Removable Insulation
Removable insulation is a reusable, fitted insulation jacket that wraps hot or cold equipment - valves, flanges, steam traps, pumps, turbines - and can be unfastened for maintenance and refitted without damage. Unlike permanent rigid lagging it lets technicians access the equipment in minutes and reuse the same jacket for years.
Removable insulation consists of an inner insulating layer (mineral wool, silica or aerogel) inside a durable outer fabric, closed with straps, hooks or quick-release fasteners. It is purpose-made to the geometry of irregular components that are impractical to lag permanently - valves, flanges, heat exchangers, expansion joints - where rigid insulation would have to be cut away every time the equipment is serviced.
The business case is twofold: it cuts heat loss from otherwise-bare hot surfaces (reducing fuel use and CO2), and it slashes maintenance time because covers come off and back on in minutes instead of being demolished and rebuilt. Well-designed jackets also hold the outer surface temperature to a safe level for personnel and can be specified for service temperatures up to several hundred degrees C.
