What is R-Value & How Does It Affect My Comfort?
With insulation comes R-values, or resistance values, which simply is used to measure how effective the insulation is resisting heat flow. These values fluctuate based on the geographic regions. Different insulation materials have different thicknesses per inch. The thicker the insulation, the more it resists heat transfer. Fiberglass Insulation: 2.7-3 per inch Cellulose Insulation: 3.4-3.8 per inch Spray Foam Insulation (closed-cell): R6 Rule of Thumb: The lower the R-value,
