Product Data Sheet Fiberglas FLEXWRAP ASJ Description Fiberglas FLEXWRAP ASJ is a flexible insulation product made from fiberglass blanket bonded together with a thermosetting resin. The fibers are oriented to provide good compressive strength while providing flexibility during installation. FLEXWRAP ASJ is suitable for operating temperatures up to 850F (454C). Available only with ASJ facing. Key Features A cost effective alternative to larger sized pre-formed pipe insulation. Fits all pipes and equipment of 10" NPS and larger which reduces inventory requirement caused by multiple diameter requirements. The continuous blanket of material easily wraps tanks, pipes, and irregular shaped objects without the efficiency losses related to strip delamination of fabricated and segmented wrap. Low thermal conductivity compared to segmented products which means less thickness is required for equivalent heat flow. FLEXWRAP ASJ is available in rolls 48" in width and thicknesses from 1 " to 3". Standard roll lengths are given in the table above. Product Applications Fiberglas FLEXWRAP ASJ is used to insulate either hot or cold surfaces of pipes, tanks, storage vessels, ducts, and similar round or irregular shaped surfaces. All joints and facing penetrations must be sealed with appropriate pressure sensitive tape or vapor retarder mastic when the application requires a vapor seal. The product is intended for indoor use and should be weather protected for use outdoors. When determining the length required, simply determine the circumference of the piece being insulated and remember to add twice the thickness of the FLEXWRAP ASJ when calculating the diameter. If a lap is desired, add 3-4" of length and remove the additional insulation to form the lap. Take care to not cut the facing when removing the lap portion of the insulation. The FLEXWRAP ASJ is installed around the surface to be insulated, secured and either outward clenching stapled or taped. If necessary, a vapor retarder mastic is applied. Adjacent sections should be butted together and sealed with tape.

The surface burning characteristics of these products have been determined in accordance with ASTM E84. This standard should be used to measure and describe 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 which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating. Available Sizes Thickness Width Length Minimum Wrap Diameter (NPS) in. (mm) in. (mm) ft.
