Engineered for low thermal transmittance, structural integrity, and contemporary minimalist aesthetics across Daejeon's diverse architectural landscape.
Addressing the rigorous building codes and distinct climate requirements of South Korea's Central Innovation Hub
Situated in the interior basin of South Korea, Daejeon experiences extreme seasonal temperature swings ranging from sub-zero winters (-15°C) to intense, humid summers (+35°C). Structural window systems must maintain low thermal transmittance (U-factors ≤ 1.2 W/m²K) to satisfy Korea Energy Code standards (KS F 2292) and combat indoor condensation during freezing spells.
Home to Daedeok Innopolis, Yuseong-gu tech corridors, and major government complexes, Daejeon leads in sustainable green building design. Commercial and institutional architecture demands structural fixed aluminum picture windows with exceptional airtightness, sound insulation (STC ≥ 40 dB), and high solar heat gain control (SHGC) to reduce building HVAC energy consumption.
As a key exporter serving the Daejeon metropolitan region, Shandong Envi Doors and Windows Co., Ltd. custom-engineers fixed aluminum window profiles that seamlessly comply with South Korean National Construction Standards. Our fixed aluminum glazing systems incorporate Multi-Chambered Polyamide Thermal Breaks (PA66 GF25), structural silicone glazing (SSG), and specialized Low-E argon-filled triple insulating glass (IGU) designed to withstand high structural wind pressure loads prevalent during the East Asian monsoon season.
By replacing legacy steel or non-thermally broken frames, our architectural fixed picture windows maximize indoor daylighting efficiency while guaranteeing optimal energy conservation for commercial towers, research centers, luxury residential villas, and civic infrastructures across Yuseong-gu, Seo-gu, and Jung-gu districts.
Advanced aluminum extrusion, surface treatment, and thermal barrier technologies tailored for high-performance envelopes
Utilizing high-precision Technoform polyamide insulating bars (PA66 GF25), our fixed aluminum frames eliminate thermal bridges. This results in minimal heat transfer between exterior and interior envelope zones, fulfilling Korea’s Zero Energy Building (ZEB) criteria.
Equipped with vertical anodizing and electrophoretic coating lines, as well as 1,000-ton color powder spraying units, our profile finishes offer superior resistance to atmospheric corrosion, salt spray, UV degradation, and localized industrial pollutants.
Our fixed windows feature customized double and triple-glazed tempered glass units with soft-coat Low-E layers, warm-edge spacers, and 90%+ Argon gas fill, achieving extreme sound insulation (up to 45 dB reduction) and optimal acoustic control.

Over 30 years of metallurgy excellence, industrial scale extrusion, and worldwide export leadership
Founded in 1993, Shandong Envi Doors and Windows Co., Ltd. (established as a dedicated door & window corporate unit in 2014) has grown into a premier global enterprise integrating aluminum profile design, precision extrusion, surface treatment, and window fabrication. Spanning an expansive manufacturing facility of 100,000 square meters, our plant houses automated extrusion presses ranging from 600 tons to 2,500 tons capacity.
With an annual extrusion design capacity of 50,000 tons and an annual output value exceeding 1 billion RMB (~140 Million USD), we maintain total quality control over every production phase—from raw aluminum billet melting to final CNC milling, corner welding, seal strip fitting, and structural glass insertion.
Exporting to 100+ countries with custom engineering for Korean market standards.
Tailored aluminum glazing systems engineered for specialized building typologies in Daejeon’s urban center
In research institutes and semiconductor innovation laboratories, fixed aluminum windows provide massive uninterrupted floor-to-ceiling glass facades. High acoustic dampening seals internal acoustic privacy while high light-transmittance glass boosts natural illumination.
For high-density luxury apartments and mixed-use complexes, fixed picture window combination units deliver ultra-slim sightlines, maximum structural stability under typhoon wind loads, and thermal insulation that drastically lowers winter heating costs.
Serving universities, cleanrooms, and municipal headquarters in Daejeon, our heavy-duty aluminum fixed window systems incorporate tempered laminated safety glass and powder coatings that withstand high ambient foot traffic and environmental exposure.
Customizable options available for Daejeon importers, general contractors, developers, and facade fabricators
Innovating next-generation sustainable curtain walls, smart glass integrations, and carbon-neutral fenestration
As South Korea accelerates its 2050 Carbon Neutrality Initiative, Daejeon's futuristic developments are moving toward Building-Integrated Photovoltaics (BIPV) and dynamic electrochromic glass. Our fixed aluminum window extrusions are specifically engineered with internal wire channels and reinforced structural pockets to accommodate solar-active glass panels and automated tinting controls seamlessly.
Modern Korean architectural trends favor high visual connectivity between indoor workspaces and natural surroundings. Our engineering team is advancing ultra-concealed aluminum frames with sightlines under 35mm that withstand heavy dead-loads of structural triple glazing while maintaining superior structural rigidity.
Everything Daejeon architects, developers, and procurement managers need to know
Our fixed windows feature multi-chambered polyamide thermal breaks (PA66 GF25) paired with Low-E triple glazing or double glazing filled with 90%+ Argon gas. This allows our configurations to reach overall U-values down to 0.8–1.2 W/m²K, easily surpassing the energy efficiency thresholds set by South Korea’s Ministry of Land, Infrastructure and Transport for the Central Zone (Daejeon area).
We recommend our architectural-grade fluorocarbon (PVDF) spray coating or high-durability AkzoNobel powder coatings. These finishes conform to AAMA 2605 specifications, guaranteeing resistance against color fading, chemical erosion, and moisture retention through Daejeon's hot summers and freezing winters.
We ship directly from our Shandong production base via major ocean ports such as Qingdao or Weihai to Busan Port or Incheon Port in South Korea. Sea transit typically takes 2 to 4 days, followed by rapid customs clearance and inland trucking directly to construction sites in Daejeon within 7 to 10 days post-fabrication.
Yes. Shandong Envi offers custom extrusion dies and engineering support. We manufacture large-span structural fixed picture windows up to 3,500mm x 2,400mm single-pane dimensions, supported by internal steel or aluminum structural stiffeners to withstand wind pressures up to 5,000 Pa.
Our factory operates under ISO 9001 and ISO 14001 certification. Every batch of 6063-T6 aluminum alloys undergoes cross-sectional spectrometry, tensile testing, coating thickness analysis (minimum 40-80 microns for powder coating), and water tightness testing (KS F 2292) before final packaging.
