Monolithic Membrane 6125®The industry’s first hot fluid-applied, rubberized asphalt membrane.

Monolithic Membrane 6125® is the original hot fluid-applied rubberized asphalt membrane. Developed in the early 1960s, it improved both the quality and durability of waterproofing systems. MM6125® quickly became the premier choice for commercial buildings throughout the world.

Roof less.
Save more.

Lasting two-to-three times longer than a typical built-up roofing system, monolithic membrane 6125® assemblies equate to not only fewer re-roofs, but also less waste going into landfills, and less demand on our natural resources.

Beyond sustainable.

The environmental benefits of MM6125® is well understood. There are also many economical benefits.

Economical benefits of an MM6125® assembly:

  • Increase roof life expectancy
  • Lower maintenance
  • Create additional usable space
  • Allow owners to receive government incentives
  • Improve occupant productivity and collaboration

Environmental benefits of an MM6125® assembly:

  • Fewer re-roofs
  • Less utilization of landfill
  • 40% post-consumer recycled content
  • Design flexibility to accommodate Garden Roofs and Stormwater Management
  • Contributions to several LEED® and Living Building Challenge credits

Designed for people.

Roof spaces are a key design element in a building’s ability to reenergize the connection between living and working—contributing to comfort, safety, and productivity.

Benefits utilizing roof spaces:

  • Provides additional space for gathering
  • Therapeutic and healing environments for healthcare and hospitals
  • An alternative to “Indoor air” work environment
  • Can be up to 50 degrees cooler than traditional roofs

Turning commercial roofing upside down.

By simply reversing the insulation and membrane placement – insulation on top of the membrane rather than beneath – many roofing problems can be easily eliminated.

Engineered for better design flexibility
and performance.

The membrane is below the insulation, a reverse order of traditional roofing materials, offering a better design solution for high-performance roofs, garden roofs, rooftop plazas, water features and other multi-use rooftop applications.

More than
a protective roof.

Garden Roof® and stormwater management assemblies offer architects and owners more than a building that doesn’t leak.

Environmental benefits of a vegetated roof:

  • Mitigates urban heat island effect
  • Re-creates habitat
  • Oxygen production
  • Reduces CO2 levels
  • Noise reduction
  • Reduction of dust and smog

Environmental benefits of stormwater management assemblies:

  • Volume reduction
  • Time delay of water runoff
  • Filtering particulate before the city’s system
  • Reduction of downstream infrastructure and maintenance costs
