Do Moss Walls Affect Humidity?

This is one of the most common, and understandable, questions we're asked.
Will a moss wall introduce moisture into an interior space?
The answer is simple: no, it won’t.
Understanding How Preserved Moss Works
Unlike living plant walls, preserved moss is no longer actively growing.
Through a specialized preservation process:
-
The plant’s natural sap is replaced with a glycerin-based solution
-
The material retains its softness and color
-
It requires no water, soil, or sunlight

What This Means for Your Environment
Because preserved moss is not alive:
-
It does not release moisture into the air
-
It does not create condensation
-
It does not impact indoor humidity levels
Ideal Conditions for Longevity
For optimal performance, preserved moss walls should be installed in controlled indoor environments, ideally within a 40-60% humidity range.
Outside of that, they remain stable with minimal attention.
A Low-Risk Way to Introduce Biophilic Design

Preserved moss walls offer the visual and emotional benefits of greenery without the maintenance requirements or environmental concerns associated with living systems.
For designers, architects, and property owners, that makes them a reliable and effective solution.
