Industry & Occupation
Classification
Summary
Thermal insulation work (lagging worker) is a specialized technical occupation that installs insulation and heat-retaining materials on pipes and equipment to prevent heat loss and condensation.
Description
Lagging workers (thermal insulation work) process and install insulation and heat-retaining materials on equipment such as boilers, pipes, ducts, and tanks to suppress heat loss, prevent condensation, and ensure a safe working environment. On-site, they handle tasks from dimension measurement to material cutting, forming, and installation using fixing hardware and adhesives. They work at indoor and outdoor sites, often in high places or confined spaces, requiring safety and health management as well as proper operation of tools and equipment. It is essential to understand the properties of various materials (glass wool, rock wool, aluminum foil, foamed urethane, etc.) and select the optimal construction methods.
Future Outlook
From the perspective of energy conservation and environmental considerations, demand for insulation technology is stable or expanding. As high-efficiency insulation materials and advanced construction techniques progress, increasing expertise will enhance market value.
