Do insulated curtains work to improve energy efficiency? Yes, insulated curtains are designed with thermal linings or multi-layered fabrics that reduce heat loss during winter and block heat in summer. By enhancing window insulation, these curtains help maintain consistent indoor temperatures and lower energy costs. Their effectiveness depends on fabric quality, fit, and installation, making them a practical addition for energy-conscious households.
