Basalt Fibre Acoustic and Thermal Insulation
topic
Basalt wool insulation is produced by spinning or flame-blowing basalt melt into discontinuous fibres collected as random fibre mats with binder, providing thermal conductivity of 0.034 to 0.046 watts per metre kelvin, continuous service temperature to 700 degrees Celsius, sound absorption coefficient exceeding 0.9 in the 500 to 4000 hertz range, and non-combustibility classification A1 under EN 13501.
Role
Provides a non-combustible mineral wool insulation with higher service temperature capability than glass wool for industrial pipe and equipment insulation, fire stopping, acoustic partition systems, and building facade insulation where fire safety regulations require A1 non-combustible performance that organic insulation materials cannot achieve.
