I have vinyl windows with wood frames like this-



Does the wood frame on the interior get nailed at all? I didn't think so but I noticed they are pretty flexible and I am concerned that even low expansion foam insulation might bow them if I don't.  ???

dug,
I would tear off glass from batts and stuff it, that way you can control the bow.
I do know the interior does not get nailed.
