We had a stunning crittall glass wall between our hallway and kitchen/dining room put in to our house a few months ago by Govette Windows.
They were absolutely great - installation team was very courteous, polite, and tidy. Some of the glass panes were dirty/scratched when they arrived, and they reordered, revisited, and replaced at no extra cost, and without any hassle.
The lead time was super long - more than 12 weeks I believe - so its great you 're thinking about it now.
Note that due to building regulations, you might need fire-rated crittall, since it involves the kitchen. In which case the cost goes up considerably - and the number of suppliers who can do it fall.
