1. Structure and Physical Characteristics
Highly stretchable and bendable flexibility
Built-in galvanized steel wire spiral frame, freely stretchable,able, and twistable, suitable for tight ceiling spaces, multiple turns, and equipment relocation scenarios. Installation requires no large quantities of elbow fittings, saving construction time.
Three-layer protection
Inner aluminum foil: Strong airtightness, resistant to airflow erosion, no air leakage, corrosion-resistant, and no leakage when transporting hot and cold air;
Middle Owens Corning fiberglass insulation: High-density flame-retardant insulation layer, with built-in antibacterial and noise reduction functions;
Outer aluminum foil: Moisture-proof and vapor-, isolates wall moisture and condensation, preventing the insulation from getting damp and losing effectiveness.
