Lift & Fold Series: Folding & Motorised Lift Windows

Architectural Glazing Systems

Engineered for Seamless Indoor-Outdoor Integration

Meric Window Systems Co., Ltd. manufactures 17 distinct models across three specialised architectural window families. Designed for luxury villas, hospitality projects, and modern commercial elevations, our Lift & Fold Series delivers maximum daylight, robust weather resistance, and smooth operating dynamics.

Barrier-Free Flush Tracks

The folding family and select motorised lift models feature threshold-free designs. Tracks integrate directly into finished floor levels, eliminating stumbling hazards while maintaining weather seals.

Counter-Balanced Positioning

Manual lift window sashes incorporate precision internal balancing systems. Heavy sashes remain securely positioned at any height without unintended movement or manual strain.

Triple Safety & Motorised Drive

Automated lift windows operate with quiet rack-and-pinion technology, integrated stainless insect screens, anti-pinch sensors, and emergency child-lock safety controls.

Manufacturing Excellence

Quality Assurance & Export Packaging Standards

At Meric Window Systems Co., Ltd., every window frame and operating mechanism undergoes rigorous pre-shipment quality control to ensure smooth installation and long-term durability in tropical, temperate, or arctic climates.

CNC Precision Milling

Corner joints, hardware recesses, and drainage ports are milled to sub-millimeter tolerances on multi-axis CNC machining centers.

EPDM Double Sealing

Continuous synthetic EPDM weatherstripping guarantees tight air tightness and superior water resistance against driving rain.

Surface Coating Finish

Qualicoat-certified powder coating, fluorocarbon (PVDF), or anodized finishes resist corrosion, UV degradation, and salt air exposure.

Heavy-Duty Crate Packing

Assembled frames are wrapped with protective film, foam corner protectors, and sealed into ocean-freight steel or wooden crates.

A folding window stacks multiple sashes neatly to the side to create an expansive clear aperture, ideal for connecting interior spaces to patios or outdoor counters. A lift window uses a counter-balanced or motorized mechanism to raise the sash vertically before opening, providing weather-tight ventilation without intruding on exterior balconies or walkways.

Yes. Our folding window models and select motorised lift systems offer bottomless or recessed floor track configurations. This allows the lower track to be fully embedded into the finished floor build-up for barrier-free transitions.

The flagship 200 Summit Series motorised lift window accommodates total clear opening widths up to 6.0 meters, powered by an internal rack-and-pinion drive gear with multi-point safety sensors.

Motorised lift systems engineered by Meric Window Systems Co., Ltd. feature a dual-channel frame design where the high-visibility stainless steel mesh insect screen is built directly into the primary aluminium profile, operating seamlessly on the same track mechanism.
