What is the most energy-efficient front door?

 The most energy-efficient front doors are typically made from aluminum. Aluminum doors excel in energy efficiency due to their ability to incorporate thermal breaks, which minimize heat transfer and help maintain indoor temperatures. They are lightweight, durable, and resistant to weather damage, making them a long-lasting and environmentally friendly choice.

Other energy-efficient materials include fiberglass and steel. Fiberglass doors are designed with insulating cores that reduce energy loss, while steel doors often include foam cores for superior insulation. However, aluminum remains a preferred option for modern homes because it combines high energy efficiency with sleek, contemporary designs.
