Double-pane glass typically lets in about 40-70% of blue light per square foot. This percentage varies based on the glass type. High-performance coatings and tints can decrease blue light transmission, improving UV ray and solar radiation protection while enhancing energy efficiency in buildings.
Energy-efficient double-pane windows often feature low-emissivity (low-E) coatings. These coatings reduce heat transfer and also help filter blue light. The low-E coating reflects some blue light while still allowing beneficial natural light to brighten your space. When calculating energy efficiency, it is crucial to consider both light transmittance and insulation properties.
Understanding how much blue light comes through double-pane glass enables homeowners to make informed decisions about window installations. This consideration helps in achieving a balance between brightness and energy efficiency.
As we explore further, we will discuss the health impacts of blue light exposure and additional measures for optimizing indoor lighting. This knowledge will assist in creating a healthier living environment while maximizing energy savings.
