What is R value and K value?

The performance of your insulation can be measured in terms of both “r value” and “k value,” but these numbers tell you two different things. K-values measure how much heat passes through a material, while R-values measure how well the material prevents heat from passing through.

The performance of your insulation can be measured in terms of both “r value” and “k value,” but these numbers tell you two different things. K-values measure how much heat passes through a material, while R-values measure how well the material prevents heat from passing through. Bottom line: for stronger insulation, you want a low K-value and a high R-value! Remember, when comparing different insulation types, it helps to understand a bit more about what these values mean so you can judge how much better one type of insulation performs over another.

What K-Values Mean

K-values measure conductivity. Good conductors have higher K-values, and poor conductors have lower K-values. When insulation is your concern, you want a low K-value. In terms of insulation for industrial and mechanical purposes, K-values are important because they tell you how well the material insulates when it has a thickness of 1 inch. If you know the K-value, you can determine the appropriate thickness you need for your insulation.

Here’s a more specific explanation of how K-values are calculated:

The formula is BTUs per hour conducted through a 1-inch-thick, 1-square-foot piece of the material. In practice, this means a low K-value material lets less heat pass through it. In that sense, it tells you quite a bit about how well the material insulates. Note: Thickness does not affect K-value. The measurement tells you about the performance of the material, not the actual product you might purchase. If two kinds of insulation have the same K-value, they’re equally good conductors—but the thicker one will insulate better.

What R-Values Mean

R-values measure insulation. Higher R-values indicate that a material insulates better.

At home, your windows and fiberglass insulation carry an R-value rating to indicate how well they keep out exterior temperatures and keep in heating and air conditioning. For industrial and mechanical insulation, you may also see these same R-values used. The important thing to know is that insulation R-values indicate the “thermal resistance” of the material—how well the product prevents heat energy from passing back and forth. Note: Thickness affects R-values. For example, you can look at a certain kind of fiberglass insulation product. The 1-inch-thick product will have a certain R-value, and the 2-inch-thick version of the same product will have twice the R-value. When you have multiple layers—such as fiberglass insulation covered by a PVC jacket—you can add up the R-values of each layer to determine a total R-value for the whole system. For many practical purposes, you can find out a minimum K-value or R-value, or an optimal range to buy. If you aren’t sure what ratings you need, contact us here at Breeding Insulation and we can help you determine the right materials for every application!
