The Msvd Low E "Permium Performance" Myth - Actual Energy Conservation Performance Of Different Types Of Low E Glazings In Residential Windows

For moderate or heating-dominated climate zones, the "High Performance" characterisation of low solar heat gain sputtered Low E coatings is a Myth!! In fact, available glazing products with slightly greater U-factors and significantly higher SHGCs (Pyrolytic Low E), deliver significantly and drastically superior energy performance in heating dominated climate zones.
