Outdoor piping and ductwork are subjected to severe weather and climatic changes from alternating wet and dry to temperature fluctuations from below 0ºF to 150ºF or more. Many systems are subjected to ice and hail storms. In coastal areas, corrosion due to salt water spray is a major problem. As part of the product line offering, MARWRAP 40, 60 and 90 are available for use outdoors to provide broad-based chemical resistance and excellent weatherability. These systems are not affected by temperature variations, have excellent resistance to UV radiation and are considered vapor barriers as their perm rates are extremely low.

  • Do not use in temperatures in excess of 200 ͦ
