Dew point calculator for walls

Dew Point Calculation Calculator for Walls with Insulation – an online tool designed to help identify potential moisture condensation zones in multilayered walls. This is crucial for preventing mold formation and ensuring the durability of structures. The primary purpose of the calculator is to show the distribution of temperature and partial pressure inside the wall and calculate the dew point to prevent moisture buildup.

Main features of the calculator include:

• Dew point calculation for walls with insulation;
• Identification of potential moisture condensation zones;
• Graphical representation of temperature distribution across the wall layers;
• Graph generation for partial pressure and maximum allowable partial pressure of water vapor.

The calculator displays the wall layers, allowing users to specify up to 5 different materials. The interior is shown on the left side of the graph, while the exterior is on the right. The user inputs the number, thickness, and materials of the layers, as well as the outside and inside temperature and humidity. This enables an accurate calculation of insulation parameters and the dew point.

Main Graphs:

• Green graph – shows the partial pressure of water vapor inside the wall;
• Red graph – displays the maximum allowable partial pressure;
• Purple graph – illustrates the temperature distribution across the wall layers.

The area where the green and red graphs intersect indicates a potential moisture condensation zone, which is highly undesirable for structures. This calculator allows for the correct calculation of insulation parameters to avoid such issues.

Steps for use:

1. Select the number of wall layers;
2. Set the thickness and material of each layer;
3. Specify the indoor and outdoor temperature and humidity;
4. Click "Calculate" to get the results.

The calculator supports temperature ranges from -30 to +30 degrees and provides a user-friendly interface for graph analysis.
