Every roof glazing unit undergoes hydrostatic pressure simulation and thermal chamber checks before container loading at Foshan Port.
Engineered for Thailand's High-Rise & Tropical Villa Real Estate
Bangkok’s dense urban grid and tropical climate present extreme design criteria: equatorial ultraviolet radiation, prolonged flash downpours, high acoustic smog, and aggressive roof expansion. Our systems solve these challenges through targeted engineering.
High-Rise Atrium & Loft Roof Windows
- Thermal-Break Shield: Polyamide PA66 thermal barrier prevents heat bridge transfer, slashing AC electricity consumption by up to 34%.
- Acoustic Isolation: Double laminated soundproof glass units (PVB / SGP) reduce central Bangkok traffic and sky-train rumble from 80dB to under 32dB.
- Motorized Rain Sensors: Automated actuators synchronize with precipitation sensors to close operable roof sashes instantly during sudden afternoon storms.
Luxury Villas & Coastal Sunroom Roofs
- Monsoon Flashing Kits: Custom stepped-drainage flashing trays channel high-volume downpours away from tile, metal-deck, or concrete roof curbs.
- Fluorocarbon (PVDF) Coatings: High-durability coatings resist coastal humidity, salt-spray corrosion, and UV discoloration across 25+ years.
- Anti-Shatter Armored Glass: Top-tier tempered-laminated glass configurations prevent impact penetration from falling coconuts or debris during squalls.
Shophouse Conversions & Boutique Hotels
- Natural Stack Ventilation: Operable pivot skylights create a chimney effect, venting hot air trapped in multistory shophouse lightwells.
- Low-E Daylight Optimization: Maximizes natural lighting into deep interior floorplans without introducing blinding glare or high thermal loads.
- Bespoke Structural Framing: Custom profile sizing adapts seamlessly to historical brick facades, concrete post-and-beam, and modern steel purlins.
Thailand Fenestration Trends & Green Building Standards
Developers and architects in Bangkok are transitioning rapidly from generic aluminium framing to high-performance, envelope-engineered fenestration driven by the following four market factors.
TREES & LEED Energy Compliance
The Thai Green Building Institute’s TREES rating system and international LEED benchmarks now penalize uninsulated roof penetrations. High Solar Heat Gain Coefficient (SHGC) glass with double silver Low-E coatings is now mandatory to pass envelope energy compliance.
Intense Urban Heat Island (UHI) Effect
Bangkok's dense concrete topology creates nighttime heat retention of up to 4°C above surrounding regions. Thermally broken aluminium extrusions prevent continuous inward thermal bleeding through roof framing, maintaining interior chill created by HVAC systems.
Integrated Smart Home Automation
Luxury residential and hospitality projects demand roof windows integrated with KNX, Zigbee, or Tuya building automation. Clients require remote phone app controls, wind/rain override triggers, and synchronized interior solar-shading blinds.
Direct Factory B2B Procurement
Main contractors in Bangkok are increasingly bypassing third-party traders to collaborate directly with original Foshan factories. This direct supply chain eliminates 20-30% middleman markups and guarantees shop-drawing coordination with structural engineers.
Our 8-Step Direct Export & Customization Workflow
We eliminate communication gaps between overseas architectural concepts and manufacturing execution through a rigorous, documented process.
Architectural Drawing Review
Our facade engineering team analyzes your CAD/BIM plans, checking structural wind load, roof pitch, water runoff paths, and opening requirements.
R&D & Thermal Simulation
We configure optimal glass thicknesses, Low-E coatings, warm-edge spacers, and alloy profiles to meet your target U-value and acoustic STC ratings.
Itemized Technical Proposal
Receive comprehensive structural proposals, section extrusion details, hardware specifications, and direct container factory pricing within 48 hours.
Shop Drawing Sign-Off

Order Scheduling & Deposit
Production scheduling is locked inside our automated Foshan facility upon commercial agreement, guaranteeing predictable delivery timelines.
Site Opening Verification
We review contractor on-site curb measurements or laser scans before cutting profiles, avoiding millimeter discrepancy during installation.
Intelligent CNC Manufacturing
Extrusions are CNC machined, glazed, corner-injected with structural adhesive, and water-spray tested according to 360° QC criteria.
Installation Guidance & Support
We supply full video installation tutorials, shop manuals, and on-site engineering supervision for major commercial projects in Thailand.
Internationally Recognized Safety & Energy Certifications
Every roof window and architectural fenestration unit is verified by accredited third-party laboratories to satisfy rigorous international building codes.
Procurement & Technical Questions
Navigating cross-border fenestration procurement requires clear technical clarity. Here are detailed responses to the most critical technical and logistical questions asked by architects, general contractors, and developers across Thailand.
How do your roof windows prevent water leakage during severe Bangkok monsoon storms?
Roof windows are subjected to far greater hydraulic pressure than vertical windows. Our roof systems integrate triple-seal EPDM synthetic rubber gaskets, custom stepped aluminium drainage flashing trays designed for tile, concrete, or metal standing seam roofs, and secondary weep channels that divert micro-condensation to the exterior. Every prototype is factory-tested under 600 Pa cyclic water spray pressure, guaranteeing zero water ingress even under tropical storm rainfall.
Can your glass configurations resist intense tropical solar heat and UV radiation in Thailand?
Yes. We specifically engineer glass units for low-latitude tropical climates using Double Silver or Triple Silver Low-E insulated glass units (IGU) filled with 95% argon gas. This achieves an exceptionally low Solar Heat Gain Coefficient (SHGC) between 0.22 and 0.28, reflecting up to 82% of infrared heat radiation while transmitting over 65% of visible daylight, drastically reducing air-conditioning loads.
What is the typical shipping lead time and customs procedure from Foshan to Bangkok Port?
Thanks to our factory’s strategic proximity to Pearl River Delta container ports (Nansha/Shekou), ocean freight transit to Bangkok (PAT Port / Laem Chabang) typically takes only 5 to 7 days. Production lead times range from 20 to 30 days depending on profile finish and glass customization. We provide full export documentation including Form E (ASEAN-China FTA) to allow Thai clients to enjoy zero or significantly reduced import customs tariffs.
Are your skylights and roof windows compatible with smart home and building automation systems?
Yes. We offer concealed 24V DC electric chain actuators and linear motors that integrate natively into central building management systems via KNX, RS485, Zigbee, or dry-contact relays. Automated roof windows can be paired with ambient temperature sensors, internal CO2/smoke sensors, and exterior weather stations to close automatically when rain is detected.
Can DERCHI manufacture custom dimensions and match specific architectural RAL colors?
Every unit we produce is fully customized to your structural openings and roof pitch angles (from 15° to 85°). Our in-house electrostatic powder coating and fluorocarbon (PVDF) lines match any RAL architectural color code, as well as specialized anodized, metallic, or realistic anti-UV wood-grain finishes that resist fading under equatorial sun exposure.
