Design considerations include:Site location and exposureSeverity of local (site) weather conditionsLocation and exposure of louvres on buildingAirflow rate and direction through louvreMaximum acceptable pressure dropDegree and depth of water penetration acceptableSpecial solutions for sloping applications· Single bank,Double bank,Triple bank for optional.For a true comparison of performance, the aerodynamic coefficient and the degree of rain defence effectiveness are the only sensible measures ,Approved by BSRIA UK。
