Tested by BSRIA-EN-13030:2001
Design
Our 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 AMCA
Two key performance areas:
1. Rain Defence Classification
The ability to prevent rainwater from penetrating the louver

Two key performance areas:1. Rain Defence Classification
The ability to prevent rainwater from penetrating the louver
| Class | 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 |
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 Classification
A high coefficient means low resistance and high airflow performance
A high coefficient means low resistance and high airflow performance
| 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 |
