From simple U-value to complete project documentation — one platform.
Calculate U-value for pipes and flat surfaces. Supports multiple layers, wind conditions and different environments.
Compare all materials for the same pipe. View thermal conductivity, price and performance side by side.
Find minimum thickness for safe surface temperature (≤ 60 °C). Document HSE requirements.
Find optimal thickness for lowest total cost over the lifetime. Energy price, investment and maintenance.
Calculate how long before water in pipes freezes. Critical for outdoor piping and process plants in cold climates.
Document the carbon footprint of insulation choices. Show CO₂ reduction per metre of insulated pipe.
Whether you design, install or procure — IsoCal makes the job easier.
