LOUVERS

Capturing water within the louver blade is not enough. Vertical drain channels within the louver mullion are essential to ensure that rainwater is not reintroduced to airflow but drained effectively away from the louver panels.   1.     VISIBLE MULLION   CLASSIFICATION B – C   Louver type:    Louver Pitch:    Louver Depth    Max Airlow Coefficient:    Max Pressure Drop:    Rain defense   RS 3200 (Single blade) 70 mm 78 mm 0.333 35 Pa 80% – 94.9% to 95% - 98.9%   CLASSIFICATION A – A Louver type:     Louver Pitch:     Louver Depth     Max Airlow Coefficient:     Max Pressure Drop:     Rain defense RS 5300 (DOUBLE BLADE) 70 mm 131 mm 0.233 70 Pa 99% – 100%     2.HIDDEN MULLION  CLASSIFICATION B – C Louver type:    Louver Pitch:    Louver Depth    Max Airlow Coefficient:    Max Pressure Drop:    Rain defense   RS 3105 (Single blade) 75 mm 76 mm 0.434 20 Pa 80% – 94.9% to 95% - 98.9%   CLASSIFICATION A – A Louver type:    Louver Pitch:    Louver Depth    Max Airlow Coefficient:    Max Pressure Drop:    Rain defense RS 7305 A+ (Double blade) 75 mm 152 mm 0.320 40 Pa 99% – 100% The Wind Driven Rain Test Facility allow C/S to analyze the performance of all of our louvers. Through experimentation with bending wind, C/S engineers have designed a louver system that allows air in building while keeping water out.
