[Bldg-sim] radiation through glazing

[Chris Yates]

An ex boss lived in a Passivhaus and he couldn't get signal in the middle
of London.

A triple glazed unit can be quite thick. There were also multiple layers of
foil faced insulation in the walls. The Passivhaus institut may have done
some research on this.
