My favorite brand of residential exterior doors is Thermatru for their durability, insulation, and weatherstripping. Andersen also has an extensive line of pretty good doors.

But I sure do like to see it when it’s possible to get fancy with crafted wood doors. Wood is not a bad insulation either, and stylish.

These folks make pretty good steel bulhead basement doors.
