ME003 is a 3-ply polyethylene membrane which has been developed as a vapour barrier. Compatible with illbruck intelligent window membranes and adhesives.


This innovative 3-ply co-extruded PE vapour barrier membrane meets virtually all the demands of professional practice and protects the construction and insulation by providing a vapour and airtight seal. High-grade granulates are used as its main constituents, which does not lower the sd-value (vapour diffusion-equivalent air layer thickness). Consequently, this high-grade product offers comparable diffusion resistance properties to typical 160 μm PE vapour barriers, despite its lower thickness.
