New safety regulations imposed by Ministry of Manpower (MOM) for engineers in Singapore. 
Industrial insulation is designed to control heat transfer, improve energy efficiency, protect personnel, and support stable operating conditions. However, the insulation material cannot perform effectively for long if it is left exposed to rain, sunlight, chemicals, or physical impact.
Moisture can enter damaged or poorly sealed insulation, while ultraviolet exposure can degrade certain facings and coverings. Routine maintenance, foot traffic, tools, and nearby operations may also tear or compress the insulation.
Weatherproof jacketing provides the external protection needed to help the complete insulation system remain effective throughout its intended service life.
