Numerous tools for calculating moisture conditions are available. Some of them are very simple and can be downloaded here. Others need a lot of knowledge and experience. They will briefly be described here. For more information and help, contact us.

Calculation tools
A report on tools for moisture calculations is soon completed. Order it at info@moistenginst.se. The report contains these tools:
- The vapour content at saturation, as a function of temperature. A simple equation that works well up to some +30C; also available as an Excel-file.
- Steady-state moisture distribution
- in one material with moisture dependent moisture transport coefficient. A method based on measured RH-distribution and moisture flow in a reference case. Another method based on a curve showing the moisture dependency of the moisture transport coefficientent.
- in a material combination with two groups of materials. A simple equation.
- Steady-state moisture and temperature distribution in a multi-layer structure, a so called Glaser calculation. An Excel file.
- Exchange of moisture between two materials, with different sorption curves, thicknesses and initial RH. What is the RH at equilibrium after a long time, when correctly considering the moisture history? A method, for understanding, and an equation. The equation in an Excel file.
- Non-steady-state moisture distributions, i.e. how does the moisture distribution change with time?
- A qualitative method in four steps. Download a report.
- A quantitative, manual method with 1-4 calculation cells. A calculation table.
- Computer tools. An overview of software with their possibilities and limitations.
- The software ”KFX”. 1D, 10 cells, sinus varying climate. Material properties with 3-4 parameters.
- The software ”VaDau”. 2D, 20 x 20 cells, constant or sinus varying boundary conditions, vapour content and pore water pressure as moisture transport potentials. Internal heat sources. Material properties in seven steps.
