Insulating curtains are specially designed window treatments that help regulate indoor temperatures by reducing heat loss in winter and blocking heat in summer. Made from thick, layered fabrics, they create a barrier that minimizes drafts and improves energy efficiency in homes. These curtains can also reduce noise from outside, making them a popular choice for urban dwellers. By keeping rooms warmer in cold months and cooler in hot months, insulating curtains can contribute to lower energy bills and a more comfortable living environment.
