What is the R-value and K-value of thin brick?

Approx. 0.1 R-value per 1/2" thin brick. Thin clay brick offers minimal insulation.

The thermal resistance (R-value) and thermal conductivity (K-value) of materials are key factors in assessing their insulating properties.

R-value: This measures a material's resistance to heat flow; higher values indicate better insulation.

K-value: This represents a material's thermal conductivity; lower values mean better insulation.

For 1/2-inch thin clay brick:

  • R-value: Approximately 0.1. Standard clay brick has an R-value of about 0.2 per inch of thickness. Therefore, a 1/2-inch thick brick would have an R-value of roughly 0.1.

  • K-value: Approximately 5.0 W/m·K. The thermal conductivity of clay brick varies based on composition and density, but a typical value is around 5.0 W/m·K.

These values indicate that thin clay brick offers minimal insulation. For improved thermal performance, consider adding dedicated insulation materials to your wall assembly.
