It features multiple modern production workshops, including melting and casting, extrusion, spraying, oxidation, digital door and window systems, and intelligent processing, as well as finished product warehouses and a professional design and R&D center.
The company serves both domestic and international markets. Supply Wholesale JZ-JF108 Inward Casement Window. By participating in global exhibitions such as the Canton Fair, it continues to expand its overseas presence, with products exported to major countries and regions worldwide. It has been recognized as a national high-tech enterprise and a “Little Giant” enterprise for specialization, refinement, and innovation.
The JZ-JF108 Inward Casement Window is engineered for modern residential and commercial projects that demand both efficient use of interior space and strong building envelope performance. With a profile system reaching the 108mm class, the window opens outward from the sash while the operable panel swings inward toward the frame line, freeing up usable indoor floor area. This design is particularly well suited to balconies, bay windows, and compact interior layouts where every square meter counts.
In terms of core dimensions, the visible interior frame width measures 40mm, striking a balance between generous daylight transmission and structural rigidity. The overall profile width is 106mm for the frame and 64mm for the sash, a combination that provides a stable frame-and-sash structure capable of supporting substantial hardware loads while leaving sufficient material depth for multi-stage sealing.
The aluminum itself is produced to a national-standard wall thickness of 1.8mm, ensuring the profile resists deformation under repeated opening and closing cycles as well as wind loading over the long term. The raw material is Huilv's own 6063-T5 virgin aluminum alloy, a grade widely recognized in the architectural window and door industry for its favorable combination of strength, toughness, and workability, allowing the profile to remain lightweight without sacrificing structural stability. Thermal performance is delivered through branded PA66-GF25 thermal break strips, a glass-fiber-reinforced nylon material known for excellent insulation continuity and long-term resistance to aging, forming one of the core components behind the window's insulation and energy-saving performance. Surface finishing is available in either powder coating or fluorocarbon spray painting, with customizable color options, giving specifiers the flexibility to match a wide range of façade aesthetics while maintaining weather resistance across different climate conditions.
The opening configuration pairs an inward-opening glass sash with an outward-opening screen sash, supporting ventilation and insect protection simultaneously while keeping both panels easy to clean and maintain. Hardware is fitted with Chinese-brand components as standard, with alternative hardware specifications available on request to accommodate different regional procurement preferences and project budgets. The glazing package consists of 6mm Low-E glass, a 12mm argon-filled cavity, and 6mm tempered glass, delivering strong thermal insulation, sound reduction, and impact safety in a single unit; the argon fill can be adjusted according to project requirements to further enhance thermal performance. The insulating glass spacer uses a one-piece bent black aluminum bar filled with molecular sieve desiccant, which effectively absorbs moisture inside the cavity to reduce fogging and condensation, with the specification adjustable to suit different project needs.
On the sealing and structural side, the series uses EPDM rubber gasket seals combined with a flush isothermal line design to achieve a three-stage sealing system, significantly improving the window's airtightness, watertightness, and acoustic insulation — the technical foundation behind its strong waterproofing and sound-blocking performance. Corner assembly relies on expansion-type high-strength aluminum corner keys paired with stainless steel reinforcement plates, with sealant applied at the joints followed by two-component injection sealing, ensuring each corner connection remains tight and secure over time without loosening or water infiltration. The drainage system uses a concealed drainage structure that maintains smooth water evacuation while preserving a clean, uninterrupted exterior appearance. All four corners of the window also feature a safety R-corner design, reducing the risk of sharp-edge injury while reflecting attention to manufacturing detail.
Taken together, the JZ-JF108 Inward Casement Window reflects a systematic approach across material selection, thermal and acoustic structure, and sealing and corner assembly craftsmanship, offering a dependable window solution for residential and commercial construction and representing Huilv's technical accumulation in the architectural aluminum window and door sector.
