Stop Treating 4SG Glass as One Price
When you request a price for 4SG glass per square meter, you're missing the most critical detail of the quotation. For building envelopes, an insulating glass unit (IGU) is not a single raw material; it's a sophisticated assembly of multiple glass panes, separated by effective support and sealed around the glass layer to form a dry gas space. Therefore, for 4SG glass, Facade Glass, and Curtain Wall Glass, pricing should prioritize the precise configuration before considering a simple unit price.
Why a Unit Price Can Hide the Real Specification
A quotation genuinely becomes useful only when both parties are discussing the identical glass configuration. Yaohua Glass lists insulated glass, double glazing glass, and facade glass with glass thickness ranging from 3–19 mm. Spacer thickness options include 6A, 9A, 12A, 16A, and 24A, while spacer materials encompass aluminum, stainless, warm edge, TPS, and 4SG.
These extensive options clearly show why two seemingly similar 4SG glass quotations might actually refer to vastly different products. One offer may include a different pane thickness, spacer thickness, glass option, or processing requirement. Alternatively, one might be designed for a specific application, such as windows, sun rooms, skyroofs, or Curtain Wall Glass. Without a comprehensive specification, a lower price might not even meet your actual facade glass requirements.
The Configuration Details That Change the Quote
For procurement teams, the fundamental question isn't merely 'What's the cost of 4SG glass?' but rather, 'Which specific IGU configuration is truly needed?' Yaohua Glass offers Low-E tempered glass, ultra-clear glass, tinted glass, and solar-reflective glass as primary glass options. Processing options include structure sealant, air gas, and 90% argon gas.
| Specification item | Documented options |
|---|---|
| Glass thickness | 3–19 mm |
| Spacer thickness | 6A, 9A, 12A, 16A, 24A |
| Spacer material | Aluminum, stainless, warm edge, TPS, 4SG |
| Glass options | Low-E tempered, ultra-clear, tinted, solar-reflective |
| Processing | Structure sealant, air gas, 90% argon gas |
| Size range | Min. 200 × 300 mm, max. 3300 × 13000 mm, custom sizes |
This table also clarifies why facade glass buyers should avoid comparing products based solely on their names. A thorough 4SG glass inquiry must specify the pane structure, spacer selection, gas processing, panel dimensions, and intended application. Once these critical details are established, comparing quotations becomes far more straightforward.
Production Line Configuration Should Not Be Ignored
For international facade glass projects, evaluating quotations demands attention to production and packing specifics, not just the per-square-meter cost. Yaohua Glass utilizes Bystronic and Lisec insulated glass production lines for its insulated glass products. For buyers assessing Insulated Glass Unit quotations, this is important because curtain wall glass is typically ordered to exact project dimensions and configurations.
Inspection and packing protocols are equally vital to this discussion. Yaohua Glass states 100% inspection before packing for facade glass and uses seaworthy strong wooden crates. Its curtain wall glass packing process describes glass sheets separated by protective materials, inspection before packing, durable seaworthy plywood crates with foam protection inside, and crates fastened by metal belts.
While an initial low 4SG glass price can seem appealing, buyers absolutely need to verify if the quoted facade glass aligns with the required size, spacer type, gas fill, structural sealant, inspection standards, and packing conditions.
A Better RFQ Checklist for 4SG Glass Buyers
A meticulously prepared Request for Quotation (RFQ) empowers a curtain wall glass supplier in China to understand your project clearly, significantly reducing back-and-forth during the pricing process. Instead of simply providing a target unit price, buyers should compile the following essential details:
- Full glass make-up and thickness of each pane
- Exact panel dimensions and quantities
- Spacer material, including 4SG where required
- Spacer thickness: 6A, 9A, 12A, 16A, or 24A
- Required glass option, such as Low-E tempered, ultra-clear, tinted, or solar-reflective glass
- Air gas or 90% argon gas processing
- Structure sealant requirement
- Application, such as curtain wall, window, sun room, or skyroof
- Required quality standard, such as CE EN, ISO9001, SGCC, IGCC, Australia Standard, CCC, or Yaohua internal control standard SDYH-ZY-PZ-03
- Packing requirement for overseas shipment
This comprehensive checklist is also invaluable when comparing a curtain wall glass factory in China with other architectural glass sourcing options, including searches related to a China laminated glass factory, China laminated glass supplier, China toughened glass factory, or China toughened glass supplier. The fundamental principle remains: always confirm that the quoted curtain wall glass precisely matches your project's actual specifications.
Where Yaohua Glass Fits the Procurement Question
Shandong Yaohua Glass Co., Ltd. offers a comprehensive range of insulated glass, double glazing glass, facade glass, and curtain wall glass, all with customizable options for thickness, spacer type, glass options, processing, size, quality standards, and packing details. Its insulated glass units can incorporate clear, tinted, reflective, laminated, or tempered glass, among other options, to meet specific customer requirements detailed in its product documentation.
For those evaluating 4SG glass, the most effective next step is to submit a comprehensive technical request, rather than a singular price inquiry. A truly meaningful quotation will first define the complete unit: encompassing glass thickness, spacer thickness, 4SG requirements, glass option, gas processing, structural sealant, size schedule, quantity, application, relevant standards, and packing specifications.

FAQs
Why is a 4SG glass price per square meter not enough?
Because the final insulating glass unit can vary significantly by pane thickness, spacer thickness, spacer material, glass option, gas processing, structure sealant, size, and application. These details must be fixed before comparing prices to ensure accuracy.
What spacer materials are listed for Yaohua Glass insulated glass?
The listed spacer materials are aluminum, stainless, warm edge, TPS, and 4SG. Spacer thickness options include 6A, 9A, 12A, 16A, and 24A.
What sizes can be specified for facade glass?
Yaohua Glass lists a minimum size of 200 × 300 mm and a maximum size of 3300 × 13000 mm, with custom sizes readily available.
Can argon gas be requested for curtain wall glass?
Yes. The documented processing options include both air gas and 90% argon gas, alongside structure sealant.
What should overseas buyers check besides price?
Overseas buyers should confirm the complete glass configuration, production line information, stringent inspection procedures before packing, robust crate protection, adherence to quality standards, specific application, precise dimensions, and the full quantity schedule.
