Aluminium Folding Doors & Bifold Door Systems
Engineering Excellence
High-Performance Thermal Break Bifold Doors for Global Architecture
Engineered by Meric Window Systems Co., Ltd., our heavy-duty aluminium folding door systems open entire wall sections seamlessly. Designed with precision thermal breaks, multi-panel stacking configurations, and continuous weather sealing, these bifold doors connect luxury indoor living spaces directly to outdoor terraces, pools, and garden courtyards.
Whether specified for high-end residential villas, oceanfront resorts, or vibrant commercial dining spaces, every folding door unit is manufactured to exact structural and aesthetic standards. By extruding high-tensile 6063-T5 aluminium profiles with reinforced PA66 polyamide insulating strips, Meric Window Systems delivers optimal thermal insulation, structural rigidity, and long-term operating stability under harsh weather conditions.

Key System Advantages
Designed for Structural Integrity and Daily Operating Ease
Built to accommodate expansive structural openings while maintaining slim sightlines and weather-tight protection.
Uninterrupted View & Full Width Access
Panels stack tightly to either side, opening up to 95% of the total wall expanse. Optional flush threshold tracks ensure seamless transition across indoor and outdoor flooring.
Multi-Layer Weather Defense
Integrated EPDM gaskets and overlapping profile joints block heavy rain, wind infiltration, and acoustic noise, maintaining high indoor comfort across all climate zones.
Flexible Access Pass Door
Configurations with odd panel numbers allow a single main sash to function as a daily hinged access door without unlocking the complete folding system.
Enhanced Security Systems
Multi-point locking gear, shoot-bolt locking rods, and anti-lift top guides provide robust structural resistance against forced entry and high wind pressure.
Custom Architectural Powder Coating
Available in a vast array of RAL custom shades, textured metallic coatings, and weather-resistant PVDF finishes tailored for coastal or high-UV environments.
