摘要
The composite panel comprises an insulating core located between two rigid facings (1,2). The core comprises two layers of rigid plastic foam (3A,3B) which are held separated from each other by spacing wedges (4). These wedges delimit several caissons (C1,C2,C3 ..). Low density insulating material (6) is housed in the caissons.
