EI 30 Certification
It has all the certifications required by the CTE in this type of applications, being certified EI 30 in interior and exterior fire conditions, both for vertical assemblies, EI 30 ve (i↔o), and horizontal assemblies, EI 30 ho (i↔o)
Inspection and cleaning
The inspection and cleaning registers have been specifically designed for this application, and have been tested and certified together with the duct, in accordance with the requirements of the CTE
Resistance and robustness
The design of the parts provides them with high stability and mechanical resistance, also guaranteeing a reduced thermal bridge and the maximum air tightness classification
