Curtain wall systems from China are used in commercial, residential, and mixed-use building projects worldwide. The aluminum curtain wall industry in Foshan’s Nanhai district and the wider Pearl River Delta region has developed to a point where Chinese manufacturers can produce unitized and stick-built curtain wall systems that meet the same performance standards as European and North American competitors, at prices that give project developers and architects meaningful budget advantages. Understanding how to specify and source curtain wall from China correctly is increasingly important knowledge for anyone involved in commercial construction procurement.
Types of Curtain Wall Systems Made in China
Stick-built curtain wall, where the aluminum frame is assembled on site from individual horizontal and vertical members, is the most widely produced system and is well suited to projects where a high degree of on-site adjustment is needed. Unitized curtain wall consists of pre-assembled panel units that are installed as complete modules from the inside of the building. This system is preferred for high-rise construction because it reduces on-site installation time and the associated risks of working at height. Structural glazing systems, where the glass is bonded directly to the frame with silicone and no visible frame aluminum appears on the exterior, are produced by Chinese factories for projects where a seamless all-glass facade effect is desired.
Thermal Performance and Energy Compliance
Building energy codes in most markets specify minimum thermal performance requirements for curtain wall glazing systems. The key metric is the overall system U-value, which measures how much heat passes through the combined glass and frame assembly. Thermally broken aluminum profiles, low-e coated insulating glass units, and warm-edge spacer bars all contribute to achieving the required U-value. Always ask Chinese curtain wall suppliers to provide a system U-value calculation and test certification that matches the performance requirements of your project’s local building code.
Glass Options and Specifications
Glass for curtain wall systems is typically specified as insulated glass units consisting of two or three glass panes separated by a gas-filled cavity. Low-emissivity coatings, solar control coatings, tinted glass, and laminated safety glass interlayers are all available from glass processors in the Foshan region. Specify glass performance in terms of visible light transmission, solar heat gain coefficient, and U-value to ensure the building performs as designed.
Work with Agent Foshan on Curtain Wall Sourcing
We work with aluminum curtain wall manufacturers in the Foshan area to source glazing systems for commercial and residential building projects. We help clients define specifications, evaluate supplier capability, manage production oversight, and arrange shipping. Contact us with your project drawings and performance requirements for a sourcing proposal.
You are buying an engineered system, not a product
Everything else in this catalogue is a product you can order from a specification. A curtain wall is not. It is a structural façade element designed for one specific building, and it has to resist wind load, accommodate building movement, drain water, break thermal bridges and, in many jurisdictions, contribute to fire compartmentation between floors.
That means the deliverable includes engineering, not just aluminium and glass. Expect the supplier to produce shop drawings, wind load calculations for your building height and location, and details for every junction. If a factory quotes a curtain wall by the square metre from a photograph, they are quoting a cladding kit and someone else will have to do the engineering.
Stick, unitised, and how the choice affects your site
- Stick system. Mullions and transoms shipped as parts and assembled on the building, with glass installed from outside. Cheaper to ship, far more site labour, slower, and needs external access such as scaffolding or cradles.
- Unitised system. Complete storey height panels assembled and glazed in the factory, then craned into place and locked together. More expensive per square metre, far faster on site, better quality control because the seals are made in a factory rather than at height in the wind.
For tall buildings and tight programmes, unitised almost always wins despite the higher unit price, because site labour and access dominate the total cost. For low rise work, stick systems are usually the sensible answer.
Testing is what separates a real supplier
Serious curtain wall systems are tested as assemblies for air permeability, water tightness under static and dynamic pressure, and structural performance under wind load. Some projects also require testing of the fire stopping between floors and, where relevant, seismic movement capability.
Ask for the test reports for the specific system being offered, not for a similar product. For significant projects, project specific mock up testing is commonly required before production is released, and that takes time and money that must be in the programme from the start. Confirm what your building control authority requires, because façade regulation has tightened considerably in several countries and the requirements differ.
Where the cost actually sits
| System | Approx. FOB per square metre |
|---|---|
| Stick system, standard double glazed | USD 90 to 160 |
| Stick system, thermally broken, low E | USD 140 to 240 |
| Unitised, standard | USD 200 to 340 |
| Unitised, high performance | USD 320 to 600 |
| Structural silicone glazed | USD 260 to 500 |
| Spider or point fixed glazing | USD 300 to 700 |
Approximate FOB ranges for the façade elements. Engineering, shop drawings, testing, shipping, crane time and installation are separate and on a real project they are a large proportion of the total.
Installation is the part that goes wrong
A well engineered façade installed badly leaks. The seals, the drainage paths and the tolerances are all designed on the assumption of competent installation, and curtain walling is a specialist trade rather than general construction work.
Decide early who installs. Some Chinese suppliers will send a supervisor to direct a local crew, which is usually the practical middle ground. Others expect you to arrange installation entirely. Either way, agree responsibility for water tightness in writing, because when a façade leaks the argument between the supplier and the installer is predictable and expensive.
What goes wrong
- No engineering. A kit of parts arrives with no calculations and no approved drawings.
- Test reports for a different system than the one supplied.
- Site dimensions taken from drawings rather than a survey of the built structure, so panels do not fit.
- Fire stopping between floors omitted or not detailed, which is a serious compliance failure.
- Glass breakage in transit from inadequate frames, and no spares ordered.
- Sequence mismatch, where panels arrive in the wrong order for the installation programme. Label and load by elevation and floor.
