How to Choose a Fire-Rated Access Door: Rating, Label, and Wall Type

A fire-rated access door has to match the fire-resistance rating of the wall or ceiling it sits in, carry the right listing label, and mount the way the assembly requires. Four things decide the model.

1. Fire-resistance rating

Match the door to the rated assembly. Wall access doors are most commonly 1.5 hour (a B label), and ceiling access doors are commonly 3 hour, with 1 and 2 hour also available. Read the required rating off the drawing or the wall type, and do not under-rate the door.

2. The listing label

A fire-rated access door is listed and labeled by UL or by Warnock Hersey (Intertek). The label is what an inspector looks for, so confirm the product carries the listing for the rating you need.

3. Mounting and wall type

Access doors are made for surface mounting, recessed drywall or masonry mounting, and upward-opening ceiling installation. Choose the mounting for the wall type (drywall, masonry, or shaft wall) and the finish (primed steel, stainless, or a drywall bead frame for a flush look).

4. Insulated or non-insulated

Insulated doors are temperature-rise rated: they limit how much the unexposed face heats up, which some assemblies require to protect what is behind the wall. Non-insulated doors maintain the fire barrier without a temperature-rise limit. Confirm which the assembly calls for.
