Door pan condensation – GreenBuildingAdvisor

I think removing the door pan could cause more issues if it is used to prevent cold air outside or water from the outside.

And what is causing the condensation is the cold aluminum exposed outside, making the whole pan cold, meets the hot air inside, then condensation happens. If the aluminum is insulated inside, it doesn’t meet the hot air, and no condensation happens.

Now how do you insulate it? Not sure. I’m thinking some kind of PVC trim and use caulk to cover it up and attach and try to make it look nice is my long-term solution. My short term solution which I learned from some co-workers at a door company, is use a pool noodle, tape it on to avoid exposure to hot air..
