Insulating material element made of mineral fiber felt for clamping-like assembly between beams and the like

摘要

At an insulation material sheet, consisting of a mineral fiber felt bound with a binding agent, of biosoluble mineral fibers, rolled up in the form of a roll, the composition of the mineral fibers features an alkali/earth alkali relation of 1 and the fiber structure is determined by the following features, i.e. average fiber diameter 4 μm, gross density in the range of 8 to 25 kg/m3 and binding agent portion in the range of 4 to 5,5 weight %.
