Calculating R-value involves ASHRAE making measurements of heat flux over different insulation materials and determining the R-value of insulation based on how quickly (or slowly) this heat flows through the material.
This R-value thickness table is pretty easy to use. You just check which material you want to use, read off the R-value, and compare the R-value of your material with other materials. Here is a chart that illustrates graphically the differences between R-values for different insulation materials:
The R-Value formula is the measure of a material’s ability to resist heat flow. The higher the R-Value, the better the insulation. This is because it means that the material can better resist heat flow, keeping your home warmer in the winter and cooler in the summer. The formula is:
This web page calculates insulation R-values for whole floor, wall and roof constructions based on insulation R-values and the selected construction type.
6 gru 2023 · The Cellulose Insulation by Area and Depth calculator computes the number of 25 pound bags of cellulose insulation are needed to cover an area to achieve a specified R Value. It also provides the depth of insulation needed and estimated cost based on the price per bag of cellulose insulation. INSTRUCTIONS: Choose units and enter the following:
