Choosing PIR Foam Pre-Insulated Ducts Helps to Save Space

PIR Foam Pre-Insulated Ducts maximize space efficiency, cut installation costs, and support sustainable building design in modern HVAC systems.

Phenolic Duct – High-Performance Solution for Modern HVAC

Phenolic Duct Panels Solution for Modern HVAC

GFI phenolic ducts combine insulation, airtightness, durability, and fire safety in one system. With thermal conductivity as low as 0.02 W/m·K, they deliver up to 80% energy savings, are 4–5 times faster to install, and last 20+ years—making them the smart choice for sustainable HVAC projects.

Global Demand for Pre-Insulated Ductwork in Green Buildings

Global demand for pre-insulated ductwork is rising as green buildings prioritize energy efficiency, sustainability, and HVAC performance.

PIR Alu 20mm Duct: Standard Choice for HVAC Ductwork

Among the various thickness options available, 20mm PIR Alu has become the industry standard. While thicker panels can provide slightly higher insulation, and thinner panels may reduce material usage, 20mm achieves the perfect balance between thermal performance, ease of installation, cost efficiency, and compliance with international HVAC standards. In this article, we explore why 20mm PIR Alu has become the preferred choice for HVAC ductwork worldwide.
