722.2.1.3.1 Ceramic fiber joint protection.

BC § 722.2.1.3.1

Figure 722.2.1.3.1 shows thicknesses of ceramic fiber blankets to be used to insulate joints between precast concrete wall panels for various panel thicknesses and for joint widths of 3/8 inch (9.5 mm) and 1 inch (25.4 mm) for fire-resistance ratings of 1 hour to 4 hours. For joint widths between 3/8 inch (9.5 mm) and 1 inch (25.4 mm), the thickness of ceramic fiber blanket is allowed to be determined by direct interpolation. Other tested and labeled materials are acceptable in place of ceramic fiber blankets. For SI: 1 inch = 25.4 mm. Figure 722.2.1.3.1Ceramic Fiber Joint Protection
