Product Description

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.

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
