The louver appearance should play a significant role in louver selection. It is often ignored in favor of "function over form".

This will allow more blades in the frame and improve the appearance.

Special shapes:

Suggestion: Model E4JP

Use non-drainable louvers (models with J blades)- To view common special shapes . Use narrow blade spacings so the appearance will be more uniform (especially in short height louvers). Use high free area louvers - many of the special shapes have restricted free areas due to angles or rounding. A higher free area louver will help combat this loss of free space. E4JP, E6JP, E6JN
