This specification describes the physical requirements for aluminum jacketing for thermal and acoustical insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. Insulation jacketing made from other materials such as PVC, fiber reinforced plastic, mastics, or stainless steel, or the details of thermal or acoustical insulation systems, are beyond the scope of this specification. The standard requires the designer of an insulation system, after determining the system requirements, to specify the appropriate aluminum jacketing. It addresses the classification of aluminum jacketing, materials and manufacture, physical properties, dimensions and permissible variations, workmanship, finish and appearance, requirements of aluminum jacketing, test methods, sampling and inspection as well s rejection of defective material, certification, product marking, and packaging. Definitions of terms specific to this standard are provided, including jacketing, lagging, cladding, and moisture retarder (moister barrier).

1.1 This specification covers aluminum jacketing for thermal and acoustical insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. It does not cover insulation jacketing made from other materials such as mastics, fiber reinforced plastic, PVC, or stainless steel nor does it cover the details of thermal or acoustical insulation systems.

1.2 This specification provides physical requirements for aluminum jacketing for thermal and acoustical insulation. Guide C1423 provides guidance in selecting jacketing materials and their safe use.

1.3 This is a material specification and does not imply any performance of the installed system using the materials specified herein. For information about installation of aluminum jacketing, see (1).²

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
