DAP foam is a good non expanding foam for windows.
I hate to correct people that seem to know what they are talking about, but silicone is not a good choice with anything vinyl. Silicone does not stick to vinyl. Siliconized latex is better than silicone for sealing to the old stops. DAP has products rated at 35-50 yrs., OSI is another good brand.
