Windows provide natural ventilation indoors by allowing daylight and exterior air to enter the house. These structures may also serve as important exit points during emergencies. Without proper maintenance and installation, though, windows may also become sources of cold drafts, increased energy bills and condensation issues.
Homeowners in Canada and elsewhere benefit from energy-efficient windows, wherein the surface interior keeps indoor spaces warmer during extreme frigid weather. This is possible through effectively controlling or reducing moist air, which is the primary cause of window deterioration, while simultaneously improving thermal functions.
