R-value measures an insulation material’s resistance to heat flow. In general, the higher the R-value, the better the insulation’s performance. R-value is affected by:
- Insulation type and material
- Thickness
- Density
However, the highest R-value isn’t always the best choice for every project. For example, if your space already has some insulation, or if you live in a climate with moderate temperatures, excessively high R-values may not be necessary.
Here in Crown Point, Indiana, we are in climate zone 5, meaning homes require insulation suited to both cold winters and warm summers.
