Useful Links to Articles on the Proper Method of Installations for Various Types of Doors:
1) Flashing a door rough opening is a very important step that is often skipped when installing a new door.
See video http://www.finehomebuilding.com/how-to/video/flash-rough-opening.aspx.
2) Installing French Doors – Journal of Light Construction (FEB 2010).
3) We highly recommend the new composite pre-hung doors with integral threshold similar to the Endura Framesaver. The bottom 8-12″ of these frames are made of composite wood guaranteed for life against termites and rot. Check out their videos. I also suggest using composite or PVC door brick moldings and a pre-made sloped sill pan.
