Serious remodel project. Didn't know picture windows available that big.
Its called curtain wall cladding where they use fixed point glazing if you look close you can see a structure behind some of the sections often times the architect will specify no frame work around the panels using only a clear adhesive in the panel joints from a distance it gives the illusion that the glass is 1 piece for the whole wall
That is one of those jobs that would be pretty cool to do. In schools, they never talk about about all of the really cool jobs that are available to people.
That's because the really cool jobs are blue collar, with involved skills and don't fill universities with wealthy students. While immense corporations spend real physical time and money on STEM education to support their future; it reflects poorly that trade unions participate so little.
...we'll learn more by wandering than searching...
