# Rockwool R Value Calculator

Introduction

Calculating the R-value of insulation materials is crucial for determining their effectiveness in resisting heat flow. With the Rockwool R-value calculator, you can effortlessly determine the R-value of Rockwool insulation, aiding in efficient energy management and cost savings.

## How to Use

Simply input the relevant parameters such as the thickness of the insulation and its thermal conductivity. Click on the “Calculate” button to obtain the R-value. The formula used for calculation is explained below.

## Formula

The R-value formula calculates the thermal resistance of an insulating material. It is defined as the ratio of the temperature difference across an insulator to the heat flux through it. Mathematically, it is expressed as:

Where:

*R*is the R-value of the insulation.- Thickness is the thickness of the insulation material in meters.
- Thermal Conductivity is the measure of the ability of the material to conduct heat.

## Example Solve

Suppose you have a Rockwool insulation with a thickness of 0.15 meters and a thermal conductivity of 0.035 W/mK. Using the formula:

Thus, the R-value of the Rockwool insulation is 4.29.
