Durafold 1000 Bifolding Doors

Trade installers also benefit from the best-selling bifolding doors, designed for reliability, style and an extensive choice of special colours.
The colour codes with Durafold 1000 bifolding doors are familiar to the trade from the KL references used by Smart Systems. Also available are the Sensations range of colours.

Emperor Concealed Bifolding Doors
The Emperor Bifolding doors product by Duration Windows uses the company’s own extrusions and design.
The standout feature of these doors is a hidden hinges between the door leaves. No visible hinges, a cleaner look and contemporary lines make this door suitable for those projects needing a different style and more unique product.

Another great feature around these flushline handles is even better stacking of the folded panels. And just like the hidden hinges, they keep the inside of the doors clean as they also don’t need an additional D-Handle for pulling on the door sashes.
Finally, the mullions sightlines of these doors come at just 135mm making them slimmer than Origin, Visofold, Senior Systems and many other well-known brands. As a trade supply bifold, Emperor provides installers with something altogether different from a reliable and expert trade supplier.

Heritage Bifolding Doors
For steel-look products, Duration windows use the Durafold Slimline model, expertly modified and customised creating an authentic steel-look and heritage version.
