Double Glazed Insulating Glass

Double glazed insulating glass is our most widely used insulating glass product. Two glass panes are separated by an aluminum spacer and sealed. Dry air or inert gas fills the cavity. This structure reduces heat conduction and radiation through glass. It provides basic energy-saving insulation. Maximum size reaches 2800mm × 5500mm. Thickness combinations are flexible. We can customize based on your window profiles and energy requirements. Applications include residential windows, office curtain walls, school windows, hospital exterior windows, and commercial building enclosures. Double glazed insulating glass solves basic building energy efficiency needs.

We use an automated insulating glass production line. Equipment includes a spacer bending machine, molecular sieve filling machine, automatic sealant applicator, and argon filling machine. Molecular sieve desiccant inside the spacer keeps the cavity dry. This prevents fogging and condensation. Every double glazed insulating glass panel undergoes 100% inspection before shipping. Our quality team checks seal performance, appearance quality, and dimensional accuracy. Third-party inspections are welcome. Our insulating glass passes dew point testing and meets GB/T 11944 standards.

We support OEM and ODM customization. We configure to your profile and energy requirements. Double glazed insulating glass production takes 10 to 15 working days. Export packaging uses fumigated wooden crates. EVA foam separates each glass sheet. Corner protectors guard edges. Waterproof wrapping covers the shipment. We offer EXW, FOB, and DDP trade terms. Double glazed insulating glass comes with a 2-year warranty. Our after-sales team provides 24-hour support. We supplied 8,000 square meters for Suzhou Industrial Park and 12,000 square meters for a Zhejiang residential project.
