We've had a new door fitted with sandblasted panes of glass (double glazed). We've noticed that instead of 2 sandblasted planes to make the double glazing, there is a clear pane on the outside (street side) and a sandblasted pane on the inside of our house. It looks a bit odd to me as from the outside clear pane looking in you can see various inperfections in the beading etc and I expected a sandblasted effect to both panes. Does anyone know if this is the usual approach? Many thanks!
