Ceramic Fiber Blanket
Wet Wool Grade


Ceramic Fiber Blanket Wet Wool (WW) is manufactured for insulating complex shapes, and service under high hot gas velocities. Material is flexible during installation and cures to form a hard rigid structure via air (ambient temperature) or heat in place. Need a custom size? Contact us for a quote.

SKU: N/A Category:


Ceramic Fiber Blanket Wet Wool (WW) is specifically manufactured for insulating complex shapes and services under high hot gas velocities. Material is permeated with inorganic bonding agents and packaged in a clear polyethylene bag to retain the wet binder during shipping and storage. The manufacturing process results in flexible insulation that can be formed to complex shapes in place and air dries to form a hard, rigid structure. Additionally, the material can be cured by immediate exposure to temperature in application. Material has a dry density of 12-18 lbs/ft3 (190-290 kg/m3).
