Vapor Barriers

Polyguard's Mechanical Products Division specializes in Duct and Pipe vapor barriers with standard and "peel 'n stick" vapor barriers. Insulation vapor barriers both rubberized bitumen (self-healing), acrylic adhesion systems, or tape on systems; we have the vapor barrier for your installation.

ZEROPERM® Products:

ZEROPERM® is an aluminum foil/PET vapor barrier membrane for use under jacket. ZEROPERM® is white on one side, and silver on the other giving you the option of its appearance.

ZEROPERM® Tapes Two types of tapes are available to complete the field installation. 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, is used on valves and fittings.

Insulrap™ Family of Products:

Insulrap™ 30-NG products: is the "Next Generation" of self-healing vapor barrier membranes used as a moisture and vapor retarder under mechanical jacketing on insulated piping systems used in ammonia refrigeration, oil and gas, LNG, cryogenic and chemical processing applications. I-30-NG products are comprised of a white, 30 mil thick, vapor barrier composite membrane consisting of a tough polymer/foil laminate film coated with a layer of rubberized-asphalt specially formulated for use in these applications. Our "peel and stick" product consists of a built-in disposable silicone-coated release liner to make application quick and easy. I-30-NG offers exceptional longitudinal stability, self-healing, and zero perms making it the obvious choice of below ambient systems.

Insulrap™ 30-NG offers a smooth finish that will stretch and flex to accommodate movement of the substrate.

Insulrap™ 30-SJ NG offers fiberglass scrim reinforcement embedded in the laminate using a process that minimizes the scrim profile providing extra strength, durability and enhanced lap adhesion.  

Insulrap™ 50-NG productsis the "Next Generation" of self-healing vapor barrier membranes used as a moisture and vapor retarder under mechanical jacketing on insulated piping systems used in ammonia refrigeration, oil and gas, LNG, cryogenic, tanks and vessels, and chemical processing applications. I-50-NG products consist of a black, 50 mil thick, vapor barrier composite membrane consisting of a tough polymer film coated with a layer of rubberized-asphalt specially formulated for use in these applications. Our "peel and stick" product consists of a built-in disposable silicone-coated release liner to make application quick and easy. I-50-NG offers exceptional longitudinal stability, self-healing, and zero perms making it the obvious choice of below ambient systems. Can be used in direct burial applications where backfill is uniform, clean and free of rocks and debris.

Insulrap™ 50 NG has is smooth, tough, polyethylene laminate providing exceptional strength, self-healing, and true zero perm performance.
Insulrap™ 50-SJ NG has a fiberglass scrim reinforcement embedded in the laminate using a process that minimizes the scrim profile providing extra strength, durability and enhanced lap adhesion with exceptional longitudinal stability, self-healing, and is zero perm making it the obvious choice of below ambient systems.
 
Insulrap™ JB
Insulrap™ JB is the same product as Insulrap™ 30-SJ-NG with a butyl twist. The same zero perm film, the same white imbedded scrim, all put together on a butyl based compound. Cold weather tack and flexibility are what butyl is all bout, designed specifically for the LNG and cryogenic markets.
 
Insulrap™ "No Torch"™ 125 is a vapor barrier membrane for direct burial steam system applications. A thick triple layer product, utilizing the same film as Alumaguard®, sandwiched between layers of rubberized asphalt, topped with black scrim reinforced, zero perm film. You don’t need a torch to install our 125 mil product. It's thick, tough and durable enough for your most challenging direct burial applications.

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 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.

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


Polyguard's Mechanical product line also features the RG-2400® of corrosion gels; stop and prevent Corrosion Under Insulation (CUI). Alumaguard® Weatherproof Jacketing & Cladding Products, and Dow® Styrofoam XPS PIB.
