Passive Purple External: Intelligent Weather Protection.
During the podcast, Adam demonstrates how Passive Purple External, our intelligent liquid-applied weather membrane system, delivers exceptional airtightness, durability and façade protection for projects of all shapes and sizes.
Designed for modern high-performance construction, Passive Purple External is:
-
Spray or roller applied
-
A super tough, watertight vapour control membrane
-
Highly resistant to UV exposure
-
Engineered for long-term weatherproofing performance



Intelligent Vapour Control Technology
What sets Passive Purple External apart is its intelligent vapour permeability.
Its advanced formulation allows vapour to escape where required, reducing the risk of trapped moisture within the structure, while simultaneously maintaining a fully airtight building envelope.
This balance of:
-
Airtightness
-
Breathability
-
Weather resistance
-
Façade durability
makes it ideal for Passive House, Passivhaus, and high-performance building projects.
Built for Performance, Designed for Simplicity
Whether applied by spray for large façades or roller for smaller details, Passive Purple External offers:
-
Fast installation
-
Seamless coverage
-
Reliable airtight performance
-
Long-term durability
