Explore our export-certified architectural window series, precision-manufactured with heavy-duty extrusions, Lodz-366 thermal glazing, and corrosion-resistant hardware for commercial and residential developments across Vietnam.
A comprehensive analysis of thermal efficiency, acoustic insulation, and monsoon moisture management for project developers, architects, and main contractors in Vietnam.
Vietnam’s intense solar irradiance demands advanced Solar Heat Gain Coefficient (SHGC) control. Our hopper windows incorporate Lodz-366 triple-silver low-E glazing combined with argon gas insulation, blocking up to 95% of destructive ultraviolet rays while dramatically cutting air conditioning loads in Ho Chi Minh City and Hanoi high-rises.
During Vietnam's severe rainy seasons and typhoon events, window joint leakage is a primary point of building envelope failure. Our hopper window profiles feature fusion-welded frame corners and continuous multi-tier EPDM weather-stripping engineered to withstand driving rain up to 720 Pa (DP65), eliminating moisture infiltration completely.
Urban density in metropolitan hubs like Hanoi, Da Nang, and Ho Chi Minh City results in pervasive ambient noise pollution. Utilizing asymmetric dual-pane acoustic glass units (e.g., 6mm + 12Ar + 8mm laminated), our hopper window assemblies deliver Sound Transmission Class (STC) ratings exceeding 42dB for peaceful interiors.
From high-density apartment blocks to coastal luxury resorts and industrial parks, discover how our custom-manufactured hopper fenestration systems fulfill localized functional requirements.
Space optimization is critical in residential tower complexes across Hanoi and HCMC. Installed at ceiling height, compact vinyl hopper windows provide permanent privacy while permitting continuous moisture venting. Inward tilting prevents exterior projection conflicts with narrow building setback lines or exterior façade claddings.
Resort developments in Da Nang, Nha Trang, and Phu Quoc require high resistance to salt-spray corrosion. Our high-grade virgin UPVC profiles and powder-coated T6 thermal break aluminum frames are certified zero-corrosion under ASTM B117 salt spray testing for over 3,000 hours, keeping luxury coastal properties free from frame degradation.
In industrial hubs such as Binh Duong, Dong Nai, and Bac Ninh, factory administrative complexes demand robust, low-maintenance passive ventilation. Our heavy-duty commercial hopper windows feature multi-point locking mechanisms and optional motor-actuated motorized operators for automated roof-level heat exhaust system integration.
Energy code compliance (QCVN 09:2017/BXD in Vietnam) mandates strict overall heat transfer coefficient (U-factor) standards. By pairing our thermally broken profile design with warm-edge spacer technology, our windows effortlessly assist developers in securing green building certifications (LEED or LOTUS Vietnam).

Vertical manufacturing control from raw resin extrusion to direct sea container freight consolidation for Vietnamese ports.
We own the extrusion dies and raw resin blending lines. Utilizing 100% virgin vinyl without reground scrap guarantees uniform wall thickness, high impact resistance, and zero structural yellowing under tropical UV stress.
Every window schedule is custom-fabricated in precise 1/8-inch increments. Whether matching existing structural rough openings in retrofits or custom architectural elevations, no site-applied filler strips are required.
Each production lot undergoes 100% corner weld tensile testing, sash alignment checks, multi-point lock engagement verification, and seal pressure tests prior to protective film application and packaging.
Units are individually labeled by floor and opening schedule, wrapped in protective foam, corner-padded, and palletized in heavy-duty wooden crates designed for seamless sea freight discharge at Cat Lai (HCMC) or Haiphong ports.
Backed by our backing guarantee: non-prorated limited lifetime warranty on vinyl extrusions, insulated glass seal integrity, and mechanical hardware systems, offering complete peace of mind to project owners.
Our dedicated engineering department collaborates directly with architectural firms and project managers to formulate tailored fenestration shop drawings, custom extrusion profiles, and specialized hardware specifications.
Clear engineering, logistics, and purchasing answers tailored for developers, hardware importers, and contractors importing to Vietnam.
Standard factory production lead time is typically 15 to 25 business days depending on custom color laminates or special glazing requirements. Direct sea freight container shipping to major Vietnamese ports like Cat Lai (Ho Chi Minh City), Da Nang, or Haiphong takes approximately 10 to 18 transit days.
Our vinyl and aluminum hopper windows are built with heavy-wall extruded profiles reinforced with galvanized steel sub-insert channels. Combined with multi-point perimeter compression locking hardware and sloped exterior weep channels, our windows carry up to DP65 structural wind ratings, staying completely water-tight during heavy monsoon rainstorms.
Aluminum profiles—even when anodized—can suffer from salt-air oxidation and pitting over time in coastal locations like Phu Quoc or Nha Trang. Fusion-welded UPVC is completely chemically inert, unaffected by marine air, acidic rain, or high humidity, and will never pit, peel, or rust while delivering superior thermal insulation.
Yes. Every single unit is manufactured to order in 1/8-inch (3mm) precise custom dimensions based on your window schedule. We also offer combined configuration units such as fixed arched tops with bottom operating hoppers or multi-lite window walls built on the same structural frame platform.
Absolutely. When configured with our double-glazed Lodz-366 argon-filled insulating units (U-Factor ≤ 1.6 W/m²·K, SHGC ≤ 0.25), our window assemblies easily exceed the thermal efficiency mandates laid out in Vietnam’s National Technical Regulation on Energy Efficiency Buildings (QCVN 09:2017/BXD).
We supply full export documentation packages, including Commercial Invoices, Packing Lists with opening mark-numbers, Bills of Lading (B/L), Certificates of Origin (Form E or Form AK for tariff optimization), and certified factory test reports for smooth Vietnam Customs clearance.
