About UvalEez

UvalEez is a precision-focused thermal calculation tool that enables architects and engineers to build construction layers, calculate U-values to BS EN ISO 6946:2017 standards, and verify building-regulation compliance with ease. Built for practising building-physics consultants, architectural technologists and designers, it turns what used to be a spreadsheet chore into a fast, repeatable workflow: define a project, assemble materials layer by layer, and instantly read off the corrected U-value, total thermal resistance and pass/fail status against approved-document limits.

UvalEez supports homogeneous and inhomogeneous build-ups, air spaces and ground-floor (ISO 13370) calculations, with branded, regulatory-ready PDF exports for client packs. A 7-day free trial of UvalEez Plus unlocks unlimited projects, watermark-free reporting and instant live recalculation — with no charge until the trial ends and the freedom to cancel anytime.

UvalEez is built and maintained by the UvalEez team, with input from building-physics professionals, to keep thermal compliance accurate, transparent and accessible for every project — from small domestic extensions to large commercial new builds.
