Application

EXOPERM MONO SA 250 is a self-adhering external breather membrane designed for use on the cold side of insulation on facade wall and roof applications. It has the dual purpose of providing an air barrier as well as a vapour management system.

Suitable for:

  • Offsite and onsite construction
  • Installation on timber structures, CLT elements, OBS, steel, or concrete, masonry-type substrates
  • Facades with closed joints
  • Warm, cold and hybrid roof applications
  • Pitched or flat roofs
  • All insulation types
  • Suitable for ceiling and floor timber structures, as temporary protection during the construction phase

Self-Adhesive And Monolithic Technology

  • High-performance strong acrylic adhesive ensures seamless airtight connections, no primer or adhesive tapes required
  • Monolithic Technology offers advanced moisture vapor transmission rate (MVTR) through diffusion, creating a completely windtight, waterproof membrane that actively expels any water/humidity
