Consider these other factors:

The louver appearance should play a significant role in louver selection. It is often ignored in favor of "function over form". However, with so many high performance louvers available the appearance can now be a major consideration. For example, if your louver heights are small, you will want a narrow blade spacing. This will allow more blades in the frame and improve the appearance. Below are our louver blade spacings listed by model:
