Our bi-fold door systems provide smooth, reliable operation and superb design.

Our bi-fold doors have a reliable bottom-mounted roller system for smooth, reliable performance. Our heavy duty quad rollers run on a matching double track for optimum performance and support, this ensures heavy panels operate easily. 

Where you have an uneven number of panels, it is a good idea is to include a hinged door in the bi-fold door set, this allows convenient exit or entry without opening up the bi-fold door.

Residential Bottom-rolling Bifold | Series 548

  • Bottom-rolling panels run on rollers at the sill ensuring they don't pull the bi-fold door lintel down and therefore they work smoothly over the long haul. Top clearance allows up to 6mm of lintel movement.
  • Series 548 bi-fold door transoms have a narrow profile. This allows a designer to include 2100mm-high doors plus an overlight in a standard 2400mm-high opening. (Opening sashes as well as fixed overlights are available).
  • Very deep water ‘head’ at the bottom. The bigger this measurement - from drainage hole to the inside leg - the more assured the water drainage in wet or stormy conditions.
  • The Vantage Series 548 High Performance Bi-fold door features an unusual design embellishment - extra wide top and bottom rails that give the door the chunky appearance of traditional timber designs.
  • The centre hinge between bi-fold door panels has a built-in handle to allow the home owner to easily pull the panels back into the closed position.
  • The Series 548 bi-fold door will accept Centor™ S1 screen.
