Quadzero MVT

flexible foil-faced vapor barrier

Quadzero™ MVT is a foil-faced, mass-loaded vinyl developed to meet moisture vapor transmission (MVT) resistance in liquefied natural gas (LNG) and cryogenic pipelines.

It also serves as an acoustic barrier to assist in reducing noise. It requires minimal effort to install and has been independently tested for noise and vapor transmission.

As a strong vapor and noise barrier layer solution, Quadzero™ MVT can easily be adjusted to fit around pipe insulation systems. It is flexible, tear-resistant, and is available in various sizes and weights.

Technical data

Please refer to the Technical Data Sheet (TDS) for more information.


  • Liquefied natural gas (LNG) and cryogenic pipes
  • Wrapped around other noisy pipes, valves and fan casings e.g. fluid or gas pulsation in chemical, petrochemical and waste water treatment plants
  • Compressor jackets where waterproofing is required


  • Low vapor permeability - maintaining thermal performance
  • 2-in-1 solution: vapor barrier and noise barrier
  • Simple to cut and install, providing flexibility around LNG pipes or other similar applications
  • Resistant to weather and UV light
  • Tear resistant with high tensile strength
  • Available in various weights, widths, roll lengths and sheet sizes
  • The foil facing makes it easy to bond onto other substrates using matching Tape ALR adhesive or equivalent
