Aluminum Alloy Double Hung Casement Windows

55 Series Thermal Break Hollow Double Glass Aluminum Window – Superior Insulation, Soundproofing & Energy Efficiency for Modern Living

The 55 Thermal Break Hollow Double Glass Series is a premium aluminum window system engineered for high-performance residential and commercial applications. Designed with advanced broken bridge technology and double-pane insulating glass, this window delivers exceptional thermal resistance, acoustic dampening, weatherproofing, and long-term energy savings—ideal for modern buildings that prioritize comfort, sustainability, and aesthetic appeal.

Key features include a thermally broken aluminum frame made from high-strength extruded alloy, integrated with durable nylon or polyester insulation strips to minimize heat transfer between indoor and outdoor environments. The double-glazed unit typically consists of two 5mm glass panes separated by a 12mm air gap filled with argon gas—a proven method to enhance both thermal and sound insulation performance. This configuration significantly reduces condensation, noise infiltration, and energy loss, making it perfect for urban homes, luxury apartments, and office spaces in climate-sensitive regions.

This casement-style window offers smooth operation, excellent ventilation control, and a sleek, minimalist profile that complements contemporary architecture. Its robust construction ensures strong wind load resistance, while the precision engineering supports reliable sealing against rain, dust, and pollutants—critical for high-rise installations and coastal properties. The surface finish resists corrosion, fading, and wear, ensuring low maintenance over decades of use without sacrificing visual elegance.

Perfectly suited for upscale housing developments, boutique hotels, executive offices, and eco-conscious villas, the 55 series excels in environments where occupant comfort, environmental responsibility, and architectural harmony are paramount. Whether installed in new builds or as part of a renovation project, this window system enhances indoor air quality, reduces HVAC costs, and contributes to green building certifications like LEED or BREEAM.

Users consistently praise its quiet interior environment, especially in busy city centers or near airports and highways. Many note how the improved thermal barrier maintains consistent room temperatures year-round, eliminating drafts and reducing reliance on heating or cooling systems. Homeowners appreciate the clean lines and customizable options—such as color finishes, hardware styles, and optional security locks—that allow seamless integration into diverse design schemes.

Common questions often revolve around installation ease and long-term durability. Unlike traditional windows, the 55 series is designed for straightforward mounting across various wall types—including concrete, brick, and timber frames—minimizing labor time and disruption during construction. Maintenance is minimal: regular cleaning with mild detergent and water keeps the frame looking new, while periodic checks on seals and hinges ensure optimal function. With proper care, these windows can last 20–30 years or more, offering outstanding value for money compared to standard aluminum or uPVC alternatives.
