How does Speedy work?

Speedy anti-humidity cartridges are an ingenious invention (patented throughout the world) based on the thermal exchange between the internal temperature of the wall and the external environmental air temperature (Knapen method).

The special “Speedy” anti-humidity cartridges in perforated neutral PVC create a circulation of air on the inside of the wall, making the humidity evaporate towards the outside.

The Knapen method: this principle is where hot air rises and moves towards cold air.
This allows the air flow to go through the special “Speedy” anti-humidity cartridges beneath the plaster via two small holes.
