Matériaux de conduits pré-isolés GFI

Pre-Painted GI Pre-Insulated Ducts

Système de chauffage, ventilation et climatisation (CVC) avec conduits pré-peints et pré-isolés en acier galvanisé

Outdoor and semi-outdoor ventilation systems in coastal and tropical high-humidity regions continuously face harsh environmental conditions. Including salt-laden air, high relative humidity, and significant day-to-night temperature fluctuations.When contractors use conventional PIR/PUR pre-insulated duct systems in coastal outdoor or semi-exposed applications. Standard aluminum foil facings may not provide adequate protection against prolonged salt-spray exposure. Even minor […]

PU PIR vs Phenolic Duct Panels

Panneaux de conduits PU/PIR vs panneaux phénoliques : quelle est la véritable différence ?

Comparez les panneaux de gaines pré-isolés en PU/PIR et en résine phénolique pour les projets de CVC, notamment leurs performances thermiques, leur comportement au feu, leur fabrication et leur choix pratique. Les panneaux en PU/PIR et en résine phénolique servent tous deux à fabriquer des gaines de CVC légères et pré-isolées. Chaque panneau combine une âme en mousse rigide et des parements protecteurs, ce qui permet de réaliser l'enveloppe de la gaine et l'isolation thermique en une seule étape de fabrication. […]
