The external sliding thermal insulation structure is composed of working steel pipe, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening steel strip, sliding guide bracket, air insulation layer, external steel pipe and external anti-corrosion layer. 5. Outside the insulation layer. Put on the insulation layer. It can also be insulated and cooled, and it can also be used as the maintenance layer of black waterproof layer, moisture-proof outer wall, and so on. ?
