Names overlap
Bifold, bi-fold, bifolding, folding and accordion are often used for related panel systems. Product names alone do not define performance.
Inspect the actual path
Compare hinges, carriers, panel groups, top or bottom support, stack size, traffic panels and locking sequence.
Check exterior suitability
Interior accordion partitions and exterior weather-rated glass doors solve different problems. Frame, sill, glass, seals and testing must match the application.
Quote the exact system
Use a drawing, opening record and specification instead of relying on a generic category label.
Turn the guide into a real opening schedule.
Keep every dimension, option, pressure, document, and delivery note connected to the same opening ID.
