Effisus VapX
Uncontrolled moisture and air movement inside building envelopes can lead to condensation, reduced insulation performance, and long-term structural damage. Effisus VapX Membrane provides a high-performance vapour control layer (VCL) for roofs, façades, and interior construction, creating a continuous airtight barrier.

Uncontrolled moisture and air movement inside building envelopes can lead to condensation, reduced insulation performance, and long-term structural damage. To prevent this, reliable vapour control is essential for maintaining airtightness and ensuring the durability and efficiency of the building.
Effisus VapX Membrane provides a high-performance vapour control layer (VCL) for roofs, façades, and interior construction, creating a continuous airtight barrier, it effectively prevents condensation in insulated areas, while its lightweight and flexible design ensures easy installation. Effisus VapX offers superior ageing resistance, dimensional stability, and tear strength, it supports long-term energy efficiency and indoor air quality.
Compatible accessories include, Effisus 2Bond GO and Effisus 2Bond DS, ensuring a complete and reliable airtight and watertight solution.
