Building performance
and window performance.
NatHERS assesses the thermal performance of a home as a whole. Window and door performance data — including U-Value and solar heat gain coefficient (SHGC) — forms part of that broader building-energy assessment.
For window and door manufacturers, SIIGMATIC's primary product-energy services are WERS ratings and window/door thermal simulation.
