Removable covers offer flexibility for insulating spaces around movable components that might otherwise go un-insulated. They allow for heat retention while still allowing the valve, steam trap, etc. to be serviced and inspected as necessary.
Removable insulators are also well-suited for replacing asbestos mats, millboard and refractory paper. Materials for today’s removable insulation covers include 100% fiberglass, or ceramic fiber and silicone coated cloth.
