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.

CAVITY INSULATION
GLASS FIBER INSULATION
Composition: Glass Fiber Batts
Size: 16″ or 24″ x 48″ or 96″
Application: Cavity Installation
Compliance: ASTM C665, Type II, Class C, Category I Standard Specification for Mineral-Fiber Blanket Thermal Insulation for Light Frame Construction or Manufactured Housing
Limitations:
The National Electrical Code prohibits installation of insulation over or within 3″ (76 mm) of recessed light fixtures, unless approved insulated ceiling (IC) lighting fixtures are used.
Kraft facing is flammable and should not be left exposed. It must be installed behind and in substantial contact with the unexposed surface of the ceiling, floor or wall finish. Special care should be taken when working with an open flame.
Insulation should be kept clean and dry at all times.
