Ceramic Fiber Blanket
Category: Ceramic Fibers
Overview
Ceramic fiber blanket is a needled refractory insulation product manufactured from spun alumino-silicate ceramic fibers. The needling process interlocks the fibers to produce a flexible, resilient blanket that maintains dimensional stability at high temperatures. It provides significant energy savings over refractory brick due to its low heat storage capacity.
