Exterior door in Interior Jamb??

jrmac99

Wanting to hang an exterior grade door in an existing opening that currently has a typical hollow-core door leading into our cold room in basement.

Question is do I have to strip all the way back to the jamb or can I hang the exterior door in existing jamb space??

The only difference between interior and exterior jams is the exterior has built in weather stripping and a weather tight threshold. Both can be removed. Or to the interior both can be added. But the hinge location and size is also different.

If it's a typical pre-hung interior door with a "split" jamb, I wouldn't hang an exterior door on it. The exterior jamb is stronger and will support the heavier door better. Besides the difference in hinge size, some older interior pre-hung doors only came with two hinges and an exterior would require three. (The ones I tore out of my house had only two.) A pre-hung exterior door would be easy to install, and as Bob mentioned comes with all the appropriate weatherstripping and a threshold to seal it tightly.....

Exterior doors are normally 1 3/4", while interior doors are 1 3/8" thick. The stops would have to be moved.
