Explore our flagship architectural fixed windows engineered for extreme structural performance, maximum solar transmittance, and superior sound insulation across commercial and luxury residential applications.
The global architectural fenestration sector is undergoing a structural paradigm shift driven by stringent energy efficiency mandates, net-zero carbon building standards, and increased frequency of extreme weather events. Aluminum fixed picture windows—non-operable glazing units configured within extruded aluminum framing profiles—have transitioned from decorative architectural elements to critical load-bearing, thermal-regulating facade components.
Modern commercial developments demand U-factors below 0.22 BTU/h·ft²·°F. Advanced thermal-break technology utilizing fiberglass-reinforced Polyamide (PA66 GF25) pressure-extruded bars isolates internal and external aluminum chambers, mitigating thermal bridging across severe climate zones.
Architectural preference for slim sightlines and uninterrupted daylighting has accelerated demand for oversized floor-to-ceiling fixed glass walls. Factory-engineered units now accommodate wind loads exceeding 5000 Pa while maintaining air infiltration rates below 0.05 L/s·m².
Coastal and tropical developments require stringent hurricane impact performance. Fixed window assemblies featuring multi-layer PVB/SGP laminated safety glass withstand high-velocity missile impacts (HVHZ certified) without structural framing deflection or envelope breach.
Fixed aluminum picture windows eliminate the mechanical wear points, compression seal degradations, and perimeter air leakage inherent in operable sash designs. By establishing a continuous structural silicone seal (SSG) directly bonding the Insulated Glass Unit (IGU) to extruded 6063-T5 aluminum framing, fixed systems deliver unmatched acoustic dampening (STC up to 48dB) and zero maintenance overhead for high-rise facades.
The following matrix details the rigorous physical and structural parameters governing our export-grade aluminum fixed window series. All metrics reflect third-party laboratory evaluations verified under NFRC, AAMA, ASTM, and AS2047 protocols.

Our fixed windows utilize multi-chamber Insulated Glass Units (IGUs) incorporating high-purity Argon gas fill (90%+ retention over 25 years), warm-edge stainless steel/polypropylene composite spacers, and dual-seal polyisobutylene (PIB) primary seals with silicone secondary structural backing. Double and triple Low-E soft-coat configurations eliminate 99.5% of harmful UV radiation while optimizing Visible Light Transmittance (VLT up to 72%).
Unlike conventional uninsulated aluminum frames that rapidly conduct heat, our systems integrate Technoform® or custom-engineered PA66 GF25 thermal strips ranging from 14.8mm to 34mm in depth. This thermal barrier prevents interior condensation formation during sub-zero exterior temperatures and reduces HVAC cooling loads in tropical and equatorial climate installations.
Grandex Door Solutions Co., Ltd. combines advanced European automated manufacturing lines with stringent Quality Assurance protocols to serve commercial real estate developers, facade contractors, and door/window distributors globally.
Established in 2014, Grandex Door Solutions Co., Ltd. operates an integrated manufacturing ecosystem backed by a dedicated 45-member Quality Assurance (QA) team. Supported by strict ISO 9001 certified internal testing and third-party laboratory verification, our QA engineers execute 100% incoming raw material checks, dimension tolerance laser scans, corner crimping mechanical shear tests, and water-tightness chamber testing before packaging.
Driven by an active R&D division with 85 specialized fenestration engineers, we introduced 120 new window and door designs last year. We provide comprehensive turn-key engineering solutions, including die profile design, custom dimensions, multi-point security hardware integration, specialized surface powder coatings (AkzoNobel / PPG), and decorative/structural acoustic glass panels designed for North American and European regulatory markets.
From architectural raw aluminum billet extrusion to intelligent CNC machining, corner sealing, and dynamic load testing, our 35,000 m² factory guarantees micron-level fabrication precision for every fixed window profile leaving our production line.
Navigating cross-border building code requirements requires direct technical alignment with international standards organization protocols. Grandex Door Solutions Co., Ltd. manufactures products specifically configured to pass regional compliance audits across key global territories.
