Long-term energy efficiency with ArmaFlex® in Jeju Shinhwa World

Located on Jeju island in South Korea, Jeju Shinhwa World is an exciting travel destination that spans a land area of about 2.5 million square metres and cost about US$2.5 billion in development. The project opened progressively from the beginning of 2017 and the second phase of construction has commenced. Jeju is a popular tourist destination and with further plans to position the island as a MICE* capital, Jeju Shinhwa World is at the centre of this development, and expectations - as well as energy demands - on a project of this magnitude is very high.

Insulation of ducting and piping systems is one of the easiest and most cost-effective means of saving energy. Engineers for the project knew that flexible elastomeric foam insulation was the ideal material for HVAC applications, trusting it to provide reliable condensation control and support for long-term energy efficiency. It was also important for them that the material used in this project met with the Korean Standards (KS) - a national standard deliberated by the Industrial Standardization Council in accordance with the Industrial Standardization Law of the country. Armacell’s representatives regularly met with project stakeholders to provide technical advice, including identifying the right insulation thickness for different applications of varying operating conditions. They also proposed the use of complementary accessories, such as ArmaFlex adhesive and tapes to further enhance operational reliability and aesthetics.

A total of 86,000 metres of ArmaFlex Class 1 tube insulation and 26,000 square metres of ArmaFlex Class 1 sheet insulation was supplied to this prestigious project.
