Vertical Line Louvre

Introduction
Designed for optimal performance in rain defense, vertical louvre systems are more effective than their horizontal counterparts as every louvre blade facilitates drainage of the louvre system through gravity. The result is improved rain defense capability, with no adverse effect on airflow performance.

The double bank louver VDL150-3 series has the highest rainwater penetration as Class A at 3.5m/s while the airflow class as 3. 
The single bank louver VSBL 95-3 series has very good air flowing rate and airflow class as 3. 
Both of them have BSRIC test report. And Togen can provide free area calculation basing on the segment sizes of louvre for each project.
