The Back Wall Sail
Fully opened, stacked bifold door leaves act like a massive sail on the back of a property.
Sudden coastal wind gusts catch these loose metal panels, hurling them violently backward against exterior masonry or structural garden pillars. This unhindered impact causes immediate, expensive structural damage to the entire door set. Leaving panels unlatched during a breeze destroys the frame alignment completely.
Cracking the Finish and Bearings
Metal-on-stone contact cracks the premium powder-coated aluminium finish instantly.
Chips in the paint expose raw aluminium to salty coastal air, triggering rapid oxidisation and corrosion. The violent slamming vibration also fractures the internal roller carriage bearings inside the tracking system. Broken carriage bearings jam the sliding mechanism permanently, turning a smooth patio door into a heavy, dragging hazard.
The Failure of Standard Stops
Basic rubber door stops or cheap plastic clips fail to hold multiple stacked panels against heavy Bournemouth wind pressures.
The combined weight of three or four heavy glass sashes easily overpowers basic hinge resistance. Unsecured door panels swing freely back and forth. This constant movement snaps protruding handles, dents the metal profiles, and risks shattering adjacent glass units during sudden changes in weather.
The Magnetic Lock Solution
Securing the door stack requires a matched set of magnetic bifold door holders.
These heavy-duty metal blocks mount directly onto the top and bottom rails of adjacent door panels. The high-strength internal magnetic cores lock the folded door sashes completely rigid against storm forces. Releasing the doors requires a deliberate physical pull, preventing any accidental panel movement during high winds.
