A flame resistant insulation product comprises a fibrous mineral material that has been rotary fiberized, preferably a fibrous glass. The composition of the mineral material has a softening point of at least about 699°C (1290°F). An insulated duct includes a tubular wall that defines a hollow interior for conducting a fluid, and a layer of the insulation product wrapped about the wall. The mineral material reduces the number of samples of the insulated duct failing the flame penetration test of a UL 181 Standard compared to the same insulated duct with a mineral material having a softening point of less than 699°C (1290°F).
La présente invention concerne un produit d'isolation ininflammable comprenant un matériau minéral fibreux qui a été obtenu par fibérisation rotative, de préférence un verre fibreux. La composition du matériau minéral présente un point de ramollissement d'au moins environ 699 DEG C (1290 DEG F). L'invention concerne également un conduit isolé comprenant une paroi tubulaire définissant un intérieur creux de conduite de fluide, et une couche de produit d'isolation enroulé autour de la paroi. Le matériau minéral réduit le nombre d'échantillon de conduit isolé échouant au test de pénétration au feu selon UL181 par rapport au même conduit isolé avec un matériau minéral dont le point de ramollissement est inférieur à 699 DEG C (1290 DEG F).
