The Ventüer AL-450 louvre system is a 450mm deep, high performing acoustic louvre ideal for installations where high levels of noise reduction are required. Constructed with an extruded aluminium front blade profile, it offers a higher level of weather resistance than conventional acoustic louvres made from sheetmetal.
The rear of the louvre can be fitted with bird mesh, insect mesh or dust filters. Available in a wide range of standard powdercoat colours, the AL-450W is manufactured to order and can be fabricated in a wide range of sizes. Independently tested and certified to ISO 10140-2.
Should be used with caution in situations where water ingress is of concern as high wind speeds and heavy rainfall can result in water being blown between the blades.
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 a multi-stage ventilation louvre such as the Ventüer VL-3SD or VL-2SD louvre system instead. Note — these alternative louvres do not have acoustic properties.
Installation requirements for the AL-450W 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 AL-series of acoustic louvres were developed in New Zealand in 2019. Since that time they have been used on multiple projects throughout New Zealand, including apartments, hotels, industrial buildings and residential dwellings. Refer to the Ventüer website for detailed case studies.
Performance tested for acoustic properties to ISO 10140-2, the AL-450W has a STC rating of 18. Refer to Ventüer technical literature for detailed information regarding insertion loss and pressure drop.
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.
Ventüer designs and supplies engineered natural and mechanical ventilation products and systems for commercial, industrial and high-density residential construction projects.Product Enquiries
