[Asia Economy Reporter Kim Heeyoon] Hanglas announced on the 11th that it has launched the triple low-emissivity glass 'XTN145II,' manufactured using purely domestic new technology.

According to Hanglas, triple low-emissivity glass refers to glass coated with three layers of silver (Ag) film. The triple low-emissivity glass developed by Hanglas utilizes a new coating technology based on a special nano process, achieving world-class thermal insulation performance while also providing optical properties such as color, the company added.

This product, when applied to metal window frames mainly used in buildings, can achieve a window heat transfer coefficient of less than 1.2 W/m2K with just double glazing, thereby meeting the upcoming strengthened window energy consumption efficiency Grade 2 standards. Additionally, when applied to public buildings, it offers optimal conditions and aesthetically features a 25% lower reflectance and a neutral color, making it suitable for architectural trends, according to Hanglas.

Furthermore, this product has a domestic lowest-level solar heat gain coefficient (SHGC) performance of 0.2, effectively blocking solar heat entering indoors from outside. This advantage significantly reduces cooling loads, which is a major issue for commercial buildings.

Hanglas emphasized that as energy savings for commercial buildings are gradually strengthened, XTN145II provides an optimal solution for zero-energy buildings by reducing heating loads based on thermal insulation performance as well as reducing cooling loads with its low solar heat gain coefficient (SHGC).

A Hanglas official stated, "Existing imported triple low-emissivity glass products are excessively expensive relative to their performance and have recently struggled to meet the strengthened domestic insulation standards. The newly developed XTN applies a special nano process, offering superior thermal insulation and solar heat gain coefficient performance tailored to domestic standards, making it an evolved triple low-emissivity glass compared to existing foreign products."

Meanwhile, Hanglas announced that it is currently applying for a patent on the new technology applied to XTN145II. The company also added that it plans to expand its excellent product lineup based on this new technology in the future.
