Pre Insulated Duct Panel Thickness Selection Guide

Guide de sélection de l'épaisseur des panneaux de conduits pré-isolés

Improper selection of the thickness for pre-insulated duct panels can easily lead to problems such as condensation, increased airflow noise, and excessive cooling loss. GFI has compiled reference standards for PID panels thickness selection in four major scenarios“shopping malls, hospitals, factories, and equipment rooms” based on airflow velocity conditions. PID Model Selection Note：This table applies […]

GFI Standard Sealed Molded PIR Pre-insulated Duct Panel

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. […]

What Is Duct Board Made Of

Polyurethane Insulation Boards vs Traditional Insulation Materials

In modern construction and HVAC systems, the selection of HVAC insulation panel materials directly affects building energy efficiency, system performance, and long-term maintenance costs. As building energy standards continue to increase, traditional insulation materials gradually show certain performance limitations. As a result, engineers and project developers increasingly adopt high-performance insulation materials such as polyurethane insulation […]
