Exterior doors are more energy-efficient if they are which type?

• A. Solid core
• B. Hollow core
• C. Plywood
• D. Particleboard

Answer: (A)

Solid core exterior doors are considered more energy-efficient because they are constructed with a dense, solid material that provides superior insulation compared to hollow core options. This density helps to minimize the transfer of heat, thereby reducing energy costs associated with heating and cooling the home. Solid core doors typically have a core made from materials like solid wood or composite, which enhances their ability to block thermal energy, leading to better climate control inside the home. In contrast, hollow core doors tend to have an interior cavity that may result in lower thermal resistance. Plywood and particleboard, while widely used in construction, do not offer the same level of insulation as solid core options due to their composition and structure. Therefore, solid core doors are favored for energy efficiency in exterior applications, making them a wise choice for homeowners looking to improve energy conservation.
