Typhoon Habagat Resistance
The annual Southwest Monsoon (Habagat) combines continuous sustained winds with relentless horizontal rain. Traditional sliding profiles rely on weep holes that back-siphon water into interior plasterboards under dynamic wind pressure. Our swing/casement systems utilize continuous EPDM automotive-grade compression gaskets with heavy-duty four-bar stainless friction stays, sealing completely tighter as external air pressure surges.
- Stepped sill drainage chambers with internal baffle check valves
- Four-sided multi-point perimeter latching preventing sash deflection
- Reinforced wall thickness from 1.6mm up to 2.5mm on structural frames
Coastal Saline Protection
Properties in coastal centers such as Cebu City, Davao, Batangas, and Palawan suffer aggressive airborne chloride attacks. Standard zinc alloy latches and anodized coatings oxidize rapidly, leading to hinge seizure. DERCHI specifies grade 304 and 316 stainless steel friction hinges, transmission gear rods, and PVDF fluorocarbon coatings that exceed 20-year coastal exposure without pitting.
- Fluorocarbon (PVDF) resin application meeting AAMA 2605 specifications
- Anti-friction nylon bushings on pivot arms for salt crystal clearance
- Electrolytic insulation pads preventing bi-metallic contact galvanic corrosion
Solar Heat Gain & Urban Acoustics
With year-round high solar irradiance and cooling costs representing up to 60% of commercial power bills across Metro Manila, thermal-break swing windows are essential. Integrated with 24mm insulated double glazing (6mm Low-E + 12A Argon + 6mm Clear), our systems drop the Solar Heat Gain Coefficient (SHGC) below 0.28 while delivering exceptional sound insulation against bus routes and elevated skyways.
- Polyamide PA66 thermal barrier strips eliminating thermal conduction
- Acoustic polyvinyl butyral (PVB) interlayer lamination for deep acoustic isolation
- Drastic reduction in HVAC tonnage sizing for LEED and BERDE compliance
Contextual Field Applications
Localized Application Scenarios in the Philippines
From high-density central business districts to remote ultra-luxury island villas, our swing systems adapt to exact architectural and regional zoning requirements.
High-Rise Condominiums (BGC, Makati, Ortigas)
High-elevation units experience extreme wind shearing forces along with severe road acoustic pollution. DERCHI outward-opening swing casements fitted with restrictor hinges provide safe, micro-ventilation while providing impenetrable acoustic and water-tight envelopes during major weather disruptions.
- Opening restrictor arms limiting sash angle to prevent accidents
- Concealed multi-point lock operators for sleek interior aesthetics
- Full compliance with developer wind load and deflection criteria
Subdivision Villas (Forbes Park, Alabang, Nuvali)
Philippine luxury estates prioritize expansive glass openings, natural cross-ventilation, and stringent physical security. Integrating diamond security mesh screen doors and swing windows allows free airflow during cool evenings while repelling insects, pests, and unauthorized forced entry attempts.
- Integrated heavy-duty 304 marine-grade diamond mesh screen tracks
- Architectural wood-grain and custom powder finishes to match gate structures
- Subtle sash lines maximizing sightlines into manicured lanai gardens
Island Resorts & Coastal Retreats (Boracay, Siargao)
Direct exposure to breaking waves, driving coastal sand, and tropical depressions demands corrosion-proof hardware. Our thermal-break aluminum French swing doors and paired swing windows maintain smooth operable friction balances without sticking or corroding over decades of resort service.
- Custom PVDF coastal coatings tested to ASTM B117 standards
- Laminated tempered safety glass resistant to windborne storm debris
- Effortless integration with wide-spanning accordion bifold exterior doors
Market Foresight & Building Standards
Philippine Fenestration Development & Architectural Trends
How progressive Philippine building codes, green building certifications, and urbanization patterns are accelerating the shift from standard sliding windows to high-performance swing systems.
