I live in Minnesota. I have a full length glass storm door that faces
South. My interior door gets very hot even during October. I just put in
a new vinyl door and it has already warped a little. Since it is getting cold
I would prefer to keep the glass in the storm door.
Would adding a film on the storm door likely reduce the temperature
on my door to a reasonable level. If you have any other ideas please
let me know.

Thanks
