BLOSSOM CHEER Aluminum Windows: 5-Performance Certified for Projects
Industry-leading wind/water/air/thermal/acoustic test reports. Custom heavy-duty aluminum windows for developers, contractors & wholesalers.
| Performance | Our Rating | Real-World Impact | What It Means for You | Industry Benchmark |
| Wind Resistance | Level 9 ★ | Withstands 3,500Pa pressure ≈ 200km/h typhoons. No deformation or blowouts! | Stands super typhoons (like 200km/h winds!) | Standard: Level 6-8 |
| Airtightness | Level 8 ★ | < 0.5m³/(m²·h) air leakage → Stops energy leaks & dust ingress | Zero drafts = lower HVAC costs | Standard: Level 4-6 |
| Water Tightness | Level 3 | Zero penetration under 700Pa rain simulation (torrential downpour scenario) | No leaks during heavy storms | Standard: Level 1-2 |
Thermal Insulation | Level 4 | U-value = 1.8 W/(m²·K) → 30% lower HVAC costs vs. basic windows | Saves 30%+ energy vs. standard windows | Standard: Level 2-3 |
Sound Insulation | Level 2 | Rw 30dB → Cuts traffic noise noticeably (Ideal for urban residences) | Clear noise reduction for urban projects | Standard: Level 1 |
(Testing standard: GB/T 8478-2020 / ISO 18091)
Why This Matters for You
For Developers
"Level 9 wind resistance isn’t just specs – it’s insurance against warranty claims. One window failure in a storm could cost millions."
Our clients (like Sino-Ocean Group) use these certifications to:
● Secure building permits faster
● Achieve green building credits (LEED/ BREEAM)
● Market "storm-proof residences" at premium prices
For Contractors & Wholesalers
"Level 8 airtightness = no callback headaches. Drafty windows are the #1 post-install complaint."
✅ Pre-tested system designs (No on-site surprises)
✅ Custom sizing & hardware pre-machining (Accelerate installation)
✅ Bulk packaging (Save site handling costs)
We custom-engineer every window for YOUR project specs. Architects and developers choose us because:
✅ Test-Backed Reliability (GB/T 8478-2020 certified)
✅ Bulk Order Savings (MOQ 50+ units)
✅ 15-Day Lead Time Guarantee
