Thermal Break Aluminum Circular Roof Window
Description
Reviews
Circular Roof Window — Precision Engineered for Premium Architecture
Combining high-performance materials with intelligent control systems, ideal for daylighting and natural ventilation in high-end residential and commercial buildings.
Fabricated from thermal break aluminum alloy using laser seamless welding, with an electrostatic powder coating or PVDF fluorocarbon finish. The hidden chain or dual-screw motor drive ensures a clean profile when closed, while the integrated rain sensor and smart control system deliver effortless automation.
Core Innovation
GRPU composite technology, triple-tested sealing, and hidden smart actuation — engineered for decades of performance.
GRPU Composite Frame
Core material: GRPU (Glass-Fiber Reinforced Polyurethane) with 80% fiberglass content, delivering extremely low thermal conductivity and outstanding load-bearing strength — the internationally recognised premium choice for window frames.
Laminated Insulating Glass
Standard configuration: insulated laminated tempered safety glass, combining sound insulation, thermal insulation, and condensation prevention. EPDM seals remain elastic down to –15 °C for long-term weather resistance.
Waterproof Drainage System
Structural waterproofing principle (seal + active drainage) with multiple wind-and-water barrier channels and a dedicated drainage pathway, ensuring a permanently dry interior in all weather conditions.
Key Selling Points
Why specifiers and homeowners choose our skylight systems — proven performance backed by rigorous certification.
Superior Thermal Performance
GRPU is recognised internationally as the top-tier frame material, offering a thermal conductivity far lower than standard aluminium, directly translating to reduced heating and cooling loads.
Proven Weathering Resistance
Passed 1,080 hours of salt spray testing and 1,000 hours of UV resistance testing — guaranteeing no fading or degradation over years of outdoor exposure. Built to endure.
Maximum Safety — Triple Glass
The triple laminated glass configuration provides exceptional resistance to impact and shattering. Even if broken, the PVB interlayer holds fragments in place — protecting occupants below at all times.
