[Asia Economy Reporter Kim Heeyoon] As the government promotes the Green New Deal project and strengthens insulation regulations, attention is focusing on the performance of high-performance low-emissivity (Low-E) glass, an essential material.

According to industry sources on the 24th, as part of the government's Green New Deal project, a green remodeling project is underway for public buildings (such as daycare centers, health centers, and medical institutions) that have been in use for more than 15 years, increasing demand for high-performance windows that prevent energy loss.

This project is being promoted to respond to climate change by remodeling public buildings to enhance energy efficiency and reduce greenhouse gas emissions. A total of 841 projects are scheduled to be carried out this year. The main components include replacing high-performance windows, reinforcing insulation materials, and installing renewable energy systems or high-efficiency heating and cooling equipment.

Experts point out that since windows account for the largest portion of energy loss in buildings, replacing them with high-performance windows is important. Glass occupies the largest area in windows, so applying high-performance glass to improve the insulation performance of the glass and reduce energy loss is effective.

Low-E glass performance varies significantly depending on the number of silver coating layers. There are various types of Low-E glass, from the commonly used transparent single Low-E glass in apartments to double or triple Low-E glass applied in high-rise buildings or government offices. Single Low-E and double/triple Low-E glass show insulation performance differences of over 50%.

Glass specialist company Hanglas continues to develop high-performance coated glass products ranging from single Low-E to triple Low-E. Since the first launch of double Low-E glass in 2007, it has recorded a cumulative domestic sales volume of 6.5 million square meters over 15 years. It holds about an 80% market share in the double Low-E market.

In particular, the double Low-E product ‘SKN154II,’ launched in 2011, maximizes insulation effects and excels in energy savings, being applied in many schools, government offices, and large high-rise buildings. Numerous window tests conducted over 10 years with SKN154II have verified that Hanglas’s double Low-E glass not only has excellent insulation performance but also reliable coating quality, superior processability, and durability.

A Hanglas representative explained, "When installing high-performance windows with energy efficiency ratings of 1 to 2 grades applied in public green remodeling, glass of double Low-E grade or higher is used. However, in the past, there were issues where glass products different from those in the test reports were delivered in some government projects, causing rework. Therefore, it is important to verify that the glass delivered on-site is installed with the same specifications as the window test reports."

Hanglas began producing flat glass domestically for the first time in Korea in 1957 and has led the domestic glass industry. It has established the largest coated glass processing plant in Korea and has developed and introduced various solutions to save energy and protect the environment in buildings, such as high-performance coated glass and smart glass.
