Panel Thickness and U-Value: Cutting Energy Loss at Industrial Doors | ABX Industrial Overhead Door
The U-Value Ladder
40 mm panels sit near 0.5 W/m2K, 80 mm panels reach 0.32 W/m2K. For a 4x4 m door in a heated hall, the difference is measurable on the energy bill within one winter.
But Panels Are Only Half
- Thermal break frames
- Sealed vision panels
- Heated door frames at cold interfaces
Our Recommendation
Spec 60 mm as the warehouse default, 80-100 mm at cold chain boundaries, and never let a frame thermal bridge undo a good panel.
