While metal doors offer high strength, they are heavy and inconvenient to install and use; in contrast, fiberglass doors are 30%–50% lighter yet maintain high strength, resisting deformation and impact while offering greater ease of installation and use.
Metal doors are prone to rusting when exposed to humid, acidic, or alkaline environments over time, whereas fiberglass doors do not rust, making them ideal for coastal, high-humidity, or corrosive settings such as seaside villas and chemical plants.
Metal doors have high thermal conductivity-becoming uncomfortably cold in winter and hot to the touch in summer-and offer poor thermal insulation. Fiberglass doors, however, feature low thermal conductivity, effectively minimizing heat loss to keep interiors warm in winter and cool in summer, thereby promoting energy efficiency and environmental sustainability.
