Product Description Product DescriptionFiberglass Insulated Flexible Duct for HVAC VentilationThe Fiberglass Insulated Flexible Duct is a high-performance solution for air distribution in HVAC ventilation systems, designed to provide effective thermal insulation, flexibility, and fire resistance. It consists of a durable inner aluminum duct, an intermediate layer of glass wool insulation, and a protective outer jacket made from aluminum foil.This structure effectively reduces thermal loss, prevents condensation, and improves overall system efficiency in both residential and commercial HVAC applications.Jacket:Aluminum + fiberglass Laminated (23-25 micron)Insulation Wrap:Fiberglass wool or polyester wrap (25/30mm thickness)Density of Fiberglass Wool:16kg/m3, 24kg/m3, 32kg/m3Density of Polyester:100g/m3-750gm3Inner Duct:Aluminum, reinforced with a steel wire helixMaximum Air Velocity:30 m/sWorking Pressure:Up to 3000 PaTemperature Range:-30°C to 150°CEase of CuttingNo special tools required; easy to connect to ductingFire & Pressure TestingSuccessfully tested for fire resistance and pressureFlexibilityCan be bent in any direction (small bending radius)LengthStandard length: 10 meters, customizable upon requestSpace SavingCompression ratio of 10:1InstallationEasy installation, long service life; ideal for general-purpose exhaust applicationsDuct DiameterSteel Wire (mm)Steel Wire Spacing (mm)Carton Size for 10 Meters (mm)4″ (102mm)0.930200×200×10105″ (125mm)0.930200×200×10106″ (152mm)1.037230×230×10106.5″ (165mm)1.037240×240×10107″ (180mm)1.140260×260×10108″ (203mm)1.140280×280×101010″ (254mm)1.245330×330×101012″ (305mm)1.245380×380×101012.5″ (315mm)1.245390×390×101014″ (355mm)1.245430×430×101016″ (405mm)1.245480×480×101018″ (455mm)1.245530×530×101020″ (505mm)1.245580×580×1010 Production LineComprehensive Range Of Insulated Flexible Ducts Insulated Flexible DuctAt GFI HVAC, we provide a comprehensive range of insulated flexible ducts, designed for various ventilation, air distribution, and thermal insulation needs in commercial, industrial, and residential HVAC systems.Our product line includes multiple material configurations to meet specific requirements for flame resistance, mechanical strength, and installation environments.We offer various models such as:LayerMaterial OptionsFunctionInner CoreAluminum foil, PET film, PVC layer, or multi-combinations (e.g., Aluminum + PET)Provides smooth air conveyance, resists corrosion, and maintains vapor barrierInsulationFiberglass wool or Polyester fiberDelivers effective thermal insulation and acoustic reductionOuter JacketMetallized PET (VMPET), PVC film, reinforced aluminum foil, or laminated compositesOffers fire protection, UV resistance, and moisture shielding This design provides excellent thermal insulation, fire resistance, and moisture protection, making it ideal for energy-efficient HVAC applications in both residential and commercial environments.Certifications & StandardsOur insulated flexible ducts meet various international quality and fire safety standards, including:Class A2 fire resistanceEN13501-1 M0/M1 RatingUL94 (Flame Retardancy)ISO 9001:2015 certified production processesGFI HVAC's flexible duct production facility spans 2400 square meters, equipped with 5 advanced production lines.
