Dew Point Calculator

Dew Point Calculator for Insulated Walls – an online tool designed to identify potential moisture condensation zones in multilayer walls. This is crucial for preventing mold formation and ensuring structural durability. The calculator displays the distribution of temperature and partial pressure across the wall layers and computes the dew point to prevent moisture accumulation.

Main features of the calculator include:

• Calculation of dew point in insulated wall assemblies;
• Identification of potential moisture condensation zones;
• Graphical representation of temperature distribution across wall layers;
• Graph generation for both the partial pressure of water vapor and its maximum allowable value.

The calculator visualizes up to five wall layers, allowing users to specify the number, thickness, and material of each layer. The interior side is shown on the left of the graph, while the exterior appears on the right. Users provide indoor and outdoor temperature and humidity data, ensuring accurate computation of insulation parameters and the dew point.

Main Graphs:

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

The intersection of the green and red graphs highlights a potential condensation zone, which is highly undesirable for building structures. This calculator facilitates the accurate determination of insulation parameters to prevent 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 view the results.

The calculator supports a temperature range from -30°C to +30°C and offers a user-friendly interface for detailed graph analysis.
