The SikaMembran® system is a waterproofing and vapour control system comprising various types of membranes with optimised levels of vapour diffusion for all climatic conditions.

Durable building constructions need professional waterproofing, especially the joints between different components are highly demanding on the building designer. 
Accumulated condensation within the wall construction must be transferred outward, while the outer face must withstand rain and wind.

The SikaMembran® system is a vapour control system comprising various EPDM sheet membranes. They provide a secure and durable vapour barrier and waterproof seal at junctions between building elements. SikaMembran® system is used for curtain walls, ventilated facades and window installations.
