Consult fire resistive listings for fastener types and spacing.  Fastening patterns may vary depending on specific windload and fire resistive requirements.

FIRE RESISTANT DATA

  1. Wall Panels
    1. The finished panel in a four (4) inch thickness shall meet the requirements of a one (1)-hour fire resistance rating for a non-bearing wall in accordance with UL263 per (UL design U050 for US and design W021 for Canada), ASTM E 119 and CAN/ULC S101 (per Intertek design MS/WA 60-1).
    2. The finished panel in a six (6) inch thickness meets the requirements of a two (2)-hour fire resistance rating for a non-bearing wall in accordance with ASTM E 119 and CAN/ULC S101 (per Intertek design MS/WA 120-1).
    3. The finished panel in a seven (7) inch thickness shall meet the requirements of a two (2)-hour fire resistance rating for a non-bearing wall in accordance with UL 263 (per UL design U050 for US and design W021 for Canada).
    4. The finished panel in an eight (8) inch thickness shall meet the requirements of a three (3)-hour fire resistance rating for a non-bearing wall in accordance with UL 263 (per UL design U050 for US and W021 for Canada).
  2.  Ceiling Panels
    1. The finished panel in a six (6) inch thickness shall meet the requirements of a one and a half (1-½) hour fire resistance rating for a ceiling in accordance with ASTM E 119 and CAN/ULC S101 (per Intertek design FC200).
  3. Wall-framing support members and adjacent construction may require fire protection as specified by applicable building code. The customer is responsible for specifying the appropriate fire protection of these areas.Notice: The information herein is intended to provide a general understanding of the ThermalSafe® panel and related fire protection requirements. For any specific application, the exact fire protection requirements must be obtained from the appropriate state/local building code and/or fire code authority.
