Exterior Aluminum Extrusion Wind Proof Louver Weather Vertical Louvers Architecture for Curtain Wall

  Product Description MULLION LINE LOUVREIntroductionThe Mullion Line series comes complete with visible support mullions. It has proven to be a real workhorse, withstanding rigorous testing to offer great rain defence performance and excellent airflow characteristics.Product DrawingLouvre ModelAL150RS-9AL75RSBlade ConfigurationDoubleSingleSystem Depth150 mm79 mmPitch75 mm62 mmVsiual Blade OreientationHorizontalHorizontalVisual Impact Of Mullions/JambsHiddenVisible                 Rainwater Penetration(Airflow Velocity In M/S)0.0AC0.5AC1.0BC1.5BD2.0CD2.5CD3.0DD3.5DDAirflow Coefficient0.2530.355Airflow Class32Aireflow RatingGoodVery GoodRecommend Products     TestingWeather Louvre: UK BSRIA/US AMCA TestingThe 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 AMCATwo key performance areas:1. Rain Defence ClassificationThe ability to prevent rainwater from penetrating the louverClass EffectivenessMax. allowed rain penetration l/h/m²11 to 0.990.7520.989 to 0.953.7530.949 to 0.8015.004Below 0.80Greater than 15.00NOTE: 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.
