Factory Expertise & Engineering
Leading OEM Custom Aluminum Fixed Window Manufacturing
For over 15 years, KARON (Karon Window & Door Co., Ltd.) has operated as a benchmark manufacturer based in Foshan, China—the global epicenter of architectural aluminum profile extrusion.
Technical Metallurgy & Structural Glazing Engineering
Fixed glass windows—often designated in architectural schedules as non-operable picture windows or fixed lites—play a paramount role in modern structural glazing facades. Unlike operable window sash mechanisms, fixed aluminum windows are specifically engineered to optimize daylighting, maximize uninterrupted panoramic views, and provide superior structural resistance against extreme wind loads (Positive and Negative Pressure Deflection ratios up to L/175 or L/240).
At our 10,000 m² Foshan manufacturing center, we utilize premium primary-grade 6063-T5 and 6063-T6 aluminum alloys. Profiles are extruded with uniform wall thicknesses ranging from 1.4mm for residential applications up to 3.0mm structural walls for high-rise commercial ribbon windows and storefront curtain wall framing. Surface treatments include AkzoNobel fluorocarbon (PVDF) electrostatic spraying, hyper-durable powder coating (minimum 60–80 microns thickness), and 25-micron architectural anodizing, offering resistance against salt spray corrosion for coastal installations.
PA66GF25 Thermal Insulation
Our thermal break fixed windows incorporate imported 25% glass-fiber reinforced Polyamide (PA66 GF25) thermal barrier strips. This structural separation effectively isolates interior and exterior profile sections, dramatically mitigating thermal bridging and lowering system U-factors to under 1.2 W/m²K (0.21 BTU/hr·ft²·°F).
Advanced IGU & Safety Glazing
We process Insulated Glass Units (IGU) featuring tempered safety glass, low-emissivity (Low-E) pyrolytic coatings, Argon gas filling (90%+ concentration), and warm-edge composite spacers. For hurricane zones, we integrate Kuraray SGP® or PVB laminated interlayers matching SGCC and AS/NZS 2208 certifications.
Dual EPDM & Silicone Gasketing
Zero-tolerance weatherproofing is achieved using continuous vulcanized EPDM rubber gaskets combined with Dow Corning structural silicone sealant (SSG). This eliminates water penetration under static pressure conditions exceeding 1050 Pa (ASTM E331 performance standard).

Architectural Industry Foresight
Next-Generation Fixed Window Development & Sourcing Trends
As global building energy codes tighten and architectural design aesthetics lean heavily toward transparent envelope integration, fixed glass windows are evolving beyond passive elements into active performance barriers.
1. Ultra-Narrow Sightlines & Hidden Frame Systems
Modern architectural design overwhelmingly favors ultra-minimalist, floor-to-ceiling glass connections. Future manufacturing trends center on perimeter frame structural embedding, where the aluminum extrusion is fully recessed into the building wall reveals. This creates invisible frame profiles, maximizing visual aperture while maintaining structural structural sealant adhesion along the glass perimeter.
2. BIPV & Electrochromic Smart Dynamic Glazing
Procurement forecasts indicate rapid growth in Building-Integrated Photovoltaic (BIPV) glass and electrochromic dynamic smart glass embedded within non-operable fixed window units. Fixed windows provide the ideal static structural plane for electrical wiring integration, enabling windows to automatically adjust Solar Heat Gain Coefficients (SHGC) or generate clean solar energy for commercial structures.
3. Circular Low-Carbon Recycled Aluminum
With international carbon border adjustments and LEED v4 / BREEAM sustainability standards, global real estate developers now require verified Environmental Product Declarations (EPD). Future B2B procurement favors aluminum fixed window suppliers utilizing post-consumer recycled aluminum billets extruded with hydroelectric power, reducing embodied carbon by up to 75%.
Global B2B Procurement Strategy & Digital Twin BIM Modeling
International architectural procurement has shifted dramatically from purchasing off-the-shelf standard sizes to comprehensive full-custom OEM engineering collaboration. Today’s facade consultants, general contractors, and project developers require full Digital Twin support prior to fabrication.
01. BIM LOD 400 Integration
Supply of precise Autodesk Revit families containing embedded thermal values, structural material metadata, and precise glass build-up parameters for conflict detection.
02. Finite Element Analysis (FEA)
Computerized structural stress modeling of aluminum extrusions under specified localized wind load conditions to optimize profile weight without compromising structural safety margin.
03. Full-Scale Mockup Testing
Fabrication of physical prototype units for third-party laboratory air infiltration, static/dynamic water pressure, and structural load validation prior to mass extrusion runs.

Buyer Knowledge Base
Frequently Asked Questions for B2B Window Sourcing
Detailed answers addressing structural engineering, OEM custom manufacturing, shipping logistics, and compliance verification.
What is the key structural advantage of custom OEM aluminum fixed glass windows?
Fixed glass windows (non-operable picture windows) do not require moving sash components, hinges, or operating handles. This structural simplicity allows engineers to design larger single-lite glass spans while maintaining significantly higher wind load resistance, superior air-tightness (Class 4 standard), and zero risk of water leakage through sash weatherstripping failures.
Can KARON manufacture aluminum fixed windows according to custom CAD/BIM architectural drawings?
Yes, 100% of our production is engineered to order. We review architectural schedules, opening dimensions, wind pressure parameters, and profile depth requirements. Our engineering department generates detailed shop drawings (including glass bite depth, perimeter anchoring details, and expansion joint configurations) for consultant approval prior to aluminum profile extrusion and glass cutting.
What thermal break configurations are available for fixed windows installed in extreme climates?
For cold northern or hot desert environments, we supply high-performance thermal break profiles equipped with PA66 GF25 (25% glass fiber reinforced polyamide) insulating strips ranging from 14.8mm up to 34mm width. Combined with triple-pane Low-E insulated glass units (IGU) containing Argon gas and warm edge spacers, we achieve overall window U-factors down to 0.8–1.2 W/m²K.
How are large fixed glass windows packaged to prevent breakage during international ocean freight?
All glass units and complete window frames are packed using heavy-duty, fumigated ISPM-15 compliant fully enclosed plywood crates or steel A-frame racks. Glass edges are protected with plastic corner protectors, inter-layer foam sheet cushioning, and vacuum shrink-wrap to prevent moisture ingress during containerized ocean transit.
What international glass safety certifications do KARON products carry for North America and Oceania?
Our safety glass manufacturing holds active certifications including US SGCC (Safety Glazing Certification Council) per ANSI Z97.1 and CPSC 16 CFR 1201 standards, Australia AS 2208 SAI Global StandardsMark, and New Zealand AS/NZS 2208 CSi PAS-Mark for both toughened (tempered) and laminated safety glass build-ups.
What is the typical Minimum Order Quantity (MOQ) and production lead time for OEM projects?
For custom architectural aluminum profiles and specialized glass build-ups, our typical project MOQ is 100 square meters. Standard factory production lead time is 25 to 35 calendar days following final CAD shop drawing sign-off and deposit receipt.
What surface finishes are offered to prevent corrosion in marine or coastal environments?
We recommend 70% Fluorocarbon (PVDF) coating or high-grade Qualicoat-certified powder coating with pre-anodized pretreatment. This surface specification withstands 3,000+ hours of continuous neutral salt spray testing (ASTM B117 standard) without blistering, chalking, or color fading.
