Moisture can reduce duct performance and cause damage. Learn best practices for protecting PU and PIR pre-insulated ducts from condensation and water intrusion.
PU and PIR pre-insulated ducts are ideal for ceiling installations. This guide explains planning, assembly, suspension, and damper integration for efficient, airtight HVAC systems.
PU foam insulation is water-resistant, not fully waterproof. GFIDuct explains its performance in wet conditions and best practices for long-term waterproof.
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.
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.
PIR Alu duct panels offer superior insulation, minimal air leakage, and long-term durability—making HVAC systems more energy-efficient and sustainable. Ideal for modern projects.
Discover the benefits of phenolic pre-insulated duct systems. Learn why phenolic foam duct panels are replacing traditional ductwork in modern HVAC projects with superior insulation, fire resistance, and energy savings.
Rubber insulation wrap ducts and PIR foam ducts both enhance HVAC efficiency but suit different needs. Learn their differences to choose the right insulation solution for your project.
