About the material
Protecting the structure throughout its service life
The material uses a polymer microporous membrane reinforced on both sides with polypropylene nonwoven fabric.
It protects insulation and structural elements from condensation and precipitation, releases water vapour into the ventilated cavity and reduces heat loss.
