Its probably not considered neccessary. Fridge doors need a seal to keep in the cold air and maintain freshness. They would need to create doors with the seal...and a door frame with the right surfaces...it would get costly.

Here is a link that might be useful: Cladding

Many (all?) fridge seals are magnetic, so you'd be limited to steel doors.

"...you'd be limited to steel doors."

Or a steel door jamb (or steel covering) with the seal mounted on the door.

It would be significant overkill and very costly.

There are already many effective ways of creating a seal in exterior doors (and some that are actually similar to the seal used on refrigerators - compressible flexible gasketing).

I though it would be significant overkill and very costly, but then I realized the fridge companies manage to do it low-cost....

I don't know if it would be better than the current alternatives, when the wind is blowing or there is a pressure difference between indoors and outdoors. I've seen "compressible flexible gasketing" doesn't stop cold air from coming in.

"I realized the fridge companies manage to do it low-cost...."

With what lifetime?

Do you want to have to replace the seal on your door after 10 years?
15 years?

Things like appliances have a far shorter life span than houses.

Sounded like a good idea to me. We have handmade doors from 25 years ago, and many have a noticeable breeze especially in winter. They are just not square and weather stripping doesn't solve it. It would be better if doors fit against the frame instead of into the opening, more like a fridge, with an ability to lock.

I've got magnetic weatherstripping on my steel front door.
