Andrew,
First of all, most U.S. builders who are trying to meet either the European Passivhaus standard or the PHIUS standard don't bother to buy a certified door. Passivhaus-certified doors have to be imported from Europe, and they are quite expensive. Most U.S. builders just choose a U.S.-made door -- they are still able to meet the Passivhaus standard or the PHIUS standard without a Passivhaus-certified door.

20-minute doors aren't that unusual -- they are the least stringent fire-rated door, and therefore less expensive than a 45-minute door, a 60-minute door, a 90-minute door, or a 180-minute door.

Martin,
Do you know of specific 20 minute door manufacturers / models that meet the standard that are from the U.S. ?
