Protect from leaks by the top roofing layer.


Provides a rational solution for the vapour barrier.


Ensures effective ventilation for the lower roofing layer.


 Offers ideal support and foundation for the outer roof definitiva.


Provides a safe foothold for fast, easy roofing work. 

A correctly installed ISOTEC system can be walked on. In case of discontinuous structures, the person walking on the structure must be careful to walk on the metal section and never step on the areas where the panels are joined together vertically, since they cannot support weight.
