Insulation

Insulation that is specified in interior systems is there generally for acoustical performance. The insulation is installed in the cavity created by the cold-formed steel framing. The insulation comes in three types of materials. They are glass fiber, mineral wool or spray-in foam insulation.

Note:  The limitations provided here are taken from appropriate building product manufacturer's source.  For more and the latest information relative to these limitations, it is recommended to contact either the representative association or a specific building product manufacturer.   A partial list of associations, and their links is provided on the home page of this site.
