[Asia Economy Reporter Kim Jong-hwa] Window frames play a crucial role in maintaining a consistent temperature around windows and doors, preventing excessive heat loss or absorption, and are key contributors to reducing heating and cooling costs. They are also essential materials to consider first when building a new apartment or remodeling a home.
As the rainy season ends and the heatwave continues day after day, the battle for high-performance window frames is heating up. LX Hausys Z:IN window frames' 'Super Save Series,' KCC's 'Klenze,' and Igeon Window's 'Passive Series' are fiercely competing in the housing market, which is mired in recession.
LX Z:IN window frames' 'Super Save Series' simplifies the previously complex window products into numbers 3, 5, and 7 according to function and price range for easier customer understanding. The LX Z:IN Super Save 3, 5, and 7 meet the highest grade specifications in basic window performance, including energy consumption efficiency grade 1 for double-glazed windows, airtightness grade 1, and water tightness grade 50. Additionally, high-functionality accessories with design elements such as antibacterial handles that enhance hygiene, window sash stoppers that prevent damage or deformation during opening and closing, and insect screen locking devices have been applied to further improve customer convenience.
'Super Save 7' minimizes the exposure of white PVC frames, uses a glass fixing method with rubber packing similar to system windows, and features an alarm handle with LED lighting and sound to indicate the opening and closing status. 'Super Save 5' and 'Super Save 3' apply insect drainage caps on the window frame drainage holes to prevent pests from entering indoors, resolving customer inconveniences.
Notably, the Super Save Series has received positive reviews from consumers by being sold through B2C (business-to-consumer) channels, directly receiving consumer choices. Since its first launch in 2015, the Super Save Series has established itself as a leading domestic high-insulation window brand, including being selected as the '2022 Korea Green Product of the Year' by the Korea Green Purchasing Network (KGPN) last month.
KCC's 'Klenze' borrows its name from the famous 19th-century German architect Leo von Klenze. It pursues a premium brand that presents the dignity of windows through the completion of light and space. Klenze is a high-end window brand that differentiates itself from existing premium windows with the motto of ▲restraint rather than ostentation ▲details that are not visible rather than styles that stand out ▲lasting atmosphere rather than temporary stimulation ▲quietly strong aura rather than flashy display.
It reflects a stable sense of proportion and the beauty of symmetry in its design, embodying Klenze's architectural philosophy, who was an architect that meticulously explored light and space. It incorporates high technology and dignity into windows, one of the most important elements that connect and complete the inside and outside of residential spaces. Based on top-tier technology and quality, it offers excellent insulation performance while securing spacious interiors and external views. It also features safety and luxurious design through a composite material of aluminum caps and PVC.
Klenze targets the high-end premium window market, including reconstruction, redevelopment, and luxury new complexes. Developments such as The H Xi Gaepo, The H La Class (Seocho), The H Forecent (Gaepo), The H Firstier I-Park (Gaepo), Godeok Arteon, Susaek DMC Fine City Xi, Dunchon Olympic Park Foreon, Suwon Hillstate Prugio, Gwacheon Centreville, Ilsan The Sharp Gravista, Godeok Gracium (Gangdong), and Helio City (Songpa) have chosen Klenze.
Igeon Window's Passive Series 'ESS 250 LS' is a premium lift-sliding system window in the 'Passive Series' that enhances energy efficiency through revolutionary insulation performance improvements, featuring high insulation and airtightness. Through double-bridge insulation design, it achieves insulation performance equivalent to double-glazed windows despite being a single window. Especially when combined with Igeon's SUPER vacuum glass, it realizes an astonishing insulation performance with a thermal transmittance rating of grade 1 (0.87W/㎡K).
From a design perspective, the slim frame integrates the fixed frame of the window with the window frame, adding a touch of luxury. This allows the interior to be brighter and more radiant, and the expanded glass area is designed to let residents fully enjoy the beautiful external scenery indoors.
Nine One Hannam, the country's most luxurious complex, has chosen the 'ESS 250 LS.' Among the top 10 publicly announced apartment prices released by the Ministry of Land, Infrastructure and Transport last March, seven sites use Igeon Window's products, showing strength in the luxury housing and apartment market.
An industry insider said, "Replacing only the window frames in an old house can reduce annual heating and cooling costs by 40%," adding, "Windows released these days must have safe performance that withstands heatwaves and cold waves and excellent view securing. The quality has been leveled up so much that there is no need to distinguish between premium and standard."
