Abstract: A thermal isolator system may comprise a thermal isolator configured to be coupled to an inner wall of a wall system, and a first retainer comprising a first coupling protrusion having a first protrusion shape. The thermal isolator may comprise an isolator body spanning between an isolator outer surface and an isolator inner surface and between an isolator first side and an isolator second side, and a first coupling recess disposed through the isolator outer surface and into the isolator body. The first coupling recess may comprise a recess shape, and the first protrusion shape of the first coupling protrusion may be complementary to the recess shape of the first coupling recess. The first retainer may be configured to be coupled to the thermal isolator by the first coupling protrusion being disposed in the first coupling recess of the thermal isolator.
