Roof - Roof panels are nominally 4½ thick and like the sidewall panels 8 9-1/2 wide x approx. ½ long (or the full depth of the kiln enclosure). These roof panels are fastened to the enclosure with 5/16 stainless steel bolts on 36 centers at each truss and rear beam. The roof and side-wall panels are sealed together using 1/4 x 1-1/2 foam strips, then covered by a formed 0.060 aluminum sealing strip which is fastened to both side-wall and roof panels with stainless steel fasteners on close centers. The roof slope is 1 in 1. Heavy gauge corrugated aluminum sheeting is installed over these roof panels in the field, same as with the side-wall panels
Roof Panel Construction - Roof panels, like the side-wall panels, consist of heavy structural aluminum tube frame welded together and using mineral wool insulation, with a smooth 0.040 aluminum interior and a corrugated 0.032 aluminum exterior, providing the absolute strongest and best sealed kiln enclosure in the industry.
