Single Layer Fiberglass Insulated Air Duct

The Single layer fiberglass insulated air duct is the basic model in the glass wool insulated duct series, composed of an aluminum foil polyester outer cover, a 25mm thick yellow centrifugal glass wool insulation layer, and a single-layer aluminum foil inner duct. Specifically designed to effectively prevent heat loss/gain and surface condensation in air conditioning and ventilation ducts, the product combines significant insulation and anti-condensation effects with the inherent good sound absorption properties of glass wool core material-providing an economical and efficient universal insulation solution for most conventional air conditioning and ventilation systems. It is widely used in supply and return air ducts of household and commercial central air conditioning, ventilation duct sections passing through non-air-conditioned spaces (such as attics and suspended ceilings), and low-to-medium pressure ventilation systems with general anti-condensation requirements.

The structure of the Single layer fiberglass insulated air duct is meticulously engineered: the aluminum foil inner duct ensures airtightness of the air flow channel; the 25mm thick high-quality centrifugal glass wool insulation layer provides stable thermal resistance, effectively maintaining the duct wall temperature above the dew point to fundamentally prevent condensation; the outer aluminum foil polyester cover plays a protective and auxiliary vapor barrier role. Glass wool material not only offers excellent insulation performance but also absorbs mid-to-low frequency noise during system operation, enhancing environmental comfort. The overall flexible duct facilitates on-site bending and installation, adapting to complex building structures. Its "economical and practical" positioning makes it possible to control project costs without sacrificing core insulation and anti-condensation performance.

We recommend the Single layer fiberglass insulated air duct for standard air conditioning and ventilation projects in various residences, shops, and office buildings. It balances performance, price, and reliability, making it the ideal choice for meeting conventional insulation needs. If you're seeking a proven basic insulated duct that effectively prevents energy loss and pipe condensation, this product is your reliable partner.
