Abstract
A free standing thermal enclosure for use as part of an oven, furnace or refrigeration system, including a plurality of adjoining insulating walls and a ceiling spaced inwardly from and supported by an open skeletal framework. The walls and ceiling are formed by interlocking, non-structural pads of a pliant, low density, insulating material that can be made of interlaced ceramic fibers.

A free standing, thermal enclosure comprising:
- a substantially rigid skeletal framework defining a substantially rectangular three-dimensional space, said framework including a centrally disposed, horizontal ridge pole and a plurality of inclined buttress members;
- a plurality of adjacent solid walls and a ceiling disposed within said framework and spaced inwardly therefrom, said walls and ceiling being formed by interlocking non-structural pads consisting of a pliant low density insulating material made of ceramic fibers, the sides of said pads being exposed and substantially free of contiguous supporting structure along the interior and exterior surfaces of said walls and ceiling, said pads having elongated vertical openings therein;
- a plurality of hangers extending inwardly from said framework and inserted between said pads;
- and
- a plurality of rods inserted in said openings, said rods being engaged by said hangers.
