Instead of a "first point of water penetration" value, efficiency of the louver is measured instead. Basically, "how good is the louver at stopping the water?" The efficiency is rated as a percentage, determined from the amount of water that passes through the louver divided by the total water applied during the test. A very efficient louver will have a value from 99-100%. Inefficient louvers will have values below 85%, meaning they allow over 15% of the water applied to pass through the louver.
