NORT-FLEX PREMIUM ventilation ducts are flexible, double-layer pipes designed for air distribution in mechanical ventilation systems of residential buildings. The inner coating contains antifungal, bactericidal, and antistatic additives, while effective microbiological protection is provided by silver and silica nanoparticles. Thanks to their high flexibility and mechanical strength, the ducts allow for easy installation even in hard-to-reach places and can be safely embedded in concrete. The system features high class C airtightness, chemical and fire resistance, low flow resistance, and durability in varying weather conditions. NORT-FLEX PREMIUM is a modern solution ensuring compliance with European standards and effective operation in houses, apartments, and small-volume buildings.
