The R-value of insulation can be a significant factor when it comes to which type of insulation you install in your home. It is important to recognize what makes up an insulation’s R-value, what the most effective types are, and how they impact our homes.
What Are Insulation R-Values?
An R-value in insulation measures how well a material resists the flow of heat. R-values are based on the type of thickness and density of the insulation material.
Insulation with a higher R-value is more effective at reducing heat transfer and maintaining a consistent temperature inside a building.
Insulation materials with the strongest R-values are reserved for the foundation of homes to work at their best ability.
Comparing Insulation R-values
Each type of insulation has a different R-value. A few examples (starting from lowest to highest R-values) are:
- Batts Fiberglass: R-2.9 to R3.8
- Open Cell Spray Foam: R-3.6 to R-3.9
- Foam Board: R-4.5 to R-5
- Closed Cell Spray Foam: R-6 to R-7
The R-value ratings allow our installers to determine the thickness of the insulation material needed to effectively insulate your home.
