摘要

The frame has a leaf case (100a) to receive a surface element (101a), and another leaf case to receive another surface element. An upper frame section (3a), lower frame section (3b) and lateral frame sections are made of composite material. Each section has plastic insulating bars (6) placed between an interior shell (4) and an exterior metal shell (5). The lower section has mobile rails (8a, 8b) with guiding grooves (9a, 9b) to guide one of the cases. A plastic adjustment piece (10) is inserted in a zone between the parallel rails for thermal insulation of the shells of the lower section.
