Yesterday we removed 3 old aluminium sliding windows which had 3mm float glass, and replaced them with new slightly larger residential framing( depth 60mm) glazed with 6.38 clear laminate glass. Awnings with chain winders and screens.  The result was quite dramatic, with a fair few compliments as people passed by.

3 of us on the first day, and1more morning to just finish some angles on the outside.
