Why Choose Aluminium Louvres?

Every project is different, regulations are constantly evolving and clients are becoming more demanding. As a proactive partner, CS Fabrication.


Ventilation louvres are an indispensable part of every building. They bring fresh outdoor air into the building, and they allow polluted indoor air to escape. In doing so, they help reduce the volume of harmful substances and humid air in your building.

The term 'ventilation louvre' is also occasionally used for window vents installed in or on a window. A window ventilation system uses these air supply vents as part of a centralised ventilation system.

How Does a Ventilation Louvre Work?

The main function of a ventilation louvre is to facilitate and/or control the proper flow of air. At the same time, ventilation louvres also offer protection against rain, wind, insects and much more. Ventilation louvres can also be used as aesthetic covers that still allow air to circulate.

As such, ventilation louvres have a dual function: they bring fresh air into the home, and they extract polluted air from the home.

Aluminium Louvres FAQs

1What should be considered when specifying aluminium louvres?
Key details include opening size, airflow requirements, free area, blade profile, frame depth, finish, colour, weather exposure and whether additional protection from insects, vermin or debris is required.
2Where are aluminium louvres commonly used?
Aluminium louvres are commonly used on commercial buildings, apartment schemes, plant rooms, schools, industrial units, data centres and service enclosures.
3Are aluminium louvres made to measure?
Yes. We manufacture aluminium louvres to suit the required opening size, frame depth, blade layout, finish and project specification.
4Can CS Fabrication manufacture louvres for plant rooms and service areas?
Yes. We can manufacture aluminium louvres for plant rooms, service areas and other spaces where airflow is needed. The louvre design can help ventilate the area while giving the exterior a cleaner appearance.
5Do aluminium louvres allow airflow while reducing weather exposure?
Yes. Aluminium louvres are designed to allow airflow while helping reduce direct rain and wind entry. The level of weather protection will depend on the blade profile, louvre depth, opening size and site exposure.
6What does free area mean when specifying louvres?
Free area refers to the open space within a louvre that allows air to pass through. A higher free area usually allows more airflow, but the final specification should also consider weather protection, screening and the needs of the ventilation system.
7Do aluminium louvres help protect against insects, vermin and debris?
Yes. Aluminium louvres can help protect ventilation openings from insects, vermin, rain, wind and debris while still allowing airflow through the building opening. The final level of protection will depend on the louvre design, opening size and project specification.
8What information is needed to price aluminium louvres?
To price aluminium louvres, we usually need the opening sizes, quantities, frame details, finish, colour, mesh requirements and any relevant drawings or specifications.
