Manufactured under strict ISO 9001 and AS2047 protocols, each architectural system integrates heavy-duty aluminum extrusions tailored to withstand tropical precipitation and structural wind pressures.
Operating from Foshan, China's aluminum industrial powerhouse, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) represents over 25 years of engineering mastery, delivering certified fenestration directly to project sites across Yangon and Southeast Asia.
In equatorial and tropical maritime climates like Yangon, windows are subjected to relentless physical stress. Extreme solar thermal cycles, heavy southwest monsoon precipitation exceeding 2,500 millimeters annually, and violent squalls require far more than conventional residential joinery. DERCHI bridges the gap between precision structural fabrication and regional adaptability. By integrating our Zero-Error Manufacturing standard, every extrusion cut, pneumatic miter, crimped mechanical joint, and continuous multi-layer EPDM seal is inspected to sub-millimeter tolerances before container loading.
Backing our fabrication integrity is an extensive research apparatus supported by over 100 national invention and utility patents—including our breakthrough Four-Side Six-Point Lock mechanism. From landmark hotels like Hilton and Atour to luxury compounds in Beverly Hills and Ruyi Lake, over 18,000 global installations demonstrate the long-term reliability of our certified aluminum envelope solutions.
Addressing the unique microclimatic, spatial, and security criteria of Yangon's luxury estates, riverside condominiums, and commercial centers.
Luxury multi-story private estates along Inya Lake demand seamless connections between landscaped garden terraces, natural breezes, and air-conditioned interiors. Our custom heavy-duty aluminium folding windows and bi-fold doors open up to 90% of structural rough openings without unsightly intermediate vertical posts. High-inertia structural mullions prevent frame sag across wide 6-meter apertures, while flush sub-sills allow uninterrupted transition between outdoor pools and interior living lounges.
Yangon River frontage and high-density towers across Dagon and Yankin encounter extreme wind-driven torrential rains during the May-to-October monsoon season. Traditional sliding or folding systems frequently fail via track overflow. DERCHI bifold and folding window units incorporate multi-tiered step-drainage tracks, pressure-equalized hollow chambers, and vulcanized EPDM compression gaskets that exceed 600 Pa water penetration resistance, preventing capillary water backflow under high gusts.
In historic commercial districts such as Kyauktada, Pabedan, and upscale restaurants along Strand Road, renovations require modern thermal performance while respecting narrow streetscapes. Our slimline bifold servery windows fold compactly against exterior walls, enabling cafes and retail spaces to activate pedestrian shopfronts during dry evenings while maintaining security and thermal insulation when closed.
How progressive developers and architects in Yangon are shifting from uninsulated aluminum to engineered thermal systems to combat energy costs and climate challenges.
The building envelope market in Myanmar is undergoing a decisive technological transition. Historically, Yangon residential and commercial developments relied upon thin-gauge 1.0mm–1.2mm non-thermal aluminum frames paired with single 5mm or 6mm annealed glass. These configurations act as thermal conductors, dumping ambient exterior heat (which frequently exceeds 38°C with 85% relative humidity in April and May) straight into conditioned indoor spaces. With rising electricity costs and power grid variations in Yangon, real estate developers are prioritizing long-term HVAC efficiency.
Incorporating 24mm PA66 fiberglass-reinforced nylon thermal break strips eliminates direct metal-to-metal thermal bridges, reducing frame U-values from 5.8 W/m²K down to under 2.2 W/m²K.
Urban traffic in central Yangon and industrial noise necessitate double-glazed IGUs (e.g., 6mm Low-E + 12Ar + 6mm Clear) providing sound attenuation greater than 38 dB alongside low Solar Heat Gain Coefficients (SHGC < 0.32).
Tropical UV radiation and seasonal moisture cause standard powder coatings to chalk or peel. DERCHI applies AkzoNobel PVDF fluorocarbon coatings capable of withstanding 3,000 hours of continuous salt-spray and ultraviolet weathering.
Bi-fold sash weights can exceed 90kg per leaf. Heavy-duty 316 stainless steel top-hung multi-roller carriages ensure frictionless, quiet sash operation without track degradation or binding over decades.
