Frameless Aluminum Glass Curtain Wall Exterior

Product Overview

Frameless Aluminum Glass Curtain Wall Exterior creates architectural transparency with structural integrity, revolutionizing commercial and high-end residential facades by minimizing visual obstruction while maximizing natural light. Traditional curtain walls compromise between aesthetics and performance—bulky frames reduce glass area, while minimal designs often sacrifice insulation or durability. These innovative systems solve this through 6061-T6 aluminum structural supports paired with ultra-clear tempered glass, achieving near-invisible sightlines with exceptional thermal and wind resistance. Engineered for iconic buildings, they transform exteriors into stunning glass envelopes that reduce artificial lighting needs by 40% while providing superior weather protection and energy efficiency.

Product Features

Minimalist Aesthetics: 12mm-25mm ultra-clear glass (89% light transmittance) with hidden aluminum support structures creates 90% glass-to-frame ratio, maximizing unobstructed views. Custom silk-screen patterns available for solar control or branding.

Structural Performance: 6061-T6 aluminum mullions with 3mm-5mm wall thickness withstand wind loads up to 5kPa (equivalent to 130km/h winds) and seismic forces up to Zone 4 (per ASCE 7). Each support point carries vertical loads up to 12kN.

Thermal Efficiency: Double or triple-glazed units with warm-edge spacers and low-e coatings achieve U-values as low as 1.8 W/(m²·K). Optional thermal breaks reduce condensation risk in cold climates.

Weather Resistance: Multi-stage water management system with EPDM gaskets and pressure-equalized design achieves IP65 ingress protection, preventing water penetration even during driving rain at 150mm/h intensity.

Product Applications

Commercial Towers: Office buildings benefit from increased natural light that boosts occupant productivity by 15% (studies show), while the modern aesthetic enhances property value and tenant appeal.

Luxury Residences: High-rise apartments and penthouses feature floor-to-ceiling glass with unobstructed views, creating spacious interiors with connection to external environments.

Cultural Facilities: Museums, galleries, and auditoriums utilize the glare-reducing glass options to protect exhibits while maintaining visual openness.

Hospitality Buildings: Hotels and resorts create iconic facades that stand out in competitive markets, with the curtain wall system supporting energy-efficient operations.

FAQ

Q: How does the system handle thermal expansion and contraction?

A: The aluminum support structure includes engineered expansion joints that accommodate ±25mm movement per 6m length, preventing glass stress or seal failure during temperature fluctuations from -30°C to 70°C.

Q: What glass options are available for energy efficiency?

A: We offer triple-glazed units with krypton gas fills for cold climates (U-value 1.3 W/(m²·K)) and solar-control low-e coatings for hot regions that reflect 70% of infrared radiation while maintaining visible light transmittance.

Q: Is the system suitable for hurricane-prone areas?

A: Yes, when specified with impact-resistant laminated glass (10mm+1.52PVB+10mm), the system meets Miami-Dade County Product Control 24-05.06 for hurricane resistance up to 150mph winds.

Q: What is the expected lifespan and maintenance requirements?

A: The aluminum structure has a 50-year design life with minimal maintenance—annual inspection of gaskets and drainage paths, and 10-year seal replacement. Glass coatings maintain performance for 20+ years.
