I am completely obsessed with this blog.
beautiful!
We used Crittal windows & doors for this house.

It's also our civic duty to remind people that large expanses of glass might require upping the thermostat considerably. I'm working on a project now and we'd like to use reclaimed storefront windows but the energy modelling shows the building would perform horribly.
Double or triple panes with steel framing, combined with lots of wall and ceiling insulation and a groundsource geothermal HVAC create an aesthetically beautiful and ecologically mindful application.
Are these insulated? If not, and they're just a single piece of metal that spans from the outdoors to the indoors, they will conduct cold inwards and it could be extremely uncomfortable. I imagine that they must be insulated - though they don't look as if they are. I live in an old church with metal windows, and though they're double-glazed, you just have to walk by them to feel the cold wind emanating off them. At first I thought my windows were unsealed, or actually wide open, until I realized the cold was actually coming in via conduction. Some modern metal windows have a layer of plastic or foam sandwiched inside so that there is no uninterrupted metal that goes all the way from outside to inside, and one day I'm going to replace all my windows with those. I have an uninsulated, double-glazed metal window above my desk and in winter my hands become so cold from the downdraft that I can barely type.
PS! These windows are all gorgeous.
The kind of steel window is preferably chosen by the people right about this time, modern times. They are using this type of window because it makes their houses more elegant looking. It can give a relaxing ambiance. You may be able to see everything in every way because it was easily cleaned up.
