The most common upgrade we do in the newer estates of Glenmore Park, Jordan Springs, Caddens and Claremont Meadows is replacing the builder grade two panel sliding door onto the alfresco. The choice is almost always between a stacking door and a bifold. Here is how we talk it through.
How much of the opening do you get?
A two panel slider opens half the width. A three panel stacking door opens two thirds, and a four or six panel layout stacking both ways opens more. A bifold opens the whole width, with the folded panels sitting at one or both ends.
Flyscreens and security
This is where most families decide. A stacking door has a flyscreen track built into the frame and takes a sliding security screen, so the door can be open and screened on a summer night. A bifold has no standard flyscreen; retractable pleated screens exist but cost extra and are more delicate. In Penrith summers the screen matters.
Cost
A KlassicView stacking door is noticeably cheaper than a HarbourView bifold for the same opening because the panels are simpler and there is less hardware. If the budget is fixed, the stacker usually wins.
Sill height and access
A top rolling bifold allows a low sill for level access from the living room to the alfresco, which stackers cannot match. If someone in the house uses a wheelchair or walker, that can decide it.
Our usual advice
Most alfresco openings in project homes are 2.4 to 3.6 metres and get a three or four panel stacking door with a sliding ScreenGuard or PerfGuard security panel. Openings over 4 metres, or homes where the whole wall should disappear for entertaining, get a bifold. We quote both so you can compare. Book a free measure and we will bring the samples.
