Bi-Fold Door System

Product Description

Bi-Fold Systems™ have simplified interior Bi Fold doors, so they perform and are installed just like a standard interior door. Bi Fold doors are a great space saving design solution, but are frustratingly slow to install, fail over a period of time and require periodic fixing by builders. We've removed all the weak components of existing Bi Folds and replaced them with 5 key essential parts. The result is simplicity, robust and reliability for customer satisfaction.

After 3 years of research and development, BFS is proud to launch its Patented Bi-Fold Door System to New Zealand's architects, designers, builders, developers and homeowners. In testing we activated our system to over 105,000 opening and closing movements without any sign of wear and tear. We would like you to be as confident in our product as we are, so we offer a standard 30 year warranty.

The unique BFS hinge bears the weight of the doors, sliding the guide wheel along a custom made, pre glued rebated channel, allowing magnets to align and snap shut against the door stops. With the guiding channel rebated into the head it is visually hidden with no tracking visible and no bottom tracking required. All door architraves can now be at a consistent height throughout the build. The perfect match.

Consistent door gaps of 3mm at the top and sides with a 5mm gap between doors leaves an end result which is both architecturally and aesthetically pleasing and Bi Fold doors that actually function correctly.
