fire stopping between joists

Hello,

Thank you for using the Ask Hilti Tool. This is a condition that we do come across occasionally and have provided engineering judgement details for in the past.

Hilti does not have a UL Listed System that matches your condition, however we can address your application through an engineering judgment which will be a detail showing your exact application with the firestop components to maintain the stated ratings. Please see the attached Hilti engineering judgment request form. Please fill out the form and email the completed form with any additional details to usfirestopeng@hilti.com If you have any questions, comments, or concerns please feel free to call or email us.

Thank you for choosing Hilti as your firestop specialist and have a great day.


Regards,

Nate Crawford
Fire Protection Engineer
