Definition
Windows are transparent openings providing light, ventilation, and views while maintaining weather resistance and thermal performance. Efficient windows include Low-E coatings and insulated frames. Proper installation prevents water intrusion.

Windows are specified by size, frame material (wood, vinyl, aluminum, fiberglass), glass type (single, dual, triple pane), and performance ratings. Energy-efficient windows include low-emissivity (Low-E) coatings and insulated frames. Window placement impacts heating, cooling, and daylighting. U-factor and Solar Heat Gain Coefficient (SHGC) measure thermal performance. Proper installation with flashing is critical to prevent water intrusion.
Pro Tip
Window quality dramatically affects heating/cooling costs and comfort. Invest in energy-efficient windows, especially in extreme climates.
Example
A climate-efficient home uses triple-pane, Low-E windows with fiberglass frames and SHGC rating of 0.23 to minimize solar heat gain in summer.
