Insulation K Value Calculator

Formula

To calculate the Insulation K Value (K):

\[ K = \frac{T}{R} \]

Where:

\(K\) is the Insulation K Value in BTU-in/hr-ft²-°F
\(T\) is the Thickness in inches
\(R\) is the R-Value

What is Insulation K Value?

The Insulation K Value is a measure of the thermal conductivity of a material. It indicates how well the material conducts heat. A lower K value means better insulation properties, as it indicates less heat transfer through the material.

Example Calculation 1

Let's assume the following values:

Thickness (\(T\)) = 2 inches
R-Value (\(R\)) = 10

Using the formula:

\[ K = \frac{2}{10} = 0.2 \text{ BTU-in/hr-ft²-°F} \]

The Insulation K Value is 0.2 BTU-in/hr-ft²-°F.

Example Calculation 2

Let's assume the following values:

Thickness (\(T\)) = 3 inches
R-Value (\(R\)) = 15

Using the formula:

\[ K = \frac{3}{15} = 0.2 \text{ BTU-in/hr-ft²-°F} \]

The Insulation K Value is 0.2 BTU-in/hr-ft²-°F.
