Exterior Aluminum Louver Vertical Aluminum Weather Louver Vertical Airfoil for Curtain Wall
Overview Product Description Vertical Double Bank Louver VDL150-3 Rainwater Penetration Coefficient of Entry Tested by B
Overview
Rainwater Penetration
Coefficient of Entry
Tested by BSRIA-EN-13030:2001Design
NOTE: Water Penetration Effectiveness is measured for each of eight face velocities between 0m/s and 3.5m/s under fan-driven wind at a speed of 13m/s and water sprayed as rainfall at a rate of 75 l/h conditions.2. Discharge Loss Coefficient ClassificationA high coefficient means low resistance and high airflow performance

Tested by BSRIA-EN-13030:2001Design
DesignOur performance louver systems are designed using airflow simulation by CFD(computational fluid dynamics)software to get the best balance between airflow and rain defense performance
Testing
Weather Louvre: UK BSRIA/US AMCA Testing
The industry standard for weather testing of Louver in the UK was developed by BSRIA(Building Services Research & Information Association) and HEVAC adopted in 2001 as a British & European Standard: BS EN 13030:2001. The principles of EN 13030 are replicated in the USA under the AMCA Standard 500-L, "Laboratory Methods of Testing Louvers for Rating"All of our louver systems have been tested either by BSRIA or by AMCATwo key performance areas:1. Rain Defence ClassificationThe ability to prevent rainwater from penetrating the louverClass | Effectiveness | Max. allowed rain penetration l/h/m² |
1 | 1 to 0.99 | 0.75 |
2 | 0.989 to 0.95 | 3.75 |
3 | 0.949 to 0.80 | 15.00 |
4 | Below 0.80 | Greater than 15.00 |
Class | Airflow Effectiveness | Performance Rating |
1 | 0.4 to 1 | Excellent |
2 | 0.3 to 0.399 | Very Good |
3 | 0.2 to 0.299 | Good |
4 | 0.199 & below | Fair |
