- Versatile Applications: Suitable for use in walls, ceilings, and floors, the MemBrain can be applied in various building types, including homes, commercial buildings, and renovations.
- Smart Vapor Control: The unique smart technology adapts to changing humidity levels, allowing moisture to escape when necessary while preventing excess moisture from entering the building envelope.

- Prepare the Surface: Ensure that the surfaces where the MemBrain will be installed are clean, dry, and debris-free to promote proper adhesion.
- Install Horizontally: Roll out the MemBrain horizontally with the printed side facing inward, and overlap seams by at least 6 inches for optimal performance.
