Alumaguard® Family of Weatherproof Jacketing 


Alumaguard® - a foil faced UV resistant, vapor barrier and weather barrier membrane, self-stick, self-healing, with a zero perm rating; for use on exterior duct and piping, and vessels. Alumaguard® is a high strength 56 mil membrane laminated to aluminum foil. Its elongation eliminates the need for ‘slip joints’, as it expands and contracts with the system without rupture or leakage. Alumaguard® out performs other common exterior weather barriers, laggings, or coatings, and, by providing exceptional UV protection, weather protection, vapor barrier, and mechanical protection; and simple ‘peel and stick’ installation!

Alumaguard® Cool Wrap™ - This technology is a "green" energy saving flexible cladding available in configurations for all of our Alumaguard® family of products. Cool Wrap™ technologies includes a matte white finish, it qualifies for LEED points. Meets solar reflectance and emissivity requirements of Cool Roof Rating Council (CRRC) and California Title 24.

Alumaguard® All-Weather

Alumaguard® All-Weather -  is a marriage of Alumaguard® Lite and Alumaguard®. A product which has the self-healing properties of Alumaguard®, AND the low temperature adhesion of Alumaguard® Lite, the best of both worlds!

Alumaguard® All-Weather Cool Wrap™ - hybrid acrylic/rubberized asphalt low-temperature installation weather barrier, white high emissivity/reflectivity coated exterior self-healing membrane. Qualifies for LEED credits.

Alumaguard® Lite

Alumaguard® Lite -  is a competitive lightweight UV resistant weather barrier membrane for indoor or outdoor applications where physical abuse is not expected. Applied via acrylic adhesive (down to -10ºF), Alumaguard® Lite is a zero perm product. Alumaguard® Lite is available in smooth silver and embossed silver surface finishes.

Alumaguard® Lite Cool Wrap™ acrylic adhesive perfect barrier vapor and weather barrier, white high emissivity/reflectivity coated membrane for exterior use. Qualifies for LEED credits. Meets solar reflectance and emissivity requirements of Cool Roof Rating Council (CRRC) and California Title 24.

Alumaguard® Lite White - is a designed to be used indoors for mechanical rooms, food production areas, on pipe systems and duct-work where a true zero perm vapor barrier is preferred or other indoor applications where a glossy white appearance is desired. This solution can also be used outdoors to weather-proof exterior insulated duct-work, piping or other insulated tanks, vessels and equipment. Qualifies for LEED credits.

ZEROPERM® Vapor Barrier Family

ZEROPERM® An aluminum foil/PET vapor barrier membrane for use under jacket. ZEROPERM® is white and reverses to silver on the other giving you the option of its outward appearance.

ZEROPERM® Tapes acrylic tapes made from ZEROPERM® membrane, available in 1”, 2”, 4”, and 35” widths. Narrow width tapes are available with a release liner, or in self-wound configurations.

Insulrap™ Family

Insulrap™ 30 NG

Insulrap™ 30-NG a white, 30 mil, smooth rubberized asphalt, zero-perm, self-sealing, under-jacket vapor barrier membrane. 

Insulrap™ 30-SJ NG a white, 30 mil, scrim reinforced rubberized asphalt, zero-perm, self-sealing, under-jacket vapor barrier membrane, the obvious choice of below ambient systems.

Insulrap™ 50 NG

Insulrap™ 50 NG a black, 50 mil, smooth rubberized asphalt vapor barrier membrane used for direct burial or under jacket. Tough polyethylene gives it exceptional strength, self-healing, and low perms make it the choice for clean backfill direct buried systems. 

Insulrap™ 50-SJ NG a black, 50 mil, scrim reinforced rubberized asphalt vapor barrier membrane used for direct burial or under jacket. The embedded scrim reinforcing gives it exceptional longitudinal stability, self-healing, and low perms make it the obvious choice of below ambient systems.

Insulrap™ JB

Insulrap™ JB is a self-adhesive multi-layer white PET/FOIL/PET zero perm membrane designed specifically for LNG and Cryogenic insulation systems.

Insulrap™ "No Torch" 125  is a thick, sturdy, 125 mil, heavy duty, vapor barrier membrane for hot and cold direct burial piping and steam system applications. A sturdy triple layer product constructed with a tough outside polymer film with scrim reinforcement laminated to a thick coating of rubberized asphalt, buried inside the rubberized asphalt is another tough polymer film laminated to aluminum foil resulting in thick peel and stick membrane with excellent resistance to moisture penetration and tremendous puncture resistance making it strong enough for the toughest backfill challenges and can be used in extended temperature ranges up to 180º F. And, like the name implies, you don't need a torch to install our Insulrap™ 125 product.

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.
