ABSTRACT:
An energy efficient garage door construction comprising a plurality of interconnected door sections. Each of the sections includes a pair of symmetrical metal panels forming the opposed sides and long edges of the section, an expanded polystyrene core to which the metal panels are adhesively bonded, and a pair of generally U-shaped end pieces nestingly received between the metal panels. The metal panels form oppositely facing recesses along one side edge and tongues along the other side edge so that adjacent panels interfit to create a baffle effect, and the panels are held together by C-shaped retaining plates which serve the secondary function of hinge reinforcement members.
