Cresford has always been boasting: "CASA is walls of glass, stretched taut over a muscular 46 storey steel frame." So what the hell does that mean? They're boasting that they're using rebar?
What a bunch of lying weasels at Cresford! A significant selling point of this building has turned out to be bullshit!
There is no reason for them to use steel frame to construct this building - it's pretty rare that it's used at all in Toronto high-rise construction.
So they can legally say it will be a steel frame even though it will not?
The window frames may very well be made of steel. You are confusing an internal core structural system that doesn't make any sense in a condominium project vs the framing system that will hold the panes of glass in place for the windows.
I don't know why you'd want to live in a steel frame building over a concrete one. Concrete walls dampen noise a lot more than the alternative.
