Technical Statement
Product Description
The Ventüer VL-100CM is designed primarily as a screening louvre and provides a low pressure drop allowing maximum airflow with minimum mechanical assistance. It has very low rain defence effectiveness and should not be used where protection from wind driven rain is required.
The VL-100CM louvre blades are supported on a concealed mullion system, and bordered by a 150mm perimeter frame. It shares the same support frame as the high-performing VL-3SD and VL-2SD systems, and can be combined with these products to provide cost saving configurations. The standard frame can be fixed in to a wide range of primary support structures and cladding types, including profiled metal cladding, fibre cement sheet, window joinery systems and others.
It can be fitted with a sealed solid backing panel to provide a water-tight rainscreen in areas where the louvres are "inactive", or not required for air flow. It can also be fitted with bird or insect mesh.
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.
New Zealand Building Code (NZBC)
The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:

drawings the VL-100CM louvre system complies with the requirements around
external moisture as outline in New Zealand Building Code clause E2
Supporting evidence
The product has and can make available the following additional evidence to support the above statements:
Use in Service History
The
VL-100CM louvre system was developed in New Zealand in 2016. Since that time
it has been used extensively on a wide range of projects including storage
facilities, industrial buildings and education facilities throughout New
Zealand.

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
Refer to Ventüer Operation & Maintenance Manual
Warrantees

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.
