insulating between bay window panes trim

[tomaz64]

Hi,
Have discovered that outside trim on 5 windowed bay dg window has no insulation between each connecting pane if that makes sense,just a large plastic trim covering each interconnecting pane kept on with double sided glazing tape and a gap at the top approx 2 inch hole that the trim was hiding .Was considering filling these gaps with expanding foam but wondering about what to use between each connecting pane before reapplying the plastic trim.Windows must be approx 13 yrs old
Many thanks

Can you upload some pics?

As a general rule expanding foam is perfect for these types of jobs
