During the renovation of the heating plant of the Policlinico Hospital of Borgo Roma in Verona the installer used four twin wall Isotherm Ø1000 and Ø850 chimneys with a 50 mm high density mineral wool insulation.
All four chimneys were placed within a triangular framework that was placed on a reinforced concrete plinth built for this installation specifically.

The total height of each chimney is 20 m
