VL-55S Slimline Ventilation Louvre
Description

The Ventüer VL-55S aluminium louvre system is a slim single bank ventilation louvre ideal for small grilles, exhaust vents, louvred doors and mechanical screening.

It comes with flanged and channel frame options, and can be fitted with bird mesh, insect mesh or dust filters.

Available in a wide range of standard powdercoat colours, the VL-55S is manufactured to order and can be fabricated in a wide range of sizes. Independently tested and certified to BS/EN:13030.

Key Features
  • Extruded aluminium construction, available in any standard powdercoat colour or anodising
  • Slim blade profile enables the construction of small louvre grilles and door inserts
  • High resistance to vandalism and damage thanks to sturdy construction
  • Can be fitted with ancillaries such as bird mesh, insect mesh, dust filters, mechanical dampers and plenums
  • Independently tested and certified to BS/EN:13031
Scope of Use
  • Slimline single bank louvre designed for small grilles and louvred doors where exposure to moderate levels of wind and rain are expected, and where some water carry over is acceptable
  • Slim blade profile enables the construction of small louvre grilles and door inserts
  • High resistance to vandalism and damage thanks to sturdy construction
  • Constructed from extruded aluminium 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
  • Ancillaries such as bird mesh, insect mesh, dust filters, mechanical dampers and plenums can be supplied fitted to the rear face

 

Limitations on Use

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.

Installation Requirements

Installation requirements for the VL-55S 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 VL-55S 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 VL-55S louvre system complies with the requirements for structure under the New Zealand Building Code clause B1
  • When installed in accordance with Ventüer technical literature and shop drawings the VL-55S louvre system complies with the requirements around external moisture as outline in New Zealand Building Code clause E2
In-Service History

The VL-55S louvre system was developed in New Zealand in 2008. Since that time it has been used extensively on a wide range of projects including apartments, schools, retail developments and industrial buildings throughout New Zealand. Refer to the Ventüer website for detailed case studies.

Other Performance Attributes

Performance tested for weather resistance and airflow performance to BS/EN:13030, the VL-55S is classified as follows:

  • Aerodynamic Coefficients:
    • Air Inlet: 0.226, Class 3
    • Air Extract: 0.231, Class 3
  • Rainwater Penetration:
    • Class C — up to 1.0m/s suction velocity
    • Class D — up to 3.5m/s suction velocity

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 and Maintenance

Warranty information and maintenance requirements to comply with B2 can be found in the Ventüer Aluminium Ventilation Louvre Operation & Maintenance Manual.

Environmental Information

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.
