What’s more energy-efficient, single hung or double hung windows?
Energy efficiency in windows is influenced by various factors, including design, material, and installation quality. Both types of windows can be highly energy-efficient, especially single and double hung vinyl windows that are also equipped with features like Low-E coatings and tinted glass. However, double hung windows offer a slight advantage in ventilation flexibility, which can contribute to energy savings by utilizing cross-ventilation for cooling, reducing the need for mechanical cooling systems during warmer months.
