Given:
2015 IBC
Type III building, 80' high.
Definition of Exterior Wall Coverings: A material or assembly of materials applied on the exterior side of exterior walls for the purpose of providing a weather-resisting barrier, insulation or for aesthetics, including but not limited to, veneers, siding, exterior insulation and finish systems, architectural trim and embellishments such as cornices, soffits, facias, gutters and leaders.
Exterior wall is fire resistance rated (gypsum board, FRTW wood studs, gypsum board). Over the exterior gypsum board, a water resistive barrier is applied (tyvek), then FRTW furring strips, and a fiber cement panel.
Question:
Is this considered a combustible exterior wall covering? Does the "exterior wall covering include everything beyond the exterior layer of the gypsum board? or just the material that is exposed on the exterior of the wall (in this case the fiber cement panel)?
Reason for question is to see if 1406 applies. I read the commentary but I did not getting any additional clarity on the matter.
