Thickened Fiberglass Insulated Flexible Duct

Our Thickened Fiberglass Insulated Flexible Duct is specially designed for HVAC systems requiring enhanced thermal insulation, condensation control, and sound attenuation.

This product features an inner aluminum foil duct, thickened fiberglass insulation layer, reinforced outer aluminum foil jacket, and steel wire helix, offering improved insulation performance compared with the standard version. It is especially suitable for projects where better temperature retention and stronger anti-condensation capability are required.

The thickened version is widely used in central air conditioning systems, fresh air systems, commercial ventilation projects, and fan coil branch duct connections. Its flexible structure allows easy installation in limited ceiling spaces and complex duct layouts.
加厚版本广泛应用于中央空调系统、新鲜空气系统、商业通风项目以及风扇线圈分支管道连接 。其灵活结构便于在有限的天花板空间和复杂的管道布局中安装。
