Ceramic fiber felt (semi-rigid board) is processed using the wet vacuum forming method. The strength of this type of product lies between that of ceramic fiber blankets and ceramic fiber boards, with a density of around 220 kg/m3. It is suitable for high-temperature applications where flexibility of the product is required. It is commonly used as the backing layer of industrial furnaces, replacing rock wool boards or calcium silicate boards.

Conventional dimensions: 600*400mm or 1200*600mm. Packaging is either in cardboard boxes or on pallets.
