Product Description

 

Product Description

VERTICAL LINE LOUVRE

Introduction

Performance louvers are architectural elements that are designed to enhance the performance of a building's ventilation system. They are typically made from high-quality materials such as aluminum, steel, or other metals, and are designed to provide maximum airflow and weather protection while minimizing noise and reducing energy costs.

 

Acoustic Louvers: Acoustic louvers are designed to reduce noise pollution by minimizing the amount of sound that passes through them. They are typically used in industrial or commercial applications where noise is a concern, such as power plants, manufacturing facilities, or transportation hubs.
Storm Louvers: Storm louvers are designed to provide protection against wind and rain, and are typically used in areas that are prone to extreme weather conditions. They are often installed in building facades or ventilation systems to protect against water damage.

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
