Engineered for Southeast Asia's Climate
Window and door failures in the region rarely come from appearance; they come from wind, water, heat and salt. Here is how we specify against each one.
Typhoon & Wind Load
Reinforced mullions, multi-point locking and laminated glass options, checked against project wind-load requirements.
Monsoon Water-Tightness
Raised sills, concealed drainage channels and EPDM compression seals to manage driving tropical rain.
Heat & UV Control
Thermal-break profiles with Low-E insulated glass to cut solar heat gain and air-conditioning costs.
Humidity & Coastal Corrosion
Durable powder-coated or fluorocarbon finishes and stainless hardware options for seaside resorts; aluminum is also termite-free.

FAQ
Questions from Southeast Asian Buyers
Straight answers for developers, contractors and distributors sourcing aluminum windows and doors for the region.
Do you supply aluminum windows and doors to Southeast Asia?
Yes. We supply villas, condominiums, hotels and commercial projects across Thailand, Vietnam, Malaysia, Singapore, Indonesia and the Philippines, shipping factory-direct from Foshan, China via short sea routes to major regional ports.
Are DERCHI windows suitable for typhoon-prone areas?
Our systems can be configured with reinforced mullions, multi-point locking, laminated safety glass and high-performance seals. Our range holds hurricane certification, and our engineers verify wind-load requirements against each project's drawings and location.
Which glass is best for tropical heat?
For most Southeast Asian projects we recommend Low-E insulated glass combined with thermal-break aluminum profiles to reduce solar heat gain and air-conditioning load. Laminated glass is recommended for coastal, high-rise and typhoon-exposed facades.
Do you provide installation support?
Yes. Our 8-step engineering process covers drawing review, R&D, quotation, detail confirmation, on-site measurement, production confirmation and on-site installation guidance.
What certifications do your products hold?
