Maximizing HVAC Efficiency: The Impact of Insulation Thickness
Energy efficiency in ductwork isn't just about sealing leaks; it's about optimizing thermal performance. To do that, you need to master the K, R, and U values.
We’ve created a quick-reference infographic to simplify these core insulation concepts. Using GDI pre-insulated panels as the baseline, you can clearly see the relationship between thickness and performance.
The key takeaway for better insulation:
✅ Lower U-Value (less heat escapes)
✅ Higher R-Value (greater resistance to heat flow)
When you upgrade from a 20mm to a 30mm panel, you are directly increasing your R-value from 1.00 to 1.50, and dropping your U-value from 1.00 to 0.67. This leads to reduced energy consumption and operational costs.
How do you prioritize insulation values in your efficiency specifications?
