Thanks AK wheeler! After thinking some more about these gates, the foam could help the gate from frosting up, especially in our climate. This doesn’t explain the foam on gates on the interior box though. If it was for sealing, then why didn’t the just put foam on the edges of the gate...
In the process of renewing my heater / blower and can’t figure out what the foam on the gates or doors are for. It doesn’t filter air. Is it for insulating the heater /blower doors? Why? I do understand the seals against fire wall and body fresh air inlet.
Secondly, what is the best...
