SikaMembran® Outdoor plus is an EPDM sheet membrane with a low vapor diffusion resistance (sd value 3 m) and is thus recommended on the cold side if there is an extremely high vapor pressure on the warm side. The SikaMembran® system is a high-performance vapor control system comprising of various EPDM sheet membranes providing vapor control layers and waterproof barriers for curtain walls. They are suitable for most climatic conditions in combination with the appropriate adhesive.
