Dew Point & Surface Condensation Calculator

How it works

Calculate dew point from air temperature and relative humidity and compare it with a surface temperature.

Practical use

Use verified material data and project geometry. Treat results as planning estimates and compare them with the energy/thermal requirements that apply to the project.

• Keep units consistent with the source information.
• Use project-specific densities, pack sizes and coverage rates where provided.
• Round purchasing quantities to supplier packaging and delivery rules.
