Johns Manville Mineral Wool Safing prevents smoke and flames from passing through openings in fire-rated assemblies. It is designed to provide a fire-rated seal when installed between the spandrel panel and floor slab in commercial curtainwall systems. Safing is ideal for interior cavities and easily cut with a knife for quick installation and easy sizing for a snug fit.
Mineral wool is lightweight and ideal for sound control throughout interior cavities
