Why sandwich Garage Doors Offer Better Insulation and Energy Efficiency

The reason electric garage doors can provide better thermal insulation and energy-saving effects lies in their advanced materials and structural design. The multi-layer composite door panels are filled with high-density polyurethane foam, forming an efficient thermal insulation layer that significantly reduces heat exchange between the indoor and outdoor environments. This helps block high temperatures from intruding in summer and prevents heat loss in winter, thereby lowering energy consumption for air conditioning and heating.

The door edges are equipped with weather-resistant sealing strips that fit snugly against the door frame, eliminating air leakage of cold or hot air. Some high-end models also incorporate low-emissivity coated glass or reflective coatings to further reflect solar radiation heat. These integrated design features work together to maintain a more stable temperature inside the garage, reduce energy waste, and substantially lower household energy costs over the long term.
