General InformationX1.1 The properties of spray-applied polyurethane thermalinsulation may vary depending on such factors as the thickn
44、essof the foam sprayed, the temperature and type of substrate, theambient temperature and humidity, the number of spray passes,and the output of the equipment. The properties may also varydepending on different manufacturers liquid components.X1.2 Spray-applied polyurethane thermal insulation gener-
45、ally exhibits its highest thermal resistance at the time ofmanufacture. The thermal resistance may be significantlyinfluenced by installation and service-related variables such asage, foam thickness, type of coating, environmental conditionsand mechanical abuse. These variables may cause the thermal
46、resistance to be reduced from measured initial values.X1.3 The application of a suitable vapor retarder may berequired in conjunction with 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
