All Ventüer products are independently performance tested and certified. Some of the international standards that apply to our systems include;
BS/EN:13030 – Classification Of Natural Ventilators
BS/EN:12101-3 – Smoke and Heat Control Systems
AS:1191-2002 – Acoustic Testing For Airborne Sound In Building Elements
DIN: 18032-3 – Safety Against Ball Throwing
Below is a video showing one of the Ventüer ventilation louvres undergoing BS/EN:13030 testing at BSRIA in Bracknell, UK. This test is carried out by having water blown at the face of the louvre panel, simulating 75mm/hour rainfall with 13m/second wind. The chamber behind the louvre panel is fitted with a fan, drawing air inwards to simulate the action of an air intake of a mechanical ventilation plant. The intake flow is varied, from 0.0m3/s to 3.5m3/s, and readings are taken to establish what level of water ingress occurs at each intake rate.
Ventüer has tested its ventilation louvre systems to BS/EN:13030 for several years now. While other manufacturers sometimes use the American standard AMCA 500-L to test their louvres, we believe that the British standard is a much more accurate representation of field performance and results in more data for the mechanical consultants to base their decisions on.
