Engineered Aluminum Folding Window Systems
At Vexis Windows & Doors Co., Ltd., our aluminum folding windows (also known as bifold windows) are engineered with high-precision 6063-T5 aluminum profiles and PA66 nylon thermal break strips. Designed to stack neatly to one or both sides, they achieve up to a 95%-100% frame-free clear opening rate.
Ideal for luxury residential villas, resort patios, commercial bar counters, and outdoor kitchens, our folding window systems integrate multi-point locking hardware, continuous EPDM weather sealing gaskets, and stainless-steel heavy-duty bottom rollers for effortless daily operation.

Key Advantages of Vexis Folding Windows
1. Maximum Ventilation
Unlike standard sliding or casement units, folding sashes stack completely out of the sightline to create an uninterrupted indoor-outdoor flow.
2. Space-Saving Operation
Compact sash geometry ensures folded panels rest tightly against side walls, preventing space intrusion on balconies and kitchen pass-through counters.
3. All-Weather Sealing
Dual EPDM sealing strips paired with high-performance drain tracks ensure wind pressure resistance up to Class 8 and superior water tightness.
