Building materials

Reinforce your waterproof or insulating membrane


Thanks to the flexibility of the manufacturing process, TENAX can realize polypropylene light weight nettings with great mechanical and tear resistance. Many of these articles are used in the building material industry. They work as support and reinforcement of waterproof and insulating membranes, they cannot corrode or oxidize.


Raw material

hPP – Homopolymer polypropylene
