Abstract
An industrial furnace with insulating walls comprising side-by-side pre-formed panels each including a plurality of ceramic insulating modules. The side wall panels include vertical buckstays to which the modules are secured by retainer clips including sharp spikes inserted into side edge surfaces of the insulating modules. Modules with offset stepped side profiles are disclosed, arranged to provide for ready removal of a single module without disturbing adjacent modules. Atmosphere furnace insulation arrangements also are disclosed utilizing ceramic modules secured to the furnace shell by special retainer clips embedded in side edge surfaces of the modules.

An industrial furnace used for material heat treatment and the like, comprising:
- a plurality of sets of ceramic fiber insulating modules with each set arranged in a vertical stack and disposed to present contiguous aligned surfaces to the furnace interior;
- support means comprising rigid elements supporting each of said modules vertically;
- a plurality of retainer clip means for said modules;
- each of said retainer clip means including at least one sharp spike inserted into the side edge surface of a corresponding module;
- each of said retainer clip means further including at least one spike support arm extending horizontally from the corresponding spike to the outer surface of the module, remote from the furnace interior;
- and
- means interengaging said spike support arms and said rigid elements to provide for holding the modules securely against horizontal movement.
