47、The properties of spray-applied polyurethane thermal insulation may vary depending on such factors as the thickness of thefoam sprayed, the temperature and type of substrate, the ambient temperature and humidity, the number of spray passes, and theoutput of the equipment. The properties may also var

48、y depending on different manufacturers liquid components.X1.2 Spray-applied polyurethane thermal insulation generally exhibits its highest thermal resistance at the time of manufacture.The thermal resistance may be significantly influenced by installation and service-related variables such as age, f

49、oam thickness,type of coating, environmental conditions and mechanical abuse. These variables may cause the thermal resistance to be reducedfrom measured initial values.X1.3 The application of a suitable vapor retarder may be required in conjunction with this insulation. In exterior installations,coatings or coverings are necessary for protection from the elements and should be applied on the same day.X1.4 Rigid-cellular polyurethane thermal insulation is combustible to varying degrees when exposed to an ignition source
