Abstract: An insulating block for lining an interior surface of a furnace wall. The block is comprised of at least two insulating module sections. Each module section is formed from two or more layers of a ceramic (material) blanket. The layers of the ceramic blanket are held together by one or more plastic fasteners, each plastic fastener comprised of an elongated fiber portion that is dimensioned to extend at least partially through at least two of the layers and enlarged end sections dimensioned to engage the layers. The layers of the blanket are held together side-by-side by the plastic fasteners. A support member has at least one anchor rod (tube) affixed thereto. The insulating module sections are mounted on the anchor rod.
