Screening Louvres
Designed for architectural screening and ventilation where high airflow is required and rain defence is not the primary consideration.

COLT louvre systems
Performance Louvre & Ventilation Solutions.
Colt has extensive international experience in high-performance louvre and ventilation systems for data centres and other demanding building applications.
From façade and rooftop ventilation to screening, rain defence and acoustic attenuation, Colt systems are developed to manage airflow, weather exposure and noise while integrating with the architectural envelope.
In Australia, Colt Universal Louvre systems have been applied at the Norwest Data Centre in Sydney, where 1UL, 2UL and 3UL configurations addressed different screening, ventilation and rain-defence requirements.

COLT Louvre Systems
Choose a louvre system by the performance your project requires.
Start with the façade requirement, then compare the COLT systems designed for it. Each category below brings together the relevant models without losing the technical distinction between them.
Weather Louvres
Designed to combine ventilation with enhanced protection against wind-driven rain, using blade profiles and depths matched to the project requirement.
Ventilation & rain
Rain defence + airflow
High-Performance Rain Defence
Multi-bank louvre systems engineered for applications requiring increased rain defence while maintaining effective airflow.

Operable Louvres
Operable systems provide controlled ventilation and closure, from pivoting louvre blades to fixed louvre-and-damper combinations.
Control & closure

Acoustic Louvres
Acoustic louvre systems combine ventilation with sound attenuation for plant rooms, mechanical services and other noise-sensitive applications.

Selected project experience
COLT in application.
COLT louvre systems have been applied across commercial, infrastructure and specialist building environments where ventilation, screening and weather protection form part of the façade strategy.
Norwest Data Centre, originally developed for IBM Australia, uses the COLT Universal Louvre family across 1UL, 2UL and 3UL configurations.
