If you want to test a building material’s heat transfer, the R-value is the main metric used to measure it. Learn more about how it works and why it can help you meet compliance requirements.
How Does R-Value Work?
R-value measures a material’s resistance to heat traveling through it. The higher the score, the better it can insulate. It’s an important part of construction because this value determines factors such as energy efficiency, compliance with energy codes, and overall comfort.
How R-Value Applies to Metal Panel Systems
Insulated metal panels (IMPs) strike a balance between practicality and style. They come with a foam core that provides thermal resistance, making them a solid choice for different applications. On the other hand, non-insulated panels rely on wall assemblies and don’t provide as much protection.
However, a system’s overall R-value is not determined solely by the type of panel. It relies on:
- Panel thickness
- Core material
- Insulation quality
- Continuous insulation
The better these work together, the better your overall performance will be.
