Well-insulated windows and doors: The U-value, explained.
When comparing energy-efficient windows, the U-value is often mentioned. The U-value is the thermal transmittance coefficient. It is used to evaluate a window's heat insulation and indicates the amount of energy that flows through a 1 sqft surface in 1 hour. The lower this value is, the higher the heat insulation. Compared to conventional, single-glazed window with U-values averaging 0.43, our windows can reach down to 0.13.
