Aluminum Exterior Louvre Weather Storm Proof Louver Horizontal Single Double Bank Vertical Louvers

  Product DescriptionVERTICAL LINE LOUVREIntroductionDesigned 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.Product Drawing  Louvre ModelVDL 150-3VSBL 95-3Blade ConfigurationDoubleSingleSystem Depth150 mm95 mmPitch75 mm65 mmVsiual Blade OreientationVerticalVerticalVisual Impact Of Mullions/JambsHiddenVisible                 Rainwater Penetration(Airflow Velocity In M/S)0.0AB0.5AB1.0AB1.5AB2.0AB2.5AC3.0AC3.5ACAirflow Coefficient0.2750.267Airflow Class33Aireflow RatingGoodGood  Recommend 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.
