What is a Bi-Fold Window?

A folding (bi-fold) window is made of multiple glass panels hinged together, which fold concertina-style and stack to one or both sides on a top-hung or bottom-rolling track. This lets a wide opening — sometimes an entire wall — fold open almost completely.

BOYCE’s folding systems use top pivot arms and bottom ball-bearing rollers engineered to keep heavy glass panels moving smoothly for years, with a traffic door option so the space can be used daily without folding back every panel.

Window systems, by project type.

See how we craft your windows in a whole new way across all our projects.

Folding Window | Top Support Arms

Reinforced top pivot arms carry the weight of each panel, keeping the folding action smooth and reducing strain on the track over years of daily use.

Folding Window | Bottom Roller Smoothness

Adjustable ball-bearing rollers at the base of each panel keep the whole run gliding evenly, even after years of exposure to dust and weather.

Folding Window | Traffic Door Convenience

An inline traffic door lets you step in and out without folding back the entire wall — the full opening is there when you want it.

about Aluminum Bi-Fold Windows- FAQ

What are the advantages of aluminum folding windows?
+
A folding window wall can open up to 90% of the total width — no other window system opens a wall this completely. Combined with a traffic door, it works for both everyday use and full indoor-outdoor entertaining.
What are the drawbacks compared to sliding windows?
+
Folded panels need wall space to stack against on one or both sides, and the hinge joints mean slightly more seals to maintain than a sliding track. For narrow openings, a sliding window is often more practical.
How wide can a single folding window run be?
+
Standard runs support up to 7 panels at 600-900mm each — for wider openings, we can split the run into two stacks on either side (bi-parting) or add a support post at the midpoint.
How much do aluminum folding windows cost?
+
Pricing depends on panel count, glass makeup and hardware brand. Send your opening width and we'll return an itemized quote — not a lump-sum estimate — within 24 hours.
Is a folding window weatherproof when fully closed?
+
Yes — brush seals and EPDM gaskets run along every panel joint and the leading panel locks with a multi-point mechanism, giving a consistent seal across the full width when closed.
