Shop here for all of your kiln insulation needs -- various thicknesses of ceramic insulation fiber, paper, kiln blankets, and more!

Ceramic insulation fiber is a popular flexible ceramic refractory material that looks like soft, puffy cotton -- but be careful, because it certainly doesn’t have that cottony feel! In fact, we recommend not touching it at all unless you are wearing gloves and not tearing or cutting it unless you are wearing a respirator. Ceramic insulation fiber is an essential element in kiln-building and kiln ‘buttoning’. This lightweight, blanket-like material will keep heat in without catching on fire, and its fibrous texture makes it great for filling in small draft holes and helping to slow down your kiln’s cooling.

Similar to ceramic insulation fiber in material is ceramic insulation paper. Yes, this is a flat, paper-like version of refractory ceramic insulation fiber, and is great for living kiln shelves and is a very popular product with glass artists. If you slump or fuse glass, ceramic insulation paper is a great product to have on hand.

We can cut any fiber blanket or paper product to your size specifications.  Sold by the foot unless otherwise noted.
