If that's the Hancock Tower in Boston, the reason the windows were popping out was the dual-pane glass was too rigid to withstand the thermal cycling during the day. The building was also plagued with other problems, like not being stiff enough to resist wind-loading and swaying dangerously. That problem was solved using two 300 ton weights, which were installed to damp the movement of the building. Additional reinforcement was also added to the building to help resist the torsional forces caused by wind loading that might have otherwise caused the building to fall over.
I don't think Dow Corning 795 was used in the building, since I don't think the product was available when the Hancock was built. It is probably since superseded whatever structural adhesive was previously used.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
