Engineering Judgement (EJ) requests

Hilti's custom drawings.

Our Hilti firestop solutions are tested against the most stringent test standards such as ASTM/UL and EN1366-3 and -4.

But it’s not possible to test every firestop application, because construction projects are all very different.

That’s why we offer Engineering Judgements. These are custom drawings, which we create for you.

Engineering Judgements are designed for applications, which aren’t approved by international or national guidelines.

We can provide engineering judgements for:

  • Construction joints
  • Curtain wall joints
  • MEP Through Penetrations

We’re happy to help onsite, online or on the phone.

For more information on Hilti engineering judgements or to start the process; fill out a "Contact Me" form.
