The Ventüer VL-100S aluminium louvre system is a single bank double weather stop ventilation louvre. It has good rain defence and medium pressure drop, making it an excellent choice where the same louvre type need to be used in both exhaust and intake situations.
It comes with a flanged perimeter frame, and can be fitted with bird mesh, insect mesh or dust filters.
Available in a wide range of standard powdercoat colours, the VL-100S is manufactured to order and can be fabricated in a wide range of sizes. Independently tested and certified to BS/EN:13030.
Water ingress from wind driven rain can be substantial if exposed to high winds or situated where cross flow can occur (i.e. having louvres on both sides of an empty building such as a storage facility). If interior linings or equipment within the building can be damaged by exposure to water, consider using the double bank VL-2SD louvre system instead.
As this louvre is not self-draining, panels greater than 1500mm high will have reduced weather resistance due to water shedding from the upper blades and flooding the lower portion of the panel.
Installation requirements for the VL-100S 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-100S louvre system was developed in New Zealand in 2008. Since that time it has been used extensively on a wide range of projects including multi-story carparks, industrial buildings, aged care homes and storage facilities throughout New Zealand. Refer to the Ventüer website for detailed case studies
Performance tested for weather resistance and airflow performance to BS/EN:13030, the VL-100S is classified as follows:
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 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.
Ventuer designs and supplies engineered natural and mechanical ventilation products and systems for commercial, industrial and high-density residential construction projects.Product Enquiries
