$1.86About R-value
R-value (U-value) Application - now work out ceiling, floor or wall energy efficiency easily!
With this calculator you can check out the effective R-value and U-value for a set of materials. This is used to work out the needed amount of insulating material to meet energy efficiency regulations for floors, ceilings or walls. Useful for a builder, architect, designer or home owner looking to improve energy efficiency and so to save money. Also useful for quickly comparing the energy efficiencies of different layers.
You can select your material from a library for each layer. Proposed values can be changed freely too. With the thickness of the material the program calculates the R-value and U-value for your wall, ceiling or floor!

by Q####:
This app amounts to little more than a back of envelope calculator. The framework is there for a much better tool if the author decides to pursue increased functionality and I hope they do. Currently there is no way to pull up information on the materials selected to compare with other materials. There is no way to account for thermal bridging in an assembly, no way of adding an air space or air surface films, no metal studs, no way to add new materials.
