ABSTRACT:
A fire resistant ceiling furring system comprising support joists in generally parallel alignment, furring clips attaching furring channels to the joists, furring channels in generally parallel alignment at substantially right angles to said joists thereby forming a generally grid-like configuration, said furring channels connected at grid intersection points to said joists by means of said furring clips, fire resistant gypsum ceiling panels affixed at lower attachment surfaces of said furring channels, and, mineral fiber insulation provided for substantially the full expanse of the ceiling being disposed above, and supported by, said furring channels forming a continuous layer beneath said joists. Whereby upon exposure of the fire resistant ceiling furring system to heat from below the furring channels continue to support the mineral fiber insulation and remain engaged to said ceiling panels during heat distortion by means of said furring clips retaining the furring channels. The fire resistant ceiling panels are held in place and retard cracking and contraction from said heat. Said mineral fiber insulation reduces heat transmission to said joists thereby retarding harmful distortion to said joists to inhibit flame spread and heat damage to upper building portions above said fire resistant ceiling furring system.
