Engineered wood over steel floor

[alba2]

This is a new build flat and the stairs up to the flat and vestibule floor of the flat are 100% steel for fire escape purposes.

I want to lay engineered wood over the steel floor in the vestibule. The vestibule is on the top floor. As this is a floating floor should it simply be laid conventionally with 3mm acoustic underlay?

Have changed my mind about the 3mm underlay. I have decided to use 6mm Diall fibreboard.

Anyone laid over a steel floor before?

Still no comments re steel floor. No experience?

Perhaps no one here has done it, the only potential issues (assuming the floor is flat) are noise and condensation.

Thanks for replying.

I was hoping the 6mm fibreboard would be a solution for noise. The metal floor is on the top floor above the inernal communal stairs, so I am assuming condensation should not be a problem, or am I wrong?

Can't think there would be any issues in that case.
