Thanks for asking this question, as I've been wondering about this for months.
Quote:
The red paint is intumescent fire proofing, the unpainted steel well get spray on fire proofing ( basically a layer of cement sprayed onto the steel).
A BLANKET OF INSULATION
Intumescent coatings start turning to insulating foam at a temperature of 300°F - less than a hundred
degrees higher than boiling water. The heat sensitive ingredients in the smooth coating react and froth
up into a foam containing millions of tiny hollow cells. The expansion incredibly rapid. What was once
a smooth, decorative surface turns into a thick protective layer of insulation.

And thanks
Zensteeldude for your clear and thorough explanation.
So MY question is - if the fireproofing on the base is meant to be
"a smooth decorative surface" , it will be visible behind the glass panels that will be attached to the facade. Is this correct?
If this is so, I have never seen it (the red steel) in any renders to date (except the drawing posted recently).
Thanks in advance.