Transitioning Toward High-Air-Tightness & BERDE Certification
Historically, the Philippine fenestration market relied heavily on generic 798 or 900 series single-glazed aluminum sliding windows due to low upfront manufacturing costs. However, escalating electricity tariffs across the country have caused a permanent structural paradigm shift among Tier-1 developers, architects, and corporate homeowners.
With the adoption of the Philippine Green Building Code (GB Code) and green certifications such as BERDE and LEED, building envelopes must achieve strict thermal transmittance limits (U-value ≤ 3.0 W/m²·K). Sliding windows intrinsically leak conditioned indoor air around brush pile weatherstrips. In contrast, modern aluminum swing and casement systems leverage compression-sealed perimeter EPDM technology, dropping air infiltration rates to near zero, thereby lowering building energy consumption by up to 32% annually.
Surge in High-Performance Modern Architectural Styles
Contemporary Philippine residential and commercial architecture is characterized by expansive floor-to-ceiling glass, clean minimalist sightlines, and transitional indoor-outdoor living. Architects are actively pairing high-span aluminum French swing doors with narrow-profile casement swing windows, providing unhindered visual continuity while delivering unmatched structural rigidity during major storms.

Procurement Intelligence
Frequently Asked Questions by Philippine Buyers & Developers
Key technical, logistical, and commercial inquiries from developers, contractors, and architects specifying windows for Philippine projects.
How do DERCHI aluminum swing windows prevent water leakage during extreme Habagat typhoons?
Our swing/casement systems are engineered around the "Rain Screen Principle" utilizing a pressure-equalized decompression chamber. Unlike typical sliding windows that rely solely on surface drains, our swing profiles use continuous automotive-grade EPDM gaskets that are compressed when the multi-point handle engages. As external typhoon wind pressure increases, it presses the operable sash tighter against the frame's internal gasket barrier. Independent water-tightness tests confirm performance up to 600 Pa without internal siphoning.
What are the port-to-port shipping timelines and customs documentation from Foshan to Manila or Cebu?
Direct ocean transit from Nansha/Shekou (Guangdong) to Manila South Harbor or MICP typically takes only 3 to 5 days, and approximately 6 to 9 days to Cebu or Davao. We provide comprehensive export documentation to support swift clearance with the Bureau of Customs (BOC), including Form E (ASEAN-China Free Trade Area preferential tariff certificate), Commercial Invoices, detailed Packing Lists with itemized crate numbers, and Bill of Lading (B/L).
Can your profiles integrate with local architectural grid sizes and customized Philippine wall jambs?
Yes. 100% of our production is made to measure. Our engineering department develops complimentary CAD shop drawings based directly on your architectural opening schedules. We manufacture custom sub-frames, plastering fins, and installation anchor brackets compatible with both standard 100mm/150mm concrete hollow block (CHB) walls and modern precast cast-in-place building systems commonly used across the Philippines.
How do you protect aluminum finishes and hardware against saline coastal air corrosion?
For seaside and island projects, we utilize PPG or AkzoNobel PVDF fluorocarbon coatings that satisfy the rigorous AAMA 2605 specification (minimum 3,000-hour neutral salt spray resistance). In addition, all operating components—including four-bar friction hinges, stays, transmission bars, and fastening screws—are specified in grade 304 or 316 stainless steel to eliminate the possibility of oxidation and hardware seizure.
Can you incorporate insect screens and anti-burglar diamond mesh into casement systems?
Absolutely. We produce integrated twin-track and triple-track systems combining the exterior glass swing window with an interior hinged 304 marine-grade diamond security mesh screen. This configuration allows homeowners to open the primary glass window during pleasant weather to achieve full cross-ventilation while maintaining secure insect protection and physical anti-intrusion security.
What certifications and third-party test reports do you provide for project consultant approvals?
Our window and door lines are backed by rigorous international standard certifications, including AS2047 (Australian Standards wind, air, water, and operating force test), ISO9001 quality management, CE European conformity, and CSA/NFRC thermal performance ratings. Full third-party physical test reports are furnished prior to container dispatch for smooth sign-off by structural engineers and QA/QC consultants.
