        "text": "When choosing energy-efficient windows, look for several key features. Double or triple-pane glass with argon or krypton gas fills provides excellent insulation. Low-emissivity (low-e) coatings on the glass help reflect heat, keeping your home cooler in summer and warmer in winter. The U-factor, which measures heat transfer, should be low, typically 0.30 or less. Also, check the Solar Heat Gain Coefficient (SHGC) for how well the window blocks heat from the sun; a lower SHGC is better for preventing overheating in sunny climates. Look for durable frame materials like vinyl, fiberglass, or wood-clad, and quality weatherstripping to prevent air leaks.",
