Insulation jacketing is an outer covering that is wrapped around tubing or pipe insulation to shield the insulation from moisture, wear, and mechanical damage. Insulation jacketing plays a vital role in the productivity and effectiveness of the mechanical insulation.
When selecting a jacketing one must consider the mechanical, chemical, thermal, and moisture conditions of the installation as well as cost and aesthetics requirement.
Facings are fastened to insulation materials during the manufacturing process. They are used on insulation to protect and hold the insulation together. Your climate and where and how you are installing the insulation will determine what type of facing you will need.
