Install NSi FireStop Mineral Wool to the minimum 25% to 33% compression
required by the tested firestop system. Compression must always be perpendicular to
the grain. Butt adjacent sections of NSi FireStop Mineral Wool tightly against each other. Leave
no voids. NSi FireStop Mineral Wool is the recommended backing material for NSi FireStop
Silicone, Silicone SL and Intumescent Caulk. Determine the depth of firestop sealant required and
recess the mineral wool to the appropriate depth.
