Ununinterrupted Views with Precision Engineering
Manufactured by Meric Window Systems Co., Ltd., the JW157 Panoramic Sliding Door system integrates minimalist architectural design with industrial load-bearing performance. Designed for high-end villas, resort facades, and modern commercial spaces.
Six Structural Decisions Behind 6-Metre Span Openings
Large-format glass doors require meticulous structural calculation. Every JW157 extrusion and carriage assembly is built to eliminate deformation and deliver effortless sliding movement.
1. Minimalist Profile Geometry
Where adjacent leaves overlap, the vertical interlock profile measures just 25mm. The outer frame is engineered with a 70mm depth on a robust 2.0mm structural wall, while primary sliding profile walls vary from 3.0mm to 8.0mm thick depending on wind load requirements.
2. Heavy-Duty Self-Levelling Carriage
Panels weighing up to 1,500kg ride on stainless-steel tracks via custom self-levelling roller carriages. Rather than stressing seals or top guides, the structural load is carried entirely along the lower track, permitting smooth one-handed manual operation.
3. Multi-Track Modular Configuration
The bottom track features a 58mm width per channel, configurable from 2 to 6 tracks in single, double, or triple row layouts. This flexibility allows entire exterior walls to open seamlessly into adjacent living zones.
4. Multi-Point Locking & Security
The JW157 features a custom three-point gear locking mechanism paired with a position state indicator, giving building occupants immediate visual confirmation of panel lock status.
5. 43mm Glazing Rebate Capacity
A wide 43mm glass rebate accommodates double or triple laminated insulated glass units (IGU) such as 16mm + 12A + 16mm or 8mm + 12A + 8mm, maximizing sound reduction and thermal insulation values.
6. Optional Automated Motor Drive
For oversized architectural panels or commercial barrier-free access, an integrated concealed motor drive system can be installed inside the upper profile frame for single or multi-leaf synchronized operation.

Eight Reasons to Specify the JW157 System
Designed for seamless performance, long-term durability, and low maintenance under high-traffic and coastal weather exposure.
Panoramic Space Release
Multi-track sashes stack neatly to clear up to 60% of the structural opening width, turning interiors into outdoor living spaces.
Ergonomic Built-in Pull
Integrated profile handle channels eliminate the need for bulky surface-mounted hardware, preserving ultra-narrow sightlines.
Concealed Drainage
Rainwater is routed through internal profile chambers rather than exposed face weep holes, keeping the exterior profile clean.
Thermal Efficiency
Polyamide thermal breaks prevent heat exchange across inner and outer extrusions, meeting modern energy code standards.
Acoustic Isolation
Engineered EPDM perimeter gaskets combine with insulated glass to significantly attenuate urban ambient noise.
Flush Floor Track
Low-profile 58mm tracks can be recessed into finished floor levels for smooth, barrier-free architectural transitions.
Smart Automation
Optional heavy-duty imported motors drive individual or multi-sash configurations via remote control or home automation systems.
90° Postless Corner
Specialized corner joint profile designs allow two sliding elevations to meet and retract without requiring a fixed structural column.
Project Engineering & Export Packaging
Every project manufactured by Meric Window Systems Co., Ltd. undergoes strict quality control before international container dispatch.
Shop Drawings & Structural Verification
Our engineering office prepares full shop drawings showing profile sections, glass build-ups, track anchorage, and structural wind load calculations for architectural sign-off before fabrication begins.
Seaworthy Protective Packaging
Windows and doors are wrapped with protective film, corner foam guards, and strapped into heavy-duty reinforced wooden crates or steel A-frames labelled according to your site window schedule.
Frequently Asked Questions
Technical details and procurement guidance for architects, contractors, and project developers.
A single sash leaf can be fabricated up to 6,000 mm high and 6,000 mm wide, carrying a total weight of up to 1,500 kg supported by heavy-duty self-levelling bottom rollers.
Yes, manual operation remains smooth because the panel weight is distributed onto precision self-levelling carriages along the stainless-steel track. For added convenience or public spaces, an integrated motorized drive system is available.
The JW157 features a 43 mm glass rebate, supporting double or triple laminated insulated glass units up to 16mm + 12A + 16mm or 8mm + 12A + 8mm to meet thermal and acoustic requirements.
Yes, the floor track is engineered for low-profile and fully recessed threshold installations, creating a seamless barrier-free transition between indoor and outdoor living areas.
The system utilizes concealed internal drainage channels inside the structural profile rather than exposed face weep holes, keeping water out while maintaining high air tightness and wind pressure resistance.
