Abstract
The purpose of the disclosure is to provide an insulation structure for efficiently controlling a thermal flow and protecting objects that is easy to implement, has a low cost and is compliant with strict standards in terms of fire resistance while offering protection against crushing and immersion. Accordingly the disclosure relates to a method for protecting at least one object previously encapsulated in a sealed pocket, that comprises imbedding the objects without trapping any air in a body of a high thermal-resistance insulator containing gypsum crystals, said insulator body being cast in a structure having a high mechanical resistance to crushing, and said structure consisting of an intermediate mould or directly defining a housing. A casing obtained by said method comprises the body block of a high thermal-resistance insulator and the housing having a high mechanical resistance to crushing. Advantageously, the objects, such as an electronic board, are encapsulated in a silicone sealed pocket, and the housing includes steam discharge slots as well as an opening for casting the insulator body, said opening being then closed by a plate held on the housing by screws. Sealed ducts…
