The CS 40 window is fully open which gives a good sound proof result. There is an opening clear in the small windows. There is no filtration through which dust and water can come out. It has a clear and straight look fromout side and has no chance of step appearance. It also has an amazing look of Arctic vision which makes it more appealing.
