Abstract:
1. A process for producing, in an interspace ( 101 ; 703 ) of a device, an insulating protection system formed of at least a vacuum insulating panel ( 20 ; 30 ) submerged in a matrix of homogeneous polymeric foam ( 602 ; 707 ), comprising the steps of introducing the panel into the interspace defined by first and second opposing walls ( 103 , 104 ) while leaving a free internal space between the panel and at least one of the walls, heating the interspace at a temperature of at least 100° C. by a heat source located outside the interspace, filling the free internal space between the walls of the interspace with fluid polymeric foam, cooling and solidifying the foam, wherein the following steps are carried out before heating the interspace at temperature of at least 100° C.: providing a flexible protection system of cardboard ( introducing the protection system into the interspace in such a way that the protection system is placed at least in a portion of the interspace between the first wall (
