Lucky A5 Soundproof Aluminum Casement Windows Delivered for 240-Unit Luxury Urban Apartment Complex
Project Overview: 240-Unit Urban Luxury Apartment Tower — Bangkok, Thailand
Client: A leading Southeast Asian real estate developer specializing in premium high-rise residential projects.
Project Scale: 240 residential units across 32 floors, requiring approximately 1,850 aluminum casement window units.
Challenge: The development is situated in a high-traffic urban corridor facing dual challenges: persistent street noise exceeding 75 dB during peak hours and strict municipal energy efficiency mandates requiring superior thermal insulation performance.
Solution: Lucky A5 Soundproof Thermal Break Aluminum Casement Window Series
After evaluating multiple suppliers, the developer selected Lucky's A5-110 Soundproof Aluminum Casement Window with Thermal Break and Multi-Point Locking system. Key specifications deployed across the project:
| Specification | Detail |
|---|---|
| Model | A5-110 Thermal Break Casement Window |
| Profile | 1.8-2.0mm aluminum thickness with PA66 polyamide thermal break |
| Frame Depth | 110mm |
| Glass | 5mm+20A+5mm double tempered glass with argon gas (PVDF aluminum spacer) |
| Hardware | inke 15-inch stainless steel friction stays + inke black handles |
| Security | Multi-point cam locking system with anti-fall rope (150KG capacity) |
| Opening | Outward opening / awning configuration |
| Sealing | Continuous EPDM rubber gaskets (automotive-grade) |
Project Execution & Results
- Noise Reduction Performance: Independent acoustic testing confirmed a 38 dB reduction in external noise transmission, bringing interior sound levels well below the 35 dB threshold required for premium residential certification. Residents reported significantly quieter living environments despite the building's downtown location.
- Thermal Efficiency: The PA66 polyamide thermal break combined with argon-filled double glazing reduced HVAC energy consumption by an estimated 22% compared to the developer's previous non-thermal-break specifications, contributing directly to the building's green certification goals.
- Child Safety Compliance: The standard stainless steel anti-fall rope (150KG bearing capacity) met all local safety codes for high-rise residential buildings, providing peace of mind for families with young children.
- Supply Chain Reliability: Lucky delivered the full 1,850-unit order in three phased shipments over 10 weeks, with zero quality rejections at the installation site. The 10 sqm MOQ allowed the developer to run a successful 50-unit pilot installation prior to full-scale deployment.
- Installation Efficiency: Standardized opening panel dimensions (400-850mm width, 400-1600mm height) and pre-assembled hardware enabled the local installation team to complete an average of 28 units per day, accelerating the overall construction timeline by approximately 3 weeks.
Client Feedback
The project developer has since specified Lucky aluminum casement windows as the preferred fenestration system for two additional pipeline projects totaling over 500 units, citing consistent product quality, competitive factory-direct pricing, and responsive 24/7 B2B service support as decisive factors.
