32、se temperature of some facings and adhesives willbe lower than the maximum use temperature of the insulation.For example, usually galvanized hexagonal wire-woven net-ting and tie wires or stitching perform well under continuousexposure to temperatures up to 392F (200C). Exposure totemperatures above

33、 this limit will cause the outer free zinclayer to peel. Though there are potential or occasional concernsfor corrosion conditions at various temperatures, galvanizedwire, stitching, or facings are not recommended for tempera-tures above 500F (260C). In addition, the user of thisspecification shall
