摘要

A heat insulating lifting door is composed of several panels articulated together (4) and which is movable up and down vertical guides at the sides to move the door from an open to a closed position. The articulated areas between the panels (2) are heat insulated along their entire lengths. A heat insulating tube between two neighboring panels (2) is fixed to one of the panels and slides in a circular arched profile formed in or attached to the other panel.
