Explore ProductA rigorous engineering approach to aluminum exterior storm window fabrication: optimizing structural resilience, cyclical wind loading, and fenestration efficiency.
We utilize prime architectural-grade 6063-T6 and 6061-T6 aluminum alloys. Precision extrusion parameters control grain boundary precipitation, achieving a tensile yield strength exceeding 215 MPa. This structural rigidity prevents frame deflection during cyclic hurricane gust pressures and prevents permanent sash warping under thermal expansion stresses.
Traditional aluminum envelopes act as thermal bridges. Our storm window assemblies incorporate glass fiber-reinforced PA66 GF25 polyamide thermal barriers. This separation drops U-factors down to passive-level thresholds (< 0.28 BTU/h·ft²·°F / 1.6 W/m²K), completely mitigating internal sash condensation and minimizing HVAC thermal transfer cycles in extreme climates.
Our drainage and weatherproofing strategy uses vulcanized EPDM triple-compression gaskets paired with staggered weep chambers. Even under driving rain backed by 4500 Pa positive wind loads (AS 2047 N6 Compliance), internal pressure-equalized drainage tracks redirect hydrostatic moisture away from structural wall bucks, guaranteeing zero internal leakage.

DERCHI is the flagship brand of Guangdong Dejiyoupin Doors and Windows Co., Ltd., ranking consistently among the Top 10 fenestration manufacturers in China. Operating across a sprawling 180,000 square meter intelligent production base, we combine German precision tooling with lean automated lines.
For more than a quarter-century, our sales engineering teams have worked alongside general contractors, architectural specifiers, and high-volume facade dealers in the United States, Canada, Australia, and the Middle East. Because every step—from billet extrusion and thermal crinkle-coating to CNC miter-cutting and IGU glazing—is executed in-house, overseas partners bypass commercial brokers while gaining fully customized shop drawings, mill certificates, and strict delivery timelines.
Where architectural demand, stringent coastal building codes, and green building certifications are driving the next 5 years of fenestration procurement.
With coastal hurricane patterns intensifying across Florida, the Caribbean, and Australasia, standard storm windows are obsolete. Builders now mandate dual-impact PVB/SentryGlas® laminates capable of sustaining repetitive 2x4 projectile strikes without envelope rupture.
Architects no longer compromise on daylight apertures. High-moment-of-inertia extruded aluminum profiles allow profile sightlines under 45mm while maintaining wind deflection parameters, supporting floor-to-ceiling glass in luxury estates.
Procurement departments favor recycled-content "green aluminum" extruded using renewable hydropower. When paired with multi-cavity thermal insulation, DERCHI assemblies directly contribute up to 12 LEED v4 building credits.
Supply chain compression is the defining trend. General contractors are sidestepping regional intermediaries to contract directly with automated tier-1 factories that provide verified 3D CAD modeling, BIM objects, and unified maritime export packaging.
