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. MTO (Made to Order). Product availability subject to change. View product guide for details. All rolls are 48" (1,219 mm) wide. Installation instructions 1. When determining length requirements, remember to add twice the thickness of Flexwrap insulation to the diameter when calculating the circumference of the piece being insulated. 2. If a lap is desired, add 3" to 4" of length and remove the additional insulation, taking care not to cut the facing, to form the lap. 3. Flexwrap insulation is installed around the surface to be insulated, secured and either taped or stapled with outward-clenching staples. If necessary, apply a vapor-retarder mastic. Additional installation instructions Adjacent sections should be butted together and sealed with tape. Use of bands or impalement pins for securement purposes is permitted but should be sealed as necessary with mastic. When the application requires a vapor seal, all joints and facing penetrations must be sealed with appropriate pressure-sensitive tape or vapor-retarder mastic.
