All assemblies are CE marked, AS 2047 tested, and ISO 9001 certified. Engineered in our 180,000 m² smart plant to withstand tropical humidity, harmattan sandstorms, and coastal saline erosion across West Africa.
Operating from Foshan, Guangdong—the global epicenter of high-end architectural extrusions—we eliminate trading markups. We deliver verified structural performance directly to commercial and high-end residential jobsites across Nigeria.
Every batch of vertical sliding sash windows passes rigorous air permeability (EN 12207), water tightness (EN 12208), and structural resistance checks before leaving the factory.
Our structural engineering desk models wind loads, rough opening structural clearances, and glass thermal stresses, issuing fully dimensioned DWG shop drawings free of charge.
Products are sealed in multi-layer pearl foam, scratch-resistant polymers, and fumigated steel-corner reinforced wooden crates designed to withstand rough container drayage through Apapa port.
From intense marine salt spray along the Atlantic corridor to extreme harmattan airborne dust, our vertical sliding assemblies are configured for regional microclimates.
Heavy moisture and airborne marine chlorides cause rapid pitting on ordinary aluminum. Our installations feature Qualicoat Class 2 fluorocarbon (PVDF) finishes that remain pristine despite harsh Atlantic exposure.
Designed with multi-chamber profiles, security spiral balances, and double-glazed acoustic laminated glass. They deliver vital sound attenuation (Rw 38dB+) and thermal isolation from the high central plateau heat.
Large structural spans handle high wind pressures at upper levels. Continuous brush-weatherstripping prevents air infiltration, dramatically reducing central HVAC loads and generator fuel consumption.
Dry, dust-laden Harmattan winds challenge traditional tracking. Our sealed track profiles and precision-engineered spiral balance systems prevent fine dust intrusion while maintaining smooth sash motion.
Driven by rapid urbanization, high off-grid energy costs, and an expanding premium real estate sector, developers across West Africa are changing how they specify sliding window systems.
With commercial real estate heavily reliant on captive diesel power generation, low-E double glazing combined with thermally broken sash systems has become standard. They cut indoor solar heat gain by up to 64%, noticeably reducing HVAC electrical draw.
Rot, termite attack, and swelling from tropical monsoons have made wooden sash windows impractical long-term. Extruded 6063-T5 aluminium preserves classical aesthetic sightlines while providing decades of rot-free durability.
Modern developments demand built-in security. Our vertical sliding sash windows combine heavy-duty crescent locks with marine-grade 304 stainless steel security mesh, keeping pests out without requiring unsightly burglar bars.
| Performance Characteristic | Guangdong Dejiyoupin Architectural Spec | Standard Market Sliding Window | Direct Project Advantage |
|---|---|---|---|
| Aluminium Alloy Profile | Primary Virgin 6063-T5 / 6063-T6 (2.0mm - 2.5mm wall thickness) | Recycled scrap blend (1.1mm - 1.2mm wall thickness) | Zero warping under gusting equatorial storm winds; lifetime structural stability. |
| Surface Protection | AkzoNobel PVDF Fluorocarbon or 25µm Hard Anodized | Standard Mill finish or basic spray-painting | Immune to peeling, fading, chalking, and salt spray degradation in coastal regions. |
| Counterbalance System | Precision Calibrated Spiral / Constant Force Balances | Friction stays or manual weight pulleys | Effortless single-finger sash movement; stops at any height without slamming. |
| Weatherproofing Seals | Continuous EPDM Gaskets + High-Density Silicone Piles | Low-grade PVC or scrap rubber beading | Stops tropical rain leaks and prevents fine harmattan dust infiltration. |
| Acoustic & Thermal Core | 5mm + 12A + 5mm Argon Gas Filled Double Tempered Low-E | Single 4mm or 5mm clear floating glass | Cuts outdoor ambient street noise by 38dB; minimizes internal cooling load. |
