Jul 24, 2024 · Insulation ratings are measured in R-values per inch of thickness. 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.

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.

To help you choose adequate insulation, we have summarized the R-values of 51 most common insulation materials (check the insulation R-value chart below).

Sep 30, 2023 · R-value chart gives R-values for commercial and residential insulation and roofing products. Use this table to calculate roof R-value or RSI value.

Does your attic insulation measure up? How much insulation should you install? The amount of insulation recommended for your home will vary depending on a number of factors: Where you live —Different climates require different insulation R-values.

Aug 10, 2020 · This chart shows the approximate R-value per inch of various insulation products.

Choosing the best insulation for you depends on the location and age of your home. Our R-value insulation chart lists the best options by province and zone.

The Department of Energy recommends using different insulation levels based on regional climate zones to increase energy efficiency. Locate your zone on the map and cross check it with the chart below to determine the correct R-Value for your project.

Most insulation manufacturers will first list their insulation’s R-Value for a one-inch sample, then they’ll give you a chart demonstrating the other R-Values you can achieve if you install a thicker version of their product. Let’s use the R-Value of IKO’s polyiso insulation, Enerfoil TM, …

Feb 27, 2022 · In construction, the R-value is the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation. R-values are additive.
