Thank you. I see that you have a very low value for transparency (0.145), maybe that is why the glass is so clear. I will experiment with these values for glass in cupboard doors. I was never happy with how glass looked, close, but not 'the real thing'. I hope this will look better.

By-the-way, why use a wall for the glass and not a box? A box is much more efficient in both object size and rendering time. A wall uses almost twice as much vertices and faces as a box. Not much difference with just one wall but with many walls you will notice the difference.
