Abstract

La présente invention concerne un isolant thermique ayant un caractère ignifugeant. Une couche d'air interne (12) est formée par liaison de films de surface supérieur et inférieur (16, 18) constitués d'aluminium sur les côtés supérieur et inférieur d'un isolant thermique de volume multicouche (14) divisé par un film interne (20) ayant une faible émissivité ; comme l'isolant thermique de volume multicouche (14), une mousse de polyéthylène, une mousse de polypropylène, une mousse de mélamine, une mousse d'acétate de vinyle d'éthylène, une mousse d'uréthane, une mousse de caoutchouc ou analogue, dans laquelle un produit ignifuge est distribué, étant sélectivement utilisée de telle sorte que l'isolant thermique de volume multicouche (14) a un caractère ignifugeant. En particulier, le film de surface supérieur (16), qui est exposé à l'extérieur pendant la construction et est soumis à une forte chaleur en cas d'incendie, est formé d'un matériau unique ou de multiples matériaux choisis parmi une feuille d'aluminium épaisse, un film composite d'aluminium, une feuille composite d'aluminium et un feutre composite d'aluminium comme couche unique ou multiples couches, de façon à satisfaire non seulement l'isolation thermique requise pour un isolant thermique pour la construction, mais également le caractère ignifugeant pour la sécurité incendie d'un bâtiment même avec une structure simple et une épaisseur minimale.
