Product Overview
Traditional outward-opening windows pose safety risks in high-rise buildings and consume valuable exterior space, while single-pane designs fail to meet modern insulation standards. These inward-opening windows solve these issues through a thermal break aluminum frame construction paired with high-performance double-glazed units, delivering superior thermal insulation while allowing safe, space-efficient operation. Engineered for versatility, they accommodate diverse architectural styles with customizable sizes, finishes, and configurations, reducing heating/cooling costs by up to 30% in moderate climates.
Product Features
Advanced Thermal Performance: 6063-T5 aluminum frames with 24mm polyamide 66 thermal barriers achieve U-values as low as 1.4 W/(m²·K) (NFRC certified). Double-glazed units (4mm tempered glass + 16mm argon gas fill + 4mm low-e glass) reduce heat transfer by 72% compared to single-pane windows.
Space-Saving Operation: Inward-opening sashes with multi-point locking systems require only 150mm clearance for full operation, ideal for rooms with limited exterior space or adjacent balconies. Optional tilt-in function allows secure ventilation without full opening.
Acoustic Insulation: Multi-chambered frame design combined with laminated inner glass achieves STC ratings of 33-36 dB, reducing urban noise pollution (traffic, construction) by approximately 50% for quieter interiors.
Custom Configuration: Available in sizes from 400mm×600mm to 1800mm×2400mm with top-hung, side-hung, or combined tilt-turn mechanisms. Over 180 RAL powder coat finishes including wood grain options with 15-year color retention warranty.
Product Applications
High-Rise Residences: Safe inward operation eliminates fall risks in apartments above ground floor, while thermal performance reduces condensation on interior surfaces during cold weather.
Historic Renovations: Custom profiles match traditional window designs while upgrading insulation performance, meeting historic preservation requirements in heritage buildings.
Home Offices: Acoustic insulation creates productive work environments in urban settings, while tilt ventilation prevents dust infiltration during air changes.
Healthcare Facilities: Easy-clean surfaces and secure locking mechanisms meet hospital infection control standards, with inward opening facilitating window cleaning from inside patient rooms.
FAQ
Q: Can these windows be fitted with security features?
A: Yes, optional reinforced hinges, anti-lift devices, and laminated security glass (resistant to 9mm impact testing) achieve RC2 security rating, deterring forced entry attempts.
Q: What is the maximum wind load resistance?
A: The reinforced frame design withstands wind loads up to 2.8kPa (equivalent to 120km/h winds) when properly installed, meeting ASTM E330 standards for coastal and high-wind regions.
Q: How does the argon gas fill maintain performance over time?
A: Hermetically sealed units with dual butyl seals retain over 90% of argon gas for 15+ years, maintaining thermal performance. Our windows include a 20-year warranty against seal failure.
