Triple Glazed
Exterior structural-grade architectural aluminum skin shielding interior North American oak or teak. Delivers STC 42+ sound attenuation against heavy Metro Manila urban highway noise.
Architectural
Anodized corrosion-resistant extruded frames fitted with impact-resistant frosted or tinted safety glass panels. Engineered with wind-load reinforced torsion spring drive tracks.
Sourcing glazed windows and doors for Metro Manila and greater Luzon requires solving three structural challenges: Type 5 typhoon wind loads, tropical humidity condensation, and intense urban acoustic pollution.
During the habagat monsoon and cyclonic storms crossing Luzon, coastal high-rises experience extreme positive and negative surface pressure exceeding 3000 Pa. Standard residential frames warp, causing severe water penetration around weep holes.
DERCHI systems utilize AS 2047 N6 tested structural aluminum alloy (6063-T6) featuring pressure-equalized internal drain channels, stepped sills, and continuous santoprene EPDM gaskets that safeguard interiors against water ingress at 450+ Pa water test pressure.
Air conditioning accounts for more than 60% of commercial and residential building power consumption across Metro Manila. Monolithic glass windows radiate ambient tropical heat directly indoors, overloading chillers and inflating utility costs.
Our export configurations incorporate PA66 thermal barriers coupled with double-glazed units (6mm + 12Ar + 6mm) using double-silver Low-E coating. This cuts Solar Heat Gain Coefficient (SHGC) below 0.28 while preserving 65% natural visible daylight transmittance.
Continuous heavy vehicular traffic along EDSA, light rail transit corridors, and bustling commercial strips in Pasay generate ambient street noise exceeding 78 to 85 dBA, interfering with high-end residential livability and executive workspaces.
By engineering asymmetric glass laminates (e.g., 6mm Low-E + 1.14mm PVB + 6mm + 12A + 8mm tempered), DERCHI fenestration achieves an Acoustic Sound Transmission Class (STC) rating of 42+ dB, filtering low-frequency diesel and rail hum to near library-quiet standards.
A direct technical comparison highlighting performance disparities critical for Philippine developers and general contractors.
| Performance Parameter | Common Philippine Market Windows | DERCHI Heavy-Duty Architectural Series | Philippine Engineering Advantage |
|---|---|---|---|
| Aluminium Alloy Profile | 1.0mm - 1.2mm Non-Thermal Extrusion (Recycled billet) | 2.0mm - 3.0mm 6063-T6 Primary Extrusions | Resists structural flexing under Category 4-5 typhoon gust conditions. |
| Thermal Insulation | Non-thermal conductive frames (Aluminum conducts heat directly) | Polyamide PA66GF25 Engineered Thermal Barrier | Eliminates frame condensation and slashes indoor HVAC power consumption. |
| Glazing Specification | Single 5mm - 6mm Clear or Tinted Glass | Double / Triple Tempered Low-E + Argon Gas Cavity | Cuts radiant infrared heat transmission while retaining indoor cooling. |
| Surface Protection | Standard Mill finish or 15-micron Anodizing | AkzoNobel / PPG PVDF Fluorocarbon (30+ Year Warranty) | Immune to sea-salt air degradation and corrosive coastal spray along Manila Bay. |
| Sealing Compound | Ordinary PVC or industrial silicone caulk | Multi-chamber Vulcanized Santoprene EPDM Seals | Stays pliable and airtight under persistent UV exposure without cracking. |
| Certification Standards | Uncertified or nominal workshop testing | AS 2047 (Australia), CE, ISO 9001, NFRC, CSA | Full compliance with International Building Code (IBC) and BERDE standards. |
Leading property developers in the Philippines (such as Ayala Land, Megaworld, and Robinsons Land) along with top architectural firms are reshaping building envelope criteria.
With national green building codes enforcing mandatory energy reductions, single-pane sliding frames are rapidly being phased out in institutional bids. Double-glazed thermal systems are now the primary spec for LEED and BERDE certifications.
High-end residential estates in Nuvali and Tagaytay demand floor-to-ceiling glass envelopes. Narrow-profile framing with structural perimeter deadweights supports single panel loads over 400kg, achieving panoramic tropical views without sacrificing stability.
Catastrophic typhoons have caused architectural window failures via debris impact and negative wind pressure suck-out. Procurement contracts now demand documented structural deflection test reports exceeding 3.0 kPa.
Entrance architecture across Metro Manila has shifted from mechanical mortise sets to fully concealed biometric access, RFID entry, and IoT motorized operators tied directly into centralized home automation ecosystems.
Backed by Guangdong Dejiyoupin Doors and Windows Co., Ltd., we combine Chinese industrial fabrication scale with direct export services aligned to Southeast Asian requirements.
Based in Foshan, Guangdong—the world’s primary aluminum industrial cluster—our factory is minutes away from Nansha and Shekou ports. Ocean transit to Manila South or North Harbor requires only 3 to 5 sailing days, minimizing project lead times.
Prior to extrusion cut-off, our dedicated structural drafting team provides comprehensive shop drawings, structural anchor calculations, wind-load analysis, and sub-frame connection detailing tailored to Philippine concrete frame conventions.
We work in the exact same time zone as Manila. Our engineering estimators provide instant architectural clarifications, quote revisions, site coordination calls, and video quality checks without cross-continental scheduling delays.
Clear technical, logistical, and custom clearance answers for developers, quantity surveyors, and homeowners importing into the Philippines.
For elevations above the 10th floor in Manila Bay and BGC, we recommend a minimum structural profile thickness of 2.0mm to 3.0mm in 6063-T6 alloy. Thin 1.2mm profiles will flex during super typhoons, breaking silicone seals and causing severe water entry. Our AS 2047 N6 compliant systems are engineered specifically for these extreme cyclonic pressures.
All products undergo 5-layer export packaging: protective film over powder-coated surfaces, EPE high-density foam buffering, edge corner protectors, fully sealed moisture-proof poly wrap, and heavy ISPM-15 certified non-coniferous fumigated plywood crates with steel strapping. Each crate includes lifting skids for forklift handling.
Yes. Under the ASEAN–China Free Trade Agreement (ACFTA), we issue official Form E certificates of origin. When submitted to the Philippine Bureau of Customs (BOC), Form E frequently reduces the standard Most Favored Nation (MFN) import tariff from 7%–10% down to 0% duty on eligible aluminium window and door tariff lines, leaving only local VAT.
Every shipment is organized with clear labeling linked to your architectural door/window schedule. We provide detailed 3D exploded assembly diagrams, frame anchoring schematics, weep drainage setups, and step-by-step video installation manuals. Our English-fluent engineering specialists are on standby on GMT+8 for real-time video site support.
