Opinion: Fasteners for fire-resistive construction

Inquiry: 98-43

Subject: Fasteners for fire-resistive construction

Code:
1994 UBC Table 7-B

Submitted By: MN B. O. Uniformity Committee

Approved By: Thomas R. Joachim, State Building Official

Issue Date: August 3, 1998

Question: Are pneumatic roofing nails approved for nailing a single ply of gypsum sheathing on a fire-resistive wall?

Answer: No. However, if other types of fasteners are proposed having an evaluation report that permits their use in a specific assembly, then they could be accepted as an alternate approved material.

Committee comments:

Footnote 1 of Table 7-B permits staples as fasteners only for those designs in Table 7-B. This footnote does not apply to the designs found in the Gypsum Association's Fire-Resistance Design Manual.

Adopted by committee November 20, 1997 and ratified at the 42nd Annual Institute of Building Officials on January 16, 1998.
