Common Issues with Smart Systems (Visofold) Bifold Doors

 

Even premium aluminium bifolds like Smart Systems can develop issues. Problems may arise from normal use or poor installation, which can lead to long-term operational challenges.

​

Common issues include:

​

• Dropped or Sagging Panels – Worn rollers or misaligned tracks can cause panels to sag. Incorrect installation can leave panels off-level, stressing hinges and locks.

• Stiff or Sticky Operation – Debris, roller wear, or temperature changes can make operation difficult. Installation misalignment can worsen this.

• Worn Rollers or Wheels – Uneven folding or dragging panels, especially when weight distribution is uneven.

• Hinge & Pivot Problems – Misalignment from installation or building settling causes jerky movement and extra stress.

• Track Misalignment – Tracks not level or square cause rubbing and dragging.

• Locking Mechanism Issues – Misaligned multi-point locks may fail to engage properly.

​

Toe and Heel Misalignment

 

A long-term issue caused by installation is toe and heel misalignment, where the top (toe) and bottom (heel) of a panel are not perfectly aligned within the frame.

​

Signs:

​

• Panels appear tilted when folded or closed

• One side drags while operating

• Increased stress on rollers, hinges, and locks

​

Causes:

​

• Panels not leveled at installation

• Frames not squared correctly

• Building settling over time

​

How Pro-Lock Corrects Toe and Heel Misalignment:

​

• Realigning panels at the toe and heel for smooth, even operation

• Adjusting hinges, pivots, and rollers to distribute weight correctly

• Correcting track alignment where necessary

• Providing advice on ongoing maintenance

​

By addressing both normal wear and installation-related issues, Pro-Lock restores Visofold doors to smooth, secure, and reliable operation.
