I read that paper a while ago, i was actually looking for it recently but forgot its title.

Have you done triple glazing estimates with soundflow? It would be interesting to compare them to test data in the CBD and Vinokur papers.

If the computer models are limited, and math not that accurate, then how do we asses these situations?

Ive only ever used double glazed windows, and just used a mass based approach. The triple glazing scenario seems to require more than that.
