Energy-Efficient Glazing Basics

摘要

Windows connect building occupants to the outdoors via daylight, views, and natural ventilation while protecting them from the elements. Or, at least that's the ideal. Even so, in many older buildings (and even in some newer ones), windows fail to weatherize occupied space and are prone to water leakage, condensation, or noise transmission. The consequences can include high energy bills, occupant discomfort, and water damage. For this reason, window improvements are in high demand; while upfront costs can be a barrier, overall cost savings can be achieved if improvements are made with energy efficiency in mind.
