L100XL
SUNGYE
The L100XL heavy-duty noise-reduction aluminum casement windows are engineered for commercial projects requiring controlled acoustic performance, thermal efficiency, and structural durability. Designed with a multi-chambered thermal break frame and laminated glazing, these windows address the needs of building contractors, architects, and facility managers working on urban developments, hospitality properties, and high-rise structures. Each unit undergoes factory testing according to established industry standards to ensure consistent performance across production batches.

The laminated glazing with PVB interlayer provides 42 dB of sound reduction when tested according to ASTM E413 standards. This level of acoustic attenuation lowers external traffic noise of 75 dB to approximately 33 dB at interior side, supporting quiet interior conditions for office spaces, hotel guest rooms, and residential units located near airports, highways, or dense urban areas.
The PA66 GF25 thermal break profile interrupts heat transfer through the aluminum frame. Combined with the laminated glazing system, the window achieves a U-value of 1.4 W/m²K or lower. This thermal performance contributes to reduced heating and cooling loads in commercial buildings, supporting energy efficiency targets for new construction and renovation projects.
With a wind load resistance rating of 5.0 kPa (Class 9 per GB/T 7106), these casement windows are suitable for installation in high-rise buildings and regions exposed to strong wind conditions. The hidden drainage system with a discharge capacity of 2 L/min, combined with pressure equalization design, helps prevent water ingress during heavy rainfall events.
The 6-point multi-point locking system and stainless steel hinges provide resistance against forced entry, meeting EN 1627 Class RC2 security standards. This security level is appropriate for ground-floor commercial spaces, residential buildings, and mixed-use developments where building security is a specified requirement.
The frame is extruded from aluminum alloy and features a PA66 GF25 thermal break strip. This polyamide strip with 25% glass fiber reinforcement separates the interior and exterior aluminum profiles, reducing conductive heat transfer while maintaining structural rigidity. The multi-chambered frame design adds further structural stability and improves overall insulation performance.
The standard glazing consists of 5 mm glass + 12 mm PVB interlayer + 5 mm glass. The PVB interlayer holds glass fragments in place upon breakage, reducing injury risk and improving security compared to monolithic glass. Triple-glazing configurations are available upon request for projects requiring higher thermal or acoustic performance.
These aluminum casement windows are specified for a range of commercial construction applications. Urban hotel developments use them to meet guest room noise criteria. High-rise residential towers select them for wind load compliance and unobstructed views. Hospital and healthcare facilities specify them for patient room acoustic comfort. Coastal projects can be configured with enhanced corrosion-resistant coatings to address salt spray exposure conditions.
Project-specific customization is available for commercial procurement orders. Frame finishes include anodized surfaces and powder coating in standard or custom RAL color codes. Glazing can be specified with different thicknesses, tinted options, or low-e coatings based on project requirements. Hardware brands and handle styles can be selected to match project specifications. Custom sash dimensions are available within the maximum size limits, and fixed-light combinations can be designed for large facade openings.
The L100XL series is manufactured under ISO 14001 certified environmental management systems and carries CE marking for compliance with European safety, health, and environmental protection requirements. Acoustic performance is tested according to ASTM E413 standards, and wind load performance follows ASTM E330 test methods. Security hardware meets EN 1627 Class RC2 specifications. Each production batch undergoes factory quality inspection before shipment.
Standard production lead time is 25-35 days for confirmed orders, depending on order volume and customization requirements. Project-specific timelines can be discussed during the quotation phase.
Yes, custom dimensions are available within the maximum sash size limits of 1200 mm width × 2400 mm height. Combined configurations with fixed panels can be designed to fit specific opening sizes.
The 10-year hardware warranty covers manufacturing defects in locking mechanisms, hinges, and operating components. The 20-year glass seal warranty covers seal failure resulting in fogging between glass panes. Warranty terms are detailed in the product documentation provided with each shipment.
Technical installation manuals are provided with all orders. For large commercial projects, remote technical consultation and on-site guidance can be arranged as part of the project support package.
