Design

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

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

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

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
