Insulrap™ 30 NG vapor barrier is the original self-healing vapor barrier membrane used on insulated piping in refrigeration, cryogenic and chemical processing applications. Insulrap™ 30 NG is a composite membrane consisting of a tough polymer film-coated with a layer of rubberized-asphalt specially formulated for this application. Insulrap™ 30 NG is considered peel and stick and self-healing and uses a disposable silicone-coated release liner. Insulrap™ 30 NG can be applied by cigarette wrapping. The silicone release liner should be removed immediately prior to the time of application. The adhesive surface of the membrane shall be applied to the insulation. Cigarette wrap applications will provide for a 2 in overlap of the membrane on itself while joints should be wrapped with 4 in butt strips. Use pressure from a roller to insure the lap is well conformed to the insulation.

- Insulrap™ 30 NG is a white, 30 mil thick and has a smooth surface
- Used on millions of square feet of insulated pipe for over 20 years with excellent success
- Self-healing, rubberized bituminous membrane seals punctures, self-sealing laps
- Saves labor and materials compared to mastic/fab/mastic coatings
- Superior elastomeric properties accommodate expansion and contraction of the substrate
- White color for improved reflectivity in the field prior to jacketing
- Low perm vapor barrier
