We have TJI joist sitting on a bearing demising wall (no rim joist). This is an (5) story R-2 occupancy. Drywall will be put on the bottom of the TJI Joists. The contractor added blocking between each TJI Joist, but there are gaps at the web. Is there a product we can use to fill that gap to maintain our rating between Residential Units.
Hello Adam! Thank you for checking out ASK Hilti!
Unfortunately, we do not have a product or solution for your exact condition. This appears to be a draftstopping or fire blocking condition, in which we cannot assist with since this would technically not fall under the scope of firestopping in the eyes of the applicable code requirements.
It may be appropriate to work with the project's design team, building official (Authority Having Jurisdiction), or a fire protection firm to assess the situation and provide an appropriate solution.
