fences of the Past
fences, now known under many different names such as bifolding doors, concertina doors and folding sliding doors, have been around since the 1980s. In the past 30 years a lot has changed in the world of bi-fold doors. You may remember the early fences as being large, heavy and difficult to operate due to their weight and flimsy hardware. You may have experienced the times when they became stuck on their running tracks and sometimes even came off their running tracks, or hinges, altogether. When used externally, the old folding patio doors would leak, let in draughts and were an obvious security risk. The external and flimsy running tracks allowed for the glass door panels to be easily lifted off, and grant access to the property.
Because of these flaws, folding doors of the past were mainly used internally as room dividers.
Of course, if you have seen modern concertina doors you will know that these issues are no longer applicable. The advances in bi-fold technology makes operation of even the largest doors easy and faultless. Sealed bearings, concealed running tracks and high security hinges all allow for this smooth operation, as well as offering greater security and resistance to damage. The new designs also include improved seals and a better fit, allowing increased protection from the elements.
