Advantages
Acoustically Efficient: Reduces transmission of sound through roofs, ceilings, floors and walls.
Fire-Resistant: Flame Spread of 25 or less and Smoke Developed of 50 or less. 
Noncombustible: Unfaced I/S 150, I/S 300 and I/S 600 are non combustible.
Moisture-Resistant: Vapor-retarder facings resist water vapor transmission.
Noncorrosive: Prevents acceleration of corrosion to pipes, wiring and metal studs.
Durable: Will not rot, mildew or otherwise deteriorate, preventing slumping and uninsulated voids.
Easy to Handle: Lightweight; maintains its physical integrity during handling.
