Insulation works great to help stop drafts from a seldom-used exterior door in my office. Put this between the doors and problem solved.

...If you can find a good sheet
This is a fine product if you can find a good sheet, meaning one free of gouges, cuts, abrasions and missing corners. But this is typical of the Lowe's I frequent in Madison, GA. At this store, there is very little regard for the condition of the store/inventory. It seems that the only requirement of employment at this store is a pulse and the ability to put on a vest right side out.

Great product!
I loves this product. I just wish that they would take better care of the foam boards because a lot of them where damaged.
