REGIONAL TRADITION
Straight edges and diamond shape make the Alterna range a new solution for roofs and wall cladding making it very respectful to local traditions.

AUTHENTICITY AND CHARACTER
Alterna can be used in either new or renovation construction thanks to its original shape, its low density per square meter and its minor load on framework.
