The District of Columbia's climate, with its hot, humid summers and cold, damp winters, requires windows that offer robust insulation and excellent sealing. Older homes in D.C. may have original windows that are no longer energy-efficient, leading to significant heat loss in winter and heat gain in summer. Selecting windows with good U-factors and SHGC (Solar Heat Gain Coefficient) ratings is crucial for managing indoor temperatures and reducing utility bills.
