This is not acceptable for a couple of reasons:
- The evaluation report from UL indicates it is only suitable for Type VB construction. Since this is a high rise Type IIA construction means they’re using it outside of the approved use.
- The penetrations require firestop assemblies tested per ASTM E 814 or UL 1479. This product has NOT been tested per either.
If there are drawings and specifications for the project that require tested firestop assemblies, then no credit is due—they should’ve been familiar with the contract requirements.Give the guy a little credit for trying. It says its good for residential construction, and he used it in a residence. At least it wasnt plain foam.

If I was the architect providing contract administration, I would reject the installation, even if the building accepted it. It is still a breach of contract. The contractor would be required to replace all of the non compliant materials and replace them with compliant materials. If the contractor refuses, the owner has the right to withhold payment on that portion of the work, and if the contractor still refuses to correct the deficiency, the owner can bring in a separate contractor to correct the work and charge the original contractor for the cost.Yes and when I ask for specs on the drawings I get resistance but this is what happens even when there are specs.
