uPVC Bi-Fold Doors Sydney
Panels fold back on themselves and stack clear of the opening, so the wall between inside and outside effectively disappears.
Where a slider always leaves at least one panel covering the opening, a bi-fold folds its panels concertina-style and stacks them to one or both sides, clearing very nearly the whole aperture. That is the appeal, and for a living area that opens onto a deck or courtyard it changes how the room is used. It is also the most mechanically demanding door in the range, which is reflected in the price - from $3,200 for a 2400 x 2100mm double glazed opening.
Every window and door is made to measure, so the figure above is a starting point rather than a quote. Size, glazing specification, colour and access all move it - the pricing guide explains each factor, and a free on-site measure produces an itemised price.
Getting the panel count right
Panel width is the decision that matters. Narrow panels stack into a smaller bundle but add more hinges and more joints; wide panels look cleaner but are heavier to fold and stack deeper. For most Sydney openings between 2.4m and 4.8m we are choosing between three and five panels, and the right answer depends on where the stack can sit without fouling a wall return or a balustrade.
Traffic doors
One panel can be hung as a conventional hinged traffic door, so day-to-day use does not mean folding the whole set back. If the door is your main route to the clothesline or the barbecue, specify it - it is the difference between a door you use and a door you open twice a year.
Weather and hardware
Every fold is a joint, so gasket detailing and hardware quality carry more weight here than on any other product. Ours run European gear with multi-point locking on the lead panel and full-perimeter seals, and the tracks are drained rather than sealed - a bi-fold that cannot shed water at the sill will find its way into your floor.

Sliding Doors
The practical opening for balconies and courtyards - nothing swings, so the space either side of the door stays usable.
From $1,850
French Doors
A pair of hinged glazed leaves meeting in the centre - the classic European opening, and the one that suits a period Sydney home best.
From $2,600
Lift and Slide Doors
Turning the handle lifts the entire sash off its seals onto the rollers - so a panel weighing hundreds of kilos moves with one hand.
Tilt and Slide Doors
A sliding door that also tilts - secure background ventilation without leaving a full-height opening standing open.
Stacking Doors
Multiple sliding panels that gather behind one another at one end of the opening, clearing most of the aperture without folding.
Entrance Doors
The front door is usually the weakest thermal element left in a house after the windows are done - and the easiest one to forget.
