Moisture barrier prevents galvanic or chemical corrosion caused by contact of dissimilar metals and also soluble salts present in most industrial insulations. Cherrit recommends that all jacketing systems have a moisture barrier to avoid heavy maintenance cost due to galvanic or chemical corrosion.
