Mar-flex ArmorAir Barrier 1800i provides a seamless, 100% rubber continuous membrane around the building envelope. The barrier is impermeable to air and vapor transmission. This stops harmful moisture, but preventing structural damage is just one advantage of the ArmorAir Barrier 1800i. The membrane can also dramatically reduce energy costs due to air leakage, combat the growth of mold and earn up to 13 points toward a building’s LEED certification. A growing number of government institutions already require air barriers on their new buildings.


  • Acts as an air and rain barrier
  • Seamless monolithic membrane
