Vapor Proofing Membranes

Durable building constructions need professional water proofing, 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 vapor control system comprising of various EPDM sheet membranes. They provide a secure and durable vapor barrier and waterproof seal at junctions between building elements. SikaMembran® system is used for curtain walls, ventilated facades and window installations.

Benefits

• Highly flexible made of special EPDM
• Fast, easy and secure application even in corners
• Suitable for all climatic conditions
• Very resistant to high wind loads (up to 10 kPa)
• Suitable for uneven sub­strates (blowholes in concrete), leveling of substrate by adhesive
  

Sika and the Fraunhofer Institute in Germany have made various simulation to prove performance of the vapor control concept with Sika Membran® System in four different climatic zones.

The simulation showed no humidity accumulation right after the construction phase nor during the following years. This shows that with the Sika Membran® System, the wall keeps breathing.
