Certified Storm Windows & Architectural Enclosure Systems
Every profile is extruded from 6063-T6 or 6061-T6 structural aluminum, equipped with multi-point stainless steel hardware, and tested to withstand extreme cyclonic winds, salt-spray corrosion, and thermal stress.

Anatomy of Heavy-Duty Aluminum Storm Windows
Unlike standard residential glazing, certified aluminum storm windows serve as the primary defensive barrier against extreme barometric variations, cycling structural wind loads, and windborne missile debris.
Alloy Metallurgy: 6063-T6 Extrusions
We mandate architectural 6063-T6 grade aluminum profiles with uniform minimum wall thicknesses between 2.0mm and 3.5mm. This prevents profile torsion under peak suction pressure conditions (+90 / -110 PSF) commonly measured during Category 4 and 5 hurricanes.
Impact Interlayer: SGP vs. PVB
For high-velocity hurricane zones (HVHZ), our laminated configurations deploy Kuraray SentryGlas® (SGP) ionoplast interlayers, delivering five times the tear strength and one hundred times the rigidity of conventional PVB to keep envelopes sealed post-glass fracture.
Cascading Differential Drainage
Standard sliding profiles suffer water infiltration due to sill track flooding. Our internal design utilizes stepped sill extrusion geometries with internal baffle weep holes, ensuring water repellency up to 720 Pa under torrential monsoon rainfall.
| Performance Characteristic | Commercial Grade Storm Windows (DERCHI) | Standard Residential Aluminum | Compliance Test Benchmark |
|---|---|---|---|
| Structural Wind Load (Ultimate) | > 5,000 Pa (Design Pressure ±100 PSF) | 1,200 – 1,800 Pa (DP ±30 PSF) | ASTM E330 / AS 2047 N6 |
| Impact Resistance (Large Missile) | 9 lb 2x4 lumber at 50 ft/s (Pass Level D & E) | Non-rated / Shatters completely | ASTM E1886 / ASTM E1996 |
| Thermal Transmittance (U-Factor) | U ≤ 1.4 W/m²·K (0.25 BTU/hr·ft²·°F) with PA66 Break | U > 4.8 W/m²·K (No thermal barrier) | NFRC 100/200 / ISO 15099 |
| Water Penetration Resistance | Zero leakage at 720 Pa (15.0 PSF) cyclic water test | Fails at 150 – 250 Pa | ASTM E547 / AAMA 501.1 |
| Surface Protection Finish | AAMA 2605 Qualicoat Class 3 PVDF / Fluorocarbon | Standard powder coat (<40 μm) | 3,000-hr Salt Spray ASTM B117 |
Global Procurement & Engineering Trends (2025–2030)
As structural engineering standards tighten worldwide in response to climate volatility, B2B volume buyers, developers, and general contractors must navigate evolving building regulations.
Decarbonization & Low-Carbon Aluminum
Global architectural specifications increasingly stipulate embodied carbon thresholds. Tier-one Chinese manufacturers are actively shifting toward hydro-powered smelters for billet extrusion, reducing Scope 3 carbon footprints down to 4.0 kg CO2e per kg of finished aluminum alloy without compromising structural modulus.
Deep Integration of Smart Glazing
The convergence of electrochromic dynamic glass with storm-rated multi-pane cassettes is accelerating. Commercial high-rise developments demand impact resistance alongside automated solar heat gain modulation (SHGC adjustment from 0.41 down to 0.09) linked directly to central building automation protocols.
Prefabricated Unitized Facade Systems
Rising on-site labor overheads in the United States, Australia, and Southeast Asia have led to a 42% increase in factory-glazed, fully unitized storm window orders. Sourcing pre-assembled, structurally silicone-glazed assemblies reduces site installation cycles from weeks to days while guaranteeing strict factory QC.
