Le document FR-2 792 349 concerne un isolant thermique et phonique constitué de deux films à bulles, dont la face externe est recouverte par une couche extérieure comportant de l'aluminium. Une couche de mousse, de préférence de polyéthylène, est interposée entre les deux films à bulles. Des lignes de soudure thermique latérales et en zone médiane solidarisent les films à bulles et la couche de mousse intermédiaire. La couche de mousse intermédiaire est soudée entre les deux films, ce qui permet la présence de lames d'air isolées les unes des autres.FR-2 792 349 relates to a thermal and acoustic insulation consisting of two bubble films, the outer face is covered by an outer layer comprising aluminum. A layer of foam, preferably polyethylene, is interposed between the two bubble films. Side and medial thermal welding lines solidify the bubble films and the intermediate foam layer.

Le document US-4 038 447 présente différents modes de réalisation de complexes isolants, et notamment un complexe isolant comprenant principalement deux films en plastique ou en matériau résistant au feu, lesquels films plastiques prennent en sandwich une couche ignifugée, telle qu'une mousse flexible de polystyrène associée à un additif tel que du triphosphate, de l'hexabromocyclododécane ou tout autre produit similaire. Les bordures des deux films en plastique entourant la couche intermédiaire ignifugée sont cousues ou soudées l'une à l'autre, de manière à permettre une circulation de l'air présent au sein du complexe avec l'extérieur, et permettre la sortie de l'humidité éventuellemenf présente entre les deux films.US-4,038,447 discloses various embodiments of insulating complexes, and in particular an insulating complex comprising mainly two films of plastic or fire-resistant material, which plastic films sandwich a fireproof layer, such as a flexible foam of polystyrene associated with an additive such as triphosphate, hexabromocyclododecane or any other similar product. The edges of the two plastic films surrounding the fire-resistant intermediate layer are sewn or welded to each other, so as to allow the circulation of the air present in the complex with the outside, and allow the exit of the moisture present between the two films.
La présente invention propose un perfectionnement à ces matériaux pour améliorer ses propriétés d'isolation thermique notamment, sans nuire à ses propriétés classiques qui découlent de sa faible épaisseur et surtout de sa très grande facilité de manipulation.The present invention provides an improvement to these materials to improve its thermal insulation properties in particular, without harming its classic properties that result from its small thickness and especially its very easy handling.
Le complexe isolant selon l'invention comprend une feuille en polystyrène mince, placée librement entre les feuilles à alvéoles d'air dont les bordures latérales sont soudées sur toute leur longueur, lesquelles feuilles à alvéoles sont recouvertes extérieurement par collage ou thermosoudure d'un revêtement en forme de film d'aluminium.The insulating complex according to the invention comprises a sheet of thin polystyrene, placed freely between the air-cell sheets whose lateral edges are welded over their entire length, which cellular sheets are covered externally by bonding or heat-sealing a coating in the form of aluminum film.

De préférence, l'épaisseur de cette feuille de polystyrène est de l'ordre de 2 mm de façon à conserver une grande souplesse pour le complexe.According to the invention, the polystyrene sheet has a thickness of the order of 2 to 10 mm.

Un procédé particulier de fabrication de ce complexe isolant consiste - à solidariser un film d'aluminium sur l'une des faces d'une feuille à alvéoles d'air, par collage ou thermosoudage, - à disposer deux feuilles à alvéoles d'air recouvertes du film d'aluminium extérieur de part et d'autre d'au moins une feuille en polystyrène expansé, et - à souder les bordures latérales des feuilles à alvéoles d'air de sorte à laisser libre la feuille en polystyrène expansé.A particular method of manufacturing this insulating complex consists in: - bonding an aluminum film on one of the faces of an air-cell sheet, by gluing or heat-sealing, - arranging two sheets with air cells covered outer aluminum film on either side of at least one sheet of expanded polystyrene, and - to weld the side edges of the air-cell sheets so as to leave the expanded polystyrene sheet free.
Toujours selon l'invention, l'étape de soudure des bordures latérales des feuilles à alvéoles d'air est réalisée par une barre de soudure à chaud, le pas d'avancement de l'ensemble feuille en polystyrène expansé et feuille à alvéoles d'air étant égal ou sensiblement égal à la moitié de la longueur de la capacité de chauffage de la barre de soudure à chaud, ce qui permet une double pression de chauffage sur toute la longueur de la bordure latérale des feuilles à alvéoles d'air.Still according to the invention, the step of welding the lateral edges of the air-cell sheets is carried out by a heat-sealing bar, the advancing step of the expanded polystyrene foil assembly and the foil-shaped foil. air being equal to or substantially equal to half the length of the heating capacity of the heat seal bar, which allows a double heating pressure along the entire length of the side edge of the air-cell sheets.
