Effisus VapX Membrane

1-layer vapour control layer (VCL)

Effisus VapX Membrane is a one-ply vapour control layer (VCL) for roofs, facades, dry and general construction indoors in order to build an airtight barrier for the protection of construction according with DIN 4108.

The carefully selected raw material assures superior ageing resistance, dimensional stability, length and crosswise as well as high rip resistance. The sd value of 100m effectively prevents the building of condensate in the areas of insulated construction.
