illbruck ME003 Vapour Barrier


Suitable for most general vapour barrier/ VCL applications.


Three-ply co-extruded polyethylene (PE) vapour barrier membrane used for protecting the construction and insulation by providing a vapour and air-tight seal. High grade granulates are used as its main constituents, which does not lower the sd-value (vapour diffusion - equivalent air thickness). This consequently offers comparable diffusion resistance properties to typical 160 µm PE vapour barriers despite its lower thickness.

Features and benefits:

  • Flexible and tear resistant.
  • Highly vapour retardant.
  • Easy application due to low weight.
  • Compatible with illbruck intelligent membranes and adhesives.


Suitable for most general vapour barrier/ VCL applications.

Can be used in conjunction with:

  • OT301 adhesive - To bond the membrane to adjacent walls and floors to create a lasting air-tight and vapour-tight connection.
  • ME315, ME316 and ME317 tapes - To seal the membrane overlaps on non-porous or other suitable surfaces.
