R-Value & Hygrothermal Calculator

Science-driven comfort, tailored to your building project. Calculate thermal resistance and moisture risk to ISO 6946 & DIN EN 15026.

💡 What is R-Value?

R-value measures thermal resistance - how well a material resists heat flow. Higher R-values mean better insulation performance.

💧 Why does moisture matter?

Moisture in building assemblies can lead to mold, rot, and reduced insulation performance. Our calculator helps identify condensation risks.
