I couldn’t read the print stenciled on the window of this door and didn’t see any other markings. Any chance this door is fire rated? Age of home is 1994.
1/4" wire glass and ceramic glass are the most
common types of glazing used in fire rated
doors. The hourly rating of the door dictates
the number and maximum size of the vision
lights used in the door.
If I find that door assembly on a residential garage house passage way here in California, it’s going in the report as an unsafe condition.
Look at the trim holding the glass in its plastic or vinyl, this door is not fire rated.
