Fitting new thermally efficient double glazed bi-folding and sliding doors in the UK is certainly a gamble when it comes to the weather, but there are some configurations that are operationally better than others. The clue is in the name “bi-fold”. The key thing with bi-folding doors is to remember that each “pair” of bi-folds, opens and closes in tandem, so each section cannot operate individually, as each bi-fold section (2 panes) are in-effect one. As these two folding door sections are permanently linked together (folding up flat against one another) they cannot accommodate a normal door handle, nor can one of these two pane sections operate as a travel door without the other section opening or closing at the same time.
As a result,…
Whether a property owner has decided on a replacement aluminium, composite, steel, timber or UPVC door(s), each type of material, as well as each “door system” has its limits. The minimum and maximum opening widths and heights that can be achieved vary considerably from one product to another, and also from one type of door to another.
Regardless of whether one is replacing a front, back, garage, French, sliding, folding or stable door, not every size of opening or configuration can be achieved. For example, when it comes to bi-folding doors, there are practical limits set by the systems manufacturers for their products, outside of which not only will the doors be likely to fail operationally, but they will not be covered by the manufacturers…
