The External Window 118 features an ultra-wide thermal break, a robust 69mm sash, and tilt & turn functionality for superior insulation, structural strength, and versatile ventilation.
Description
External Window 118: Customized, Ultra-Wide Thermal Break Structure
Our external window 118 series begins with a core innovation: a customized ultra-wide thermal break structure. Specifically, this design aligns all thermal breaks and pressure-equalizing seals vertically. Consequently, it achieves superior thermal insulation and outstanding soundproofing. The system utilizes a large 30mm one-piece multi-cavity thermal break alongside a continuous one-piece equal-pressure rubber strip and a 29mm thermal break. Together, these components create an exceptionally tight thermal barrier.
Engineered for High-Performance Experience
Furthermore, this external window 118 delivers a high-performance experience for ultimate comfort. It features super-large 27A insulating glass for excellent energy efficiency. Additionally, a closed opening and press line design ensures a clean finish. A hidden drainage system manages water effectively, while a one-piece vulcanized welding rubber strip guarantees long-lasting air and water tightness.
The Complete High-Performance System
Essentially, this external window 118 is a true high-performance system window. It integrates insulation, soundproofing, wind pressure resistance, and air/water tightness into one unit. Key elements include an ultra-thick 69mm glass fan, a vertical isotherm line, one-piece formed thermal insulation strips, and a flush design both inside and out for a sleek appearance.
Robust Structural Integrity
Critically, the structure ensures rock-solid stability. It employs a built-in integrated expansion glue injection corner code. This process securely connects the frame and sash, minimizing gaps and greatly enhancing torsional resistance. Therefore, the external window 118’s overall wind load performance and sealing capability improve dramatically. Moreover, the super strong mid-fran craftsmanship further increases the entire frame’s wind pressure resistance. Installing a reinforced mullion with a T-shaped corner code connects the beams, tripling the anti-wind pressure performance.
Versatile Tilt & Turn Functionality
Finally, this robust platform can be configured as a sophisticated tilt and turn window. This provides flexible ventilation: it tilts inwards from the top for secure, draft-free airing and turns inwards fully for easy cleaning or maximum airflow, seamlessly integrating with the system’s high-performance features.
External Window 118: Summary of Integrated Excellence
In summary, the external window 118 combines a wide thermal break, superior components, systematic engineering, and reinforced structure into a versatile, high-performance solution designed for modern architectural demands in comfort, durability, and efficiency.
