43、nformation)X1. General InformationX1.1 The properties of spray-applied polyurethane thermalinsulation may vary depending on such factors as the thicknessof the foam sprayed, the temperature and type of substrate, theambient temperature and humidity, the number of spray passes,and the output of the e

44、quipment. The properties may also varydepending on different manufacturers liquid components.X1.2 Spray-applied polyurethane thermal insulation gener-ally exhibits its highest thermal resistance at the time ofmanufacture. The thermal resistance may be significantlyC 1029 05a3influenced by installati

45、on and service-related variables such asage, foam thickness, type of coating, environmental conditionsand mechanical abuse. These variables may cause the thermalresistance to be reduced from measured initial values.X1.3 The application of a suitable vapor retarder may berequired in conjunction with

46、this insulation. In exterior instal-lations, coatings or coverings are necessary for protection fromthe elements and should be applied on the same day.X1.4 Rigid-cellular polyurethane thermal insulation iscombustible to varying degrees when exposed to an ignitionsource or high temperatures, or both.
