Wood versus Steel
I love the look and security of some of the new steel doors which also use stained glass inserts. My contractor though says that steel warps as much as wood and is more difficult to install in old homes where the openings are not square. Which is better, wood or steel?
It sounds like you need a new carpenter. Does he mean that if he installs a wood door that he does not have to make the opening square? My own preference is wood for one reason. The steel will gravitate cold into the house much more than wood. Even though the doors are insulated and they have a thermal break, the cold air will still travel through to the inside of the house. Just my opinion.
