摘要
An element essentially consisting of mineral wool exhibits an enhanced reaction to fire. Such an element is especially in the form of a panel and is used for the construction of air ducts. The panels comprise a glass wool core, said core being formed from glass fibers which act as components of the wool. The glass fibers of the element according to the invention have a diameter substantially greater than the diameter of the glass fibers which are presently used for the manufacture of panels or of ducts for similar applications. The glass fibers used according to the invention have a fineness index with a value which fluctuates between 5.8±0.5 for 6 grams. The invention also relates to a process for manufacturing an air duct from said panels.
