SPECIAL RECOMMENDATIONS
Special RecommendationsNormal use is for the external sheet of multilayer insulation (MLI). Suitable venting must be provided. · The material is available in thicknesses of 12, 25, 50 and 125 micron. · The material is available in widths up to 1220 mm. · The front surface of ITO coating can withstand light handling and abrasion, but it should be protected against excessive handling. Consult the manufacturer for further details.
