The present invention relates safing insulation and, particularly, to safing insulation with pre-applied smoke sealant and methods for using the same. In one exemplary embodiment, safing insulation sheets are formed from individual safing insulation sections having a layer of smoke sealant applied to the upper surface of the safing insulation sections. In order to form the safing insulation sheets, individual safing insulation sections are arranged with the fibers of each individual section extending in a vertical direction and a smoke sealant is applied thereto. The smoke sealant acts to mechanically secure the individual sections of safing insulation to one another and also eliminates the need to apply smoke sealant to the safing insulation after installation. Advantageously, by pre-applying the smoke sealant to the safing insulation, the need to use spraying equipment to apply the smoke sealant to the safing insulation at a job site is eliminated.
