Insulrap™ No Torch 125 NG

Insulrap™ "No Torch" 125 NG is a 125 mil self-adhesive vapor barrier and waterproofing membrane for installation over insulation on hot or cold underground piping systems.

Insulrap™ "No Torch" 125 NG is a multi-layered "peel and stick" product providing maximum protection of buried insulated pipe systems with labor saving ease of a peel and stick application. The outer film is a multi-laminate foil and polyester, high strength with an embedded polyester scrim pattern for extreme strength.

Insulrap™ "No Torch" 125 NG will expand and contract to accommodate normal pipe movement and is resistant to chemicals, acids, and alkalis.

Insulrap™ "No Torch" 125 NG will tolerate higher insulation surface temperatures than our other burial membranes. The design and engineering of insulation on buried steam lines is critical to the success of the system; special care must be taken in the design of these systems, consult the insulation manufacturer for more information. 


Companion Products:

InsulShield™ is a puncture resistant "insurance" jacket installed over Insulrap™ products for in direct burial in ROCKY conditions. If you are not doing a sand backfill, you need to protect the Insulrap™ with the extra 400 psi of puncture resistance provided by InsulShield™.

Outerwrap™ is used on clean (and rocky) backfills to prevent damage to the Insulrap™ from soil stress. All that fresh dirt you piled over the pipe is going to settle, without a ‘slip-sleeve’ to absorb that movement, you will have issues.

Low Temperature Solvent Based Activator is used as a primer when applying Insulrap™ products in temperatures below 50º F.

VaporGuard™ Tape is a self-adhesive butyl sealant for use in vapor stops, expansion joints, and terminations on ammonia systems. 

ZEROPERM® Tapes Two types of tapes are available to complete field installations, both use a high quality, acrylic adhesive with excellent cold weather performance. ZEROPERM® A Tape has a kraft release liner and is typically used for sealing longitudinal and circumferential laps. ZEROPERM® Self-Wound Tape has no liner, and is used on valves and fittings.
