Product Description
High-Performance Double Glazed Insulated Glass Panels
Our Insulated Glass Panels (also known as Double Glazing or IGU) are the standard solution for modern energy-efficient windows. Manufactured by sealing two panes of glass with a durable aluminum spacer, these panels create a thermal barrier that significantly reduces heat loss and noise transmission.
Why Choose Our Insulated Glass?
Standard Specifications: We specialize in mass production of the most popular configurations: 5mm+12A+5mm and 6mm+12A+6mm, ensuring fast delivery and consistent quality.
Energy Efficiency: The hermetically sealed air space (12mm Air/Argon) acts as an insulator, keeping interiors cooler in summer and warmer in winter.
Moisture Free: Filled with high-quality desiccant to prevent internal fogging and condensation, backed by a 10-year warranty.

Comment & FAQ
Q1: Can I customize the spacer thickness?
A: Yes, while 12A (12mm) is the most common standard, we also offer 6A, 9A, 16A, and 20A spacers to fit your window frame channel.
Q2: Is your insulated glass filled with Argon?
A: Standard units are filled with dry air. We can upgrade to Argon Gas upon request for improved thermal performance (U-Value).
Q3: What is the lead time for 5mm+12A+5mm panels?
A: For standard specifications like this, our automated lines allow for a very fast production time, typically 7-10 days for container orders.

Data Sheet
| Parameters | Property | Value / Example | Description |
| Thermal Performance | U-value (W/(m²·K)) | Standard DGU: 2.8~3.2 | Lower value indicates better insulation |
| Low-E DGU: 1.6~2.0 | |||
| Argon Filling: 1.0~0.3 | |||
| SHGC (Solar Heat Gain Coeff.) | Clear Glass: 0.7~0.8 | Lower value reduces solar heat gain | |
| Low-E Glass: 0.25~0.40 | |||
| Visible Light Transmittance (VLT) | Clear Glass: 85%~90% | Affects indoor lighting brightness | |
| Low-E Glass: 70%~80% | |||
| Frosted Glass: 50%~60% | |||
| Visible Light Reflectance (VLR) | Standard Glass: 8%~12% | Higher reflection reduces glare | |
| Low-E Glass: 15%~25% | |||
| Acoustics | Rw (Weighted Sound Reduction Index, dB) | 6mm Monolithic: 31 | Higher value indicates better sound insulation |
