When applying SFRM to beams beneath decking, what level of SFRM is placed in the void between beam and deck flutes?

The protective approach assumes a continuous fire-resistive layer, so you fill the void between the beam and deck flutes with SFRM by default. Filling this space prevents heat from bypassing the protection through that gap and helps maintain the required thickness and fire rating across the entire beam–deck assembly. The note “unless noted otherwise” protects against project-specific exceptions, such as drawings or manufacturer guidance that call for leaving the void unfilled, but in typical installations the void is filled to ensure reliable fire protection.
