R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home.

The range of R-values of insulation materials spans from materials with R-10 insulation values per inch like vacuum insulated panels and silica aerosol to below R-1 values per inch like bricks, glass, and poured concrete.
The R-value is a measure of an insulation sample's ability to reduce the rate of heat flow under specified test conditions. The primary mode of heat transfer impeded by insulation is conduction, but insulation also reduces heat loss by all three heat transfer modes: conduction, convection, and radiation.
Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness.
R-Value. Insulation is important because of its ability to reduce the amount of heat that flows between the inside and outside of your home. The ability of insulation material to reduce heat flow is called its R-value. The greater the R-value, the more this heat flow is reduced.
13 paź 2024 · R-value is a numerical measure of an insulation material’s ability to resist heat flow. The higher the R-value, the better the insulation performs. This rating is crucial for homeowners because it directly impacts energy efficiency and comfort.
An R-value tells you how well a type of insulation can keep heat from leaving or entering your home. R-value insulation ratings vary based on the type, thickness and density of the insulation material. Typically, a higher R-value means better climate control and better energy efficiency for your home. It usually means a higher price point as well.
