Fiberfrax® Acoustic Blankets are lightweight, needled insulating blankets manufactured from Fiberfrax refractory ceramic fibres, and are specifically engineered to provide superior acoustic properties. These blankets are entirely free from binders, display excellent chemical resistance and do not cause corrosion in metal structures. The long, interlocking spun fibres ensure excellent handling strength and resistance to vibration. During the manufacturing process, various fibre properties are controlled to optimise the sound attenuation properties of the blanket.
