Product Description
Factory Direct: Cut-to-Size Low-E Insulated Glass for Windows & Facades
We specialize in supplying high-volume, custom-sized Low-E Hollow Glass (Insulated Glass Units) for window fabricators and building contractors. By combining high-quality Soft-Coat Low-E glass with automatic Argon Gas Filling, we deliver double glazing units that meet modern energy codes at a competitive wholesale price.
Why Choose Our Basic Custom Series?
Cut-to-Size Precision: We produce exact dimensions based on your window schedule or CAD drawings, ready for immediate installation.
Argon Gas Filled: We fill units with 90%+ Argon gas as a standard feature to improve thermal insulation (U-Value) and soundproofing.
Fast Turnaround: Optimized production lines for standard 5mm+12A+5mm and 6mm+12A+6mm configurations ensure quick delivery for your projects.

Production Process
Automatic removal of the coating at the edge to guarantee strong sealant adhesion.
The glass and spacer are assembled and pressed in a gas-filling plate press, achieving 90%+ Argon gas concentration
Automatic sealing robot applies the final Structural Silicone (or Polysulfide) layer to guarantee structural integrity

Testing Quality
We strictly control the quality to prevent after-sales headaches:
Dew Point Test: Ensuring the dew point is below -40°C, so no fogging occurs inside the glass even in freezing winters.
Sealant Adhesion: Butterfly test to check the mixing ratio and stickiness of the structural silicone.
Gas Retention: Regular checks to confirm Argon gas leakage rate meets international standards (EN 1279).
