Technical Reference
Configurator Methodology & Validation
Every output value in the THERMGLASS configurator suite is derived from published engineering standards. This page documents the calculation methods, input assumptions, boundary conditions, and known limitations for each tool.
The five THERMGLASS configurators are specification-assistance tools, not certified rating instruments. Outputs are indicative values derived from published standards and should be verified by independent testing before use in permit submissions, procurement contracts, or certified energy models.

All configurator outputs are indicative values derived from published engineering standards and internal THERMGLASS product data. They are not certified ratings and should not be used in permit submissions, procurement contracts, or certified energy models without independent verification. THERMGLASS accepts no liability for decisions made solely on the basis of configurator outputs. Contact THERMGLASS for project-specific engineering support.
