The R-value of insulation is a value that is used to measure how well a specific type of insulation can resist heat flow. The higher the R-value, the more effective the material is at preventing heat transfer. The R-value is calculated by dividing the insulation by its K-value.
K-Value: 0.036 W/mK at 40°C

| R Value = |
*Equivalent Thickness |

K Factor (W/mk) |
*Equivalent Thickness = R2 × ln(R2/R1)
Where:
ln = Natural Log Function
R1 = inner radius of insulation (in)
R2 = outer radius of insulation (in)
R-VALUE (15 ID × 21 THK)
| 0.0285 × ln (0.0285 / 0.0075) |
| 0.036 (W/mk) |
R-value = 1.05681537664987
R-VALUE (22 ID × 22 THK)
| 0.033 × ln (0.033 / 0.011) |
| 0.036 (W/mk) |
R-value = 1.00700364684555
Compliance
SunScan SunSleeve Thermal Insulation conforms to SANS 10400-XA and has an R-value that exceeds the required R-1 value.
Installation Note
Insulation installed outside and exposed to weather must be coated with a suitable UV-resistant paint or covered with a slip cover to avoid or slow degradation.
