Overview:

A Pre-Insulated Duct (20mm) is a type of air duct system used in HVAC (Heating, Ventilation, and Air Conditioning) that combines thermal insulation and structural strength in a single product. It is designed to provide efficient air distribution while maintaining energy efficiency and noise reduction in both residential and commercial buildings.

✅ Key Features:

• Panel Structure:

  • Composed of a rigid Polyisocyanurate (PIR) or Polyurethane (PU) foam core (typically 20mm thick)

  • Coated on both sides with aluminum foil or pre-laminated aluminum sheets for durability and air-tightness

• Thermal Insulation:

  • 20mm foam thickness provides excellent thermal resistance

  • Reduces energy losses and improves HVAC system efficiency

  • Typical R-Value: Around R1.3 to R1.5 (varies by foam material)

• Acoustic Performance:

  • Damping of noise and vibration within the duct

  • Ideal for quiet environments like offices, hospitals, or residential buildings

• Air Tightness:

  • Pre-insulated panels offer low air leakage, contributing to energy efficiency and system performance

• Lightweight & Easy Installation:

  • Much lighter than traditional galvanized sheet metal ducts

  • Faster installation with simple tools and jointing systems (e.g., flanges, glue, or tapes)

  • Reduced labor and transportation costs

• Corrosion Resistance:

  • Aluminum surfaces prevent rust and degradation, especially in humid or coastal environments

• Fire Resistance:

  • Panels meet various fire safety standards (depending on manufacturer and foam used)

🔧 Applications:

• Commercial buildings (malls, offices, hotels)

• Hospitals and laboratories

• Residential HVAC systems

• Industrial ventilation and clean rooms
