1. Energy Waste from Poor Sealing

Low-quality IGUs lose argon gas fill within 2-3 years, reducing U-value from 1.1 W/m²K to 2.8 W/m²K.

2. Structural Failures

Non-tempered glass in IGUs cracks under temperature swings >60°C, causing leakage and mold.

3. Extended Lead Times

Generic suppliers quote 12-16 weeks for custom IGUs. We deliver in 4-6 weeks with our PVB/EVA laminating lines.

4. Hidden Certification Gaps

Some suppliers skip EN 1279-3 (gas leakage tests) or EN 356 (anti-burglary).

5. Shipping Damage

Thin spacers in inferior IGUs collapse during transit, voiding warranties.

6. Post-Sale Support

Generic suppliers vanish after delivery. We offer 24/7 technical support for your projects.

1. What’s the difference between double and triple-glazed IGUs?

Double-glazed (6+12+6): Two panes with 1.1 W/m²K U-value, ideal for moderate climates. Triple-glazed (6+12+6+12+6): Three panes with 0.5 W/m²K U-value, cutting heating costs by up to 50% in cold regions (source: Fortune Business Insights).

2. Can you customize IGUs for hurricane-prone areas?

Yes! We offer EN 13541-certified laminated insulated glass with EN 12600 impact resistance and EN 356 anti-burglary ratings. Used in Florida and Caribbean projects.

3. What’s your minimum order quantity (MOQ)?

No MOQ for samples or small orders. For bulk orders, MOQ starts at 100 sqm.

4. How do you ensure gas retention in IGUs?

We use:

• Swiss Warm Edge spacers (thermal break)
• Polysulfide + polyurethane dual-seal system
• Helium gas leakage tests on every batch

Result: < 1% gas loss after 10 years (vs. 20-30% in generic IGUs).

5. Do you offer OEM/ODM services?

Absolutely! We provide:

• Custom sizes and shapes
• Branded packaging
• Private labeling
• Design-to-manufacture support

6. What’s your warranty policy?

10-year performance warranty covering:

• Gas leakage
• Condensation issues
• Structural integrity

Fine print: Warranty voids if installed incorrectly or using unapproved sealants.
