I am looking for a fiberglass door for multi-family residential housing that is a panel design but with the bottom smooth area at least 10 inches to comply with accessibility requirements. The door needs to be STC 26 (I think...maybe 29) and 20 minute rated. Has anyone come across one that fits this description. |

Actually, I should be more specific. Here is a link to their rated fiberglass doors. I used these a LOT over the past 15 years on tens of thousands of doors at hundreds of projects.

I believe my client spoke with them and the bottom smooth portion (below the lowest panel) is not 10 inches and therefore doesn't comply with accessibility requirements |

I also don't think you'll get STC 29. A few years ago the few manufacturers who had done testing (on steel doors) got about STC 25 or 26. This may have changed recently, however, I suspect not because the construction of these types of doors is unlikely to have changed. Fiberglass faces did not perform notably differently than steel. If you really need the acoustic performance on a door that has a residential appearance, you have to use a secondary (storm) door. That shoots your STC up to around 40.
I don't know about the 10 inch lower rail requirement. Since the market for these is mostly single family, they are not particularly focused on this. As an alternative, you could use a wood stile and rail door manufactured by one of the many wood door manufacturers. They definitely have these. On the other hand, they all say their doors are not for exterior use(!) and won't provide a warranty. Odd, since many of us grew up in houses with wood doors that lasted fine. I think if you use a decay resistant wood, such as Douglas fir, the door will last fine if kept painted. |

I wonder why the bottom of a door has to be smooth up to 10" above the floor, when the required toe clearance is only 9" |

ADAAG 404.2.10 requires a 10 inch tall smooth surface on the push side of swing doors measured from the finished floor surface.
Watch out for jurisdictions that may still use an older ANSI A117.1 reference - at one time earlier versions required 12 inch bottom rails.
