How Select the Right Insulation Thickness for HVAC Ductwork

 HVAC ductwork insulation plays an important role in maintaining system efficiency, controlling energy consumption, preventing condensation, and improving indoor comfort. However, selecting the right insulation thickness is not simply a matter of choosing the thickest available material. If the insulation is too thin, heat gain or heat loss can increase, condensation may occur. If it […]

What Causes Condensation on PIR/PU Pre-insulated HVAC Ducts?

Condensation and water dripping on ductwork are prevalent issues in commercial HVAC projects. Many clients hold the misconception that PIR/PU insulated panels alone can fully prevent condensation. In reality, material selection, installation workmanship, sealing details and ambient humidity all directly trigger surface sweating and dripping on ducts. This problem is especially severe in coastal, tropical and […]

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. […]
