Energy Efficiency and Insulation
Energy efficiency is a crucial consideration when choosing between steel and fiberglass doors, as it directly impacts heating and cooling costs. Both door types typically feature a foam core insulation that enhances thermal performance, but there are differences in how they handle temperature fluctuations.
Steel doors often have a polyurethane or polystyrene foam core, providing excellent insulation and reducing energy loss. However, steel itself is a good conductor of heat, so if the door’s edges and seams are not properly insulated, thermal bridging can occur, reducing overall efficiency.
Fiberglass doors excel in insulation due to their composite construction, which includes layers of fiberglass and foam core. The fiberglass skin acts as a thermal barrier, and the material’s natural resistance to temperature changes helps maintain indoor comfort more consistently. Additionally, fiberglass doors are less prone to warping or expanding with temperature and humidity shifts, which contributes to their energy-saving properties.
