发明名称 Sectional door panel
摘要 A panel for use in a sectional door. The panel which is easy to construct and has improved insulating properties, has an elongated insulating core, a first metallic skin on one face of the core and a second metallic skin on the other face of the core. The first and second metallic skins both have crimped edges that are joined together at the sides of the panel with an insulating member interposed between them. The insulating members on the long sides of the panel may include diverging seal arms projecting outwards for providing a seal between adjacent panels. The invention is also directed toward a sectional door incorporating the panels.
