Spur® Triple Stage Louvres
Overview
Spur® Triple stage louvre systems are Arcadia's highest performing rain defence louvre providing guaranteed weather performance for highly sensitive buildings and plant rooms with sensitive equipment, while still requiring airflow. These louvre systems are internally drained providing engineers and architects guaranteed performance outcomes for high specification buildings. When designing these louvre systems, airflow and discharge coefficient have been considered ensuring reasonable levels of airflow can still be achieved through the Louvre system. Triple stage louvre systems also provided a guaranteed screening outcome with Zero visibility through the Louvre system.

Propelling High Performing Louvre Designs to Meet HVAC and Engineering Needs
Specifying weather louvres can be challenging, and if you don’t take into account all of the relevant considerations, you risk selecting the incorrect louvres for your project. Check out our whitepaper our educational whitepaper to help guide you draft an effective louvre specification.
Using a Testified and Certified Louvre System
The Australian Standard AS4740 sets out the requirements of testing of louvre systems. This testing is conducted in a testing rig and provides industries standards for airflow performance and rain defence. An untested and uncertified louvre system can result in poor airflow performance and impact on personnel wellbeing. The Spur® Fixed Louvre Systems have been exhaustively tested and certified using Australian Standards AS 4740.
Airflow Performance
Louvre airflow performance is affected by a range of physical elements including the louvre blade configuration, the louvre depth, the quantity of passes (single, double, triple stages), the louvre blade shape and any protrusions that interfere with the free flow of the air or that cause turbulence. Increased air velocity may cause varying areas of turbulence and flow disturbance which affect the louvre performance.
Providing Rain Defence
Rain defence performance of a louvre is tested with a 13m/s constant velocity of wind perpendicular to the louvre face and 75mm/h simulated rain droplets infused into the airflow for a period of 30 to 60 minutes. Intake velocities are altered throughout the test from 0.5m/s to 3.5m/s. Water ingress is measured at the internal of the louvres to provide a louvre rain defence result.
Factors to Consider
Severity of local (site) weather conditions, Location and exposure of louvres on building, Airflow rate and direction through louvre, Maximum allowable water penetration, Maximum acceptable pressure drop , Relevant performance data (site requirements), Special solutions for sloping applications and Building Aesthetics
