My contractor is using EnerFoam by DOW to insulate the around the
frames
of my inserts. IS this the proper stuff to use. I alwasy heard that
the stuff to use should be non expandable, but the stuff he used is
definitely expandable stuff.

Is this the right stuff? He already has done 2 our of 15 windows and
the 2 windows that he used the EnerFoam stuff work well. One is a
vertical slider and one is a casement. My concern is that they will
bow
over time. If they didn't bow now can they still bow over time?

Should he be using non expandable foam? If so what is the best
product(s) he shoudl be using?

Expandable foam does expand, but it doesn't continue to expand over
time.
I'm quite sure it has already expanded to its full capacity. If the
windows are fine now, they should be fine in the future. If your
workman
knows what he's doing, then he applied the correct amount of foam with
the
anticipation of how much it would expand. Persnally, I prefer it over
the
non expanding foam, as it fills every crevice without fail.
