Fiberfrax® Castables are insulation materials composed of Fiberfrax refractory ceramic fibres blended with hydraulic setting binders. Water is added to these dry mixes (on site) and mixed to produce a cement-like consistency, which upon setting produces a strong, rigid, insulating shape. These versatile products are designed for casting or ramming applications such as casting shapes, coatings, linings and general refractory repairs.
