2024 IWUIC Class 1 and 2 20-minute exterior-door path
The unamended 2024 IWUIC model code includes a 20-minute fire-protection-rated exterior door path in Class 1 and Class 2 construction.
A documented rating can match this path, but the code excerpt does not name the product's test method. Listing scope, frame, glazing, hardware, installation, and local amendments remain checks.
Published requirement text
“have a fire protection rating of not less than 20 minutes”
