Values are nominal, subject to normal testing and manufacturing tolerances. Installation instructions 1. Measure the length of insulation required according to the fabrication guide located on the carton. 2. Cut completely through the insulation and jacket. Use a flap tool to fillet a stapling flange on one end of the insulation. 3. Each section of insulation may be secured around the pipe using either outward-clenching staples and mastic or outward-clenching staples and pressure- sensitive, vapor-retarder tape. 4. Adjacent sections must be tightly butted together and then sealed with vapor-retarder tape. Additional installation instructions Special care must be taken to vapor-seal systems operating below ambient temperatures. If indoor applications will be painted, use only a water-based latex paint. Outdoor applications require protection from weather. 1. The standard used to determine surface burning characteristics measures and describes the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment, which takes into account all of the factors that are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating.
