Pre-insulated Duct

Pre-Painted GI Pre-Insulated Ducts HVAC System

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 […]

Installation and Application Analysis of Phenolic Pre-insulated Duct in Large Office Building Projects

Анализ монтажа и применения воздуховодов с фенольной предварительной изоляцией в крупных офисных зданиях.

В связи с непрерывным повышением требований к энергоэффективности, защите окружающей среды и производительности систем отопления, вентиляции и кондиционирования воздуха (ОВК) в современных зданиях получили широкое распространение комбинированные системы воздуховодов для систем ОВК. Фенольные воздуховоды с предварительной изоляцией, благодаря своим превосходным теплоизоляционным свойствам и воздухонепроницаемости, все чаще используются в крупных проектах общественных зданий. В данной статье рассматривается офисное здание […]

Why Pre-insulated Ducts Are Replacing Traditional GI Duct Systems

1. Shift Toward Integrated HVAC Duct Systems In modern HVAC systems, duct selection is shifting from traditional solutions to more efficient integrated systems. Compared with traditional galvanized iron (GI) ductwork, pre-insulated duct systems are becoming a mainstream choice in HVAC applications. These systems offer improvements in structure, energy efficiency, and installation. 2. PIR/PU Pre-insulated Duct […]
