I have a deep window frame above my front door. It currently has a
single glazed pane in it. I was wondering whether anyone has had any
experience getting a correct sized double glazed pane made up and
fitting it into the existing frame.

Are glazing companies willing to make a double glazed pane for this?
And would it be cheap enough to be worthwhile. Also, would the double
glazed pane fit OK into the existing pane? It is deep enough to
accomodate the pane from what I can tell.

Thanks in advance

Jim
