helps you design insulated windows and double insulated windows that meet both building codes and user expectations.
At Shandong Yaohua Glass Co.,Ltd., we have focused on architectural glass since 1985. As a professional manufacturer, supplier, and exporter, we process tempered, laminated, insulated, Low‑E, frosted, curved, and fire‑resistant glass for diverse building applications.
Main Window Glass Options from Our Factory
Insulated Glass Units for Insulated Windows
Insulated glass units are at the core of most insulated glass windows and double insulated windows. Based on our product specifications, an insulated glass unit is a glass assembly composed of two or more pieces of glass, separated by an effective support and sealed with a binder around the edges to form a dry gas space between the panes.
The glass components in these insulated units can be:
- Clear glass
- Tinted glass
- Reflective glass
- Laminated glass
- Tempered glass
Our insulated units are mainly used for:
- Skyroofs and insulated skylights
- Sun rooms
- Curtain walls
- Windows
Key benefits of these insulated units and insulated glass windows include:
- Greater thermal insulation and energy efficiency
- Reduced room condensation
- Reduced sound transmission from outside
- Attractive aesthetics with increased light and view
- Improved comfort of the building
These advantages explain why insulated glass windows and double insulated windows are widely adopted in energy‑conscious building envelopes.
Window Tempered Glass for Safety Glazing
Window tempered glass is one of our core product categories. In our catalog, it appears in several dedicated series, including:
- Window tempered glass / Window Safety Glass
- Door tempered glass
- Skylight tempered glass
- Curtain wall tempered glass
- Tempered glass fence panels and partitions
These window tempered glass products are used in residential and commercial windows, doors, shower enclosures, glass partitions, pool fence barriers, and glass curtain wall systems. Where projects require safety glass inside insulated glass windows, window tempered glass panes can be built into insulated units to create durable, safer double insulated windows.
Laminated Glass Ranges
Laminated glass is another major processing line at our facility. Our laminated glass catalog covers:
- Laminated glass
- Tempered laminated glass
- Laminated and tempered glass
- Curved laminated glass
These laminated make‑ups can be used on their own or combined inside insulated units when project specifications call for laminated safety performance together with the energy benefits of insulated glass windows.
Low‑E Glass and 4SG Systems
We also provide advanced solutions that enhance insulated units and insulated windows:
- Low‑E glass – used with insulated glass to achieve superior thermal control
- 4SG insulated glass and 4SG curtain wall glass – utilizing warm‑edge style spacer systems in double glazing and curtain walls
These options allow designers to tune the performance of insulated glass windows and double insulated windows for different façade concepts and climate conditions.
How Insulated Units are Built and Specified
Because insulated units sit at the center of modern insulated windows, understanding their construction makes it easier to communicate with us as your China curtain wall glass factory and specify the right configuration.
Glass Thickness, Types, and Sizes
According to our insulated glass unit specifications, the main parameters include:
- Glass thickness: 3–19 mm
- Glass options: Low‑E tempered glass, ultra clear glass, tinted glass, solar reflective glass, and other cataloged types
- Minimum size: 200 × 300 mm
- Maximum size: 3300 × 13000 mm
- Size: Custom sizes supported within this range
This capacity covers standard insulated glass windows as well as large double glazed units for curtain walls and jumbo glass applications.
Spacers and Gas Filling in Insulated Units
The spacer between glass panes has a strong impact on the thermal and condensation performance of insulated units and insulated windows.
- Spacer thickness options: 6A, 9A, 12A, 16A, 24A, etc.
- Spacer materials: Aluminum, Stainless steel, Warm edge systems, TPS, 4SG
Gas filling options inside the sealed cavity of insulated units include Air gas and 90% argon gas. Together with suitable structure sealant, these combinations create reliable insulated units for insulated glass windows, double insulated windows, skyroofs, sun rooms, and curtain walls.
Our production of insulated units is supported by advanced Bystronic and Lisec insulated glass production lines. We also support precise cutting, drilling, and edging to match your exact project drawings.
Quality and Standards
Our insulated glass products strictly follow recognized international and internal standards, including:
- CE EN
- ISO9001
- SGCC (US & Canada)
- IGCC
- Australia Standard (AS/NZS)
- CCC
- Internal control standard SDYH‑ZY‑PZ‑03
These certifications help overseas buyers confidently evaluate our insulated glass windows, insulated units, and window tempered glass from a technical and compliance perspective.
Matching Glass Types to Typical Window Applications
In real projects, you usually combine several glass types inside one insulating system instead of selecting only a single material. Typical configurations based on our product scope include:
Tempered Glass Inside Insulated Glass Windows
For many window openings, a window tempered glass pane is specified where safety glazing is required. That pane can then be combined into insulated units, giving you insulated glass windows or double insulated windows that address both safety and thermal performance. Typical uses include residential and commercial window bands, shopfronts, and doors integrated with window systems.
Laminated and Tempered Glass in Insulated Units
Where laminated constructions are required, buyers often choose laminated and tempered glass or tempered laminated glass from our catalog, then assemble them as one side of the insulated units. This approach is common in glass railing zones adjacent to windows and façade areas requiring laminated safety performance.
Low‑E and 4SG Options for Curtain Walls
On high‑performance curtain walls, insulated glass windows are frequently combined with Low‑E glass as one pane within the insulated units, and 4SG or other warm‑edge spacers for long‑term edge stability. These combinations align with product types such as our 4SG insulated glass and 4SG curtain wall glass.
Practical Specification Checklist for Buyers
When you request quotations for window tempered glass, insulated units, or full insulated glass windows from us, providing clear technical information shortens communication and ensures accuracy.
1. Define the Application and Design Goal
Clarify where the glass will be installed (windows, curtain walls, skylights, or sun rooms) and state your main priorities, whether it's energy‑saving insulated windows, better noise reduction, or safety focus using window tempered glass.
2. Decide Between Single Glazing and Insulated Windows
Determine if the opening should use single window tempered glass or insulated units as the base for insulated glass windows and double insulated windows.
3. Confirm Glass Types and Thickness
Choose a glass thickness between 3–19 mm for each pane, and select from Low‑E, ultra clear, tinted, or solar reflective glass.
4. Specify Spacer, Cavity, and Gas for Insulated Units
Fine‑tune your insulated windows by choosing spacer thickness (6A to 24A), spacer material (aluminum, warm edge, 4SG), and gas filling (air or 90% argon gas).
