Mat made of inorganic fibres which have a random or quasi-random orientation and which have diameters which in the case of the large majority thereof, are from 2.5 to 4.5 micrometers, and a length of 2 to 15 cm. It has the following characteristics: its density, lower than 40 kg/m<3> is particularly low, its compressive strength, in the case of a crushing of 10%, is equal to at least 0.5 kN/m<2>. The fineness of the fibres and their random distribution endow the mat with an exceptional lightness and an excellent flexibility permitting, inter alia, the perfect application of the mat to cylindrical surfaces. |
