Thermal Transmittance Calc

Thermal Transmittance Calc

By Alexey Kozlov

Thermal Transmittance Calc is a utility for construction professionals and homeowners to calculate heat loss and condensation risk in building structures on iOS.

The App DNA

What makes this app unique?

The tool serves as a quick-check mechanism for identifying dew point locations within building layers, removing the need for manual calculation during insulation planning.

For Construction professionals and homeowners planning building insulation or facade improvements.

What does it look like?

Key features

The Analyst's Read

Key takeaways for Thermal Transmittance Calc

Where is it heading?

The specialized utility market for construction planning is consolidating around tools that offer persistent project libraries and flexible material management. Thermal Transmittance Calc remains stable but exposed, as the lack of assembly-saving features will likely drive power users toward more comprehensive professional alternatives.

  • The maintenance-only release cadence prevents feature expansion, which risks losing users to more active professional tools that offer library-saving capabilities.
  • High-quality graphical rendering for condensation analysis remains a strong differentiator that retains the current user base despite the lack of updates.

The SWOT

Core Strengths
  • Graphical dew point visualization provides a clear visual check for condensation potential
Critical Frictions 2 weaknesses inside
Growth Levers
  • Integration of imperial units for material creation would improve professional workflow usability

FAQ

Is Thermal Transmittance Calc suitable for professional construction planning?
While the app provides useful quick-check graphical condensation analysis, users report that the lack of assembly-saving features and rigid material management limits its utility for complex professional workflows.
Does the app allow me to save my wall constructions?
No, current user feedback indicates that the app does not support saving custom wall constructions, which prevents users from building a library of typical assemblies for future reference.
Can I use imperial units in this app?
The app supports input toggling for dimensions in inches, but users have requested more detailed imperial unit support for new material creation to improve usability.
