Steel Building Insulation Options
Understanding R-value is essential when selecting insulation. This rating measures an insulation material’s ability to resist heat transfer, directly impacting your building’s comfort and energy efficiency.
The higher the insulation blanket thickness, the higher the R-Value of the insulation. R-Value is a measurement of the effectiveness to retard or prevent the loss of heat flow. To achieve higher R-Values, two layers of insulation can be applied.
| SINGLE LAYER | R-VALUE | DOUBLE LAYER | HIGH R-VALUE |
| 2.5″ | R-8 | 3″+6″ | R-29 |
| 3″ | R-10 | 3.5″+6″ | R-30 |
| 3.5″ | R-11 | 4″+6″ | R-32 |
| 4″ | R-13 | 2.5+8″ | R-33 |
| 6″ | R-19 | 3″+8″ | R-35 |
| 8″ | R-25 | 6″+6″ | R-38 |
| 9.25″ | R-30 | 3″+9.25″ | R-40 |
| 4″+9.25″ | R-43 |
