FAQs About Bi-Fold Windows

What is a bifold window?

A bifold window consists of multiple panels connected by hinges that fold and slide to one or both sides. It creates a wide, open space—perfect for connecting indoor areas with patios, kitchens, or bars.

Yes. APRO bifold windows use insulated aluminum frames and energy-efficient glazing options like double or Low-E glass to reduce heat loss and maintain indoor comfort.

They are ideal for kitchen pass-throughs, entertaining areas, patios, and commercial bars—anywhere you want airflow, visibility, and ease of access between spaces.

 

Our bifold windows come with multi-point locking systems, reinforced frames, and strong hinges for superior security when closed and locked.

 

Absolutely. You can choose the panel configuration, frame color, glass type, hardware finish, and even add built-in screens or blinds to match your project’s needs.

 

Yes. With aluminum frames and quality track systems, they’re rust-resistant, easy to clean, and designed for long-term, low-maintenance use.
