UL 1784 covers the testing of air leakage through door assemblies and other opening protectives installed in wall openings where air leakage is intended to be controlled.

One of the most powerful questions we can ask is: Does Your Door System Meet the Standard? Knowing the code in your territory, and understanding it well enough to ask local code officials if they are (or are not) enforcing it, or to educate architects and other customers what needs to be done to meet the standard can be a great way to get in front of key audiences.

Total Door Systems is the only integrated assembly that exceeds the testing and rating requirements for elevator, hoistway, and elevator lobby codes. We will be making informative cut sheets like this UL 1784 available on a consistent basis for your use.

We see plenty of confusion in the field about how standards and codes apply. Take a look at the door in this example, and you’ll see just what we mean. This application requires a fire rated glass. This picture shows a door with tempered glass and no latching device. This does not meet the intent of the code. Get acquainted with code UL 1784. Total Door Systems is the only integrated assembly that exceeds the testing and rating requirements for elevator, hoistway, and elevator lobby doors.

Part of the benefit of a Total Door System is that we take the guesswork out of how multiple codes and standards apply to your installation by ensuring they exceed existing life safety standards. We’re the experts, so that you don’t have to be.
