Thermal Insulation
Thermal insulation is material applied to hot or cold equipment to slow heat transfer. On industrial hot surfaces it reduces energy loss, stabilises process temperatures and protects workers. Removable insulation lets fittings be re-accessed for maintenance without destroying the insulation.
Insulation works by trapping low-conductivity material (mineral wool, silica, aerogel) around a hot surface so that heat must cross a high-resistance layer before reaching the air. Traditional rigid cladding has to be cut off to inspect a valve and rebuilt afterwards, so it is often left off complex fittings. Modular removable insulation keeps those fittings covered while still allowing fast maintenance access.
